Based on this, it is clear that images with an average pixel value below 10 would provide little utility in inferential tasks and can safely be ignored. Fundamental to the project was the capture of (1) audio signals with the capacity to recognize human speech (ranging from 100Hz to 4kHz) and (2) monochromatic images of at least 10,000 pixels. Images were captured at a rate of 1 frame per second, while all environmental readings were captured every ten seconds. This process is irreversible, and so the original details on the images are unrecoverable. The median cut-off value was 0.3, though the values ranged from 0.2 to 0.6. The TVOC and CO2 sensor utilizes a metal oxide gas sensor, and has on-board calibration, which it performs on start-up and at regular intervals, reporting eCO2 and TVOC against the known baselines (which are also recorded by the system). (c) and (d) H3: Main and top level (respectively) of three-level home. See Table1 for a summary of modalities captured and available. To show the results of resolution on accuracy, we ran the YOLOv5 algorithm on balanced, labeled datasets at a variety of sizes (3232 pixels up-to 128128 pixels), and compared accuracy (defined as the total that were correctly identified divided by the total classified) across homes. In each 10-second audio file, the signal was first mean shifted and then full-wave rectified. Home layouts and sensor placements. The optimal cut-off threshold that was used to classify an image as occupied or vacant was found through cross-validation and was unique for each hub. It mainly includes radar-related multi-mode detection, segmentation, tracking, freespace space detection papers, datasets, projects, related docs Radar Occupancy Prediction With Lidar Supervision While Preserving Long-Range Sensing and Penetrating Capabilities: freespace generation: lidar & radar: Values given are the number of files collected for that modality in that location, relative to the total number that could be collected in a day, averaged over all the days that are presented in the final dataset. While all of these datasets are useful to the community, none of them include ground truth occupancy information, which is essential for developing accurate occupancy detection algorithms. It includes a clear description of the data files. GitHub is where people build software. Additional key requirements of the system were that it (3) have the ability to collect data concurrently from multiple locations inside a house, (4) be inexpensive, and (5) operate independently from residential WiFi networks. The final distribution of noisy versus quiet files were roughly equal in each set, and a testing set was chosen randomly from shuffled data using a 70/30 train/test split. (a) and (b) are examples of false negatives, where the images were labeled as vacant at the thresholds used (0.3 and 0.4, respectively). In this study, a neural network model was trained on data from room temperature, light, humidity, and carbon dioxide measurements. Classification was done using a k-nearest neighbors (k-NN) algorithm. Please For example, images and audio can both provide strong indications of human presence. Next, processing to validate the data and check for completeness was performed. The limited availability of data makes it difficult to compare the classification accuracy of residential occupancy detection algorithms. Due to the increased data available from detection sensors, machine learning models can be created and used to detect room occupancy. Each hub file or directory contains sub-directories or sub-files for each day. You signed in with another tab or window. Change Loy, C., Gong, S. & Xiang, T. From semi-supervised to transfer counting of crowds. See Technical Validation for results of experiments comparing the inferential value of raw and processed audio and images. However, we believe that there is still significant value in the downsized images. See Table4 for classification performance on the two file types. See Fig. This repository hosts the experimental measurements for the occupancy detection tasks. The publicly available dataset includes: grayscale images at 32-by-32 pixels, captured every second; audio files, which have undergone processing to remove personally Additionally, other indoor sensing modalities, which these datasets do not capture, are also desirable. 2021. Three data sets are submitted, for training and testing. Zone-labels for the images are provided as CSV files, with one file for each hub and each day. Section 5 discusses the efficiency of detectors, the pros and cons of using a thermal camera for parking occupancy detection. Data Set License: CC BY 4.0. Review of occupancy sensing systems and occupancy modeling methodologies for the application in institutional buildings. The data includes multiple age groups, multiple time periods and multiple races (Caucasian, Black, Indian). Soltanaghaei, E. & Whitehouse, K. Walksense: Classifying home occupancy states using walkway sensing. The data described in this paper was collected for use in a research project funded by the Advanced Research Projects Agency - Energy (ARPA-E).

If nothing happens, download Xcode and try again. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Through sampling and manual verification, some patterns in misclassification were observed. The results show that while the predictive capabilities of the processed data are slightly lower than the raw counterpart, a simple model is still able to detect human presence most of the time. Gao, G. & Whitehouse, K. The self-programming thermostat: Optimizing setback schedules based on home occupancy patterns. Dodier RH, Henze GP, Tiller DK, Guo X. The highest likelihood region for a person to be (as predicted by the algorithm) is shown in red for each image, with the probability of that region containing a person given below each image, along with the home and sensor hub. The images shown are 112112 pixels. Points show the mean prediction accuracy of the algorithm on a roughly balanced set of labeled images from each home, while the error bars give the standard deviations of all observations for the home. This outperforms most of the traditional machine learning models. If the time-point truly was mislabeled, the researchers attempted to figure out why (usually the recording of entrance or exit was off by a few minutes), and the ground truth was modified. Figueira, D., Taiana, M., Nambiar, A., Nascimento, J. Example of the data records available for one home. A tag already exists with the provided branch name. The methods to generate and check these labels are described under Technical Validation. Ground-truth occupancy was obtained from time stamped pictures that were taken every minute. The data we have collected builds on the UCI dataset by capturing the same environmental modalities, while also capturing privacy preserved images and audio. Thus, a dataset containing privacy preserved audio and images from homes is a novel contribution, and provides the building research community with additional datasets to train, test, and compare occupancy detection algorithms. WebOccupancy Detection Data Set Download: Data Folder, Data Set Description. False negatives were not verified in similar fashion, as false negatives from the images (i.e., someone is home but the camera does not see them) were very common, since the systems ran 24-hours a day and people were not always in rooms that had cameras installed. The results show that feature selection can have a significant impact on prediction accuracy and other metrics when combined with a suitable classification model architecture. For the duration of the testing period in their home, every occupant was required to carry a cell phone with GPS location on them whenever they left the house. like this: from detection import utils Then you can call collate_fn Wang F, et al. Occupancy detection of an office room from light, temperature, humidity and CO2 measurements. To aid in retrieval of images from the on-site servers and later storage, the images were reduced to 112112 pixels and the brightness of each image was calculated, as defined by the average pixel value. Additionally, radar imaging can assess body size to optimize airbag deployment depending on whether an adult or a child is in the seat, which would be more effective than existing weight-based seat sensor systems. It is now read-only. Blue outlined hubs with blue arrows indicate that the hub was located above a doorway, and angled somewhat down. and S.S. conceived and oversaw the experiment. sharing sensitive information, make sure youre on a federal We also cannot discount the fact that occupants behavior might have been altered somewhat by the knowledge of monitoring, however, it seems unlikely that this knowledge would have led to increased occupancy rates. WebOccupancy-detection-data. The final data that has been made public was chosen so as to maximize the amount of available data in continuous time-periods. National Library of Medicine Because of IRB restrictions, no homes with children under the age of 18 were included. 7d,e), however, for the most part, the algorithm was good at distinguishing people from pets. Turley C, Jacoby M, Pavlak G, Henze G. Development and evaluation of occupancy-aware HVAC control for residential building energy efficiency and occupant comfort. M.J. created the data acquisition system, performed all data collection tasks, processed and validated the collected data, and wrote the manuscript. Newer methods include camera technologies with computer vision10, sensor fusion techniques11, occupant tracking methods12, and occupancy models13,14. Figure4 shows examples of four raw images (in the original 336336 pixel size) and the resulting downsized images (in the 3232 pixel size). (c) Waveform after full wave rectification. The data from homes H1, H2, and H5 are all in one continuous piece per home, while data from H3, H4, and H6 are comprised of two continuous time-periods each. Due to the increased data available from detection sensors, machine learning models can be created and used OMS generally uses camera equipment to realize the perception of passengers through AI algorithms. As might be expected, image resolution had a significant impact on algorithm detection accuracy, with higher resolution resulting in higher accuracy. These include the seat belt warning function, judging whether the passengers in the car are seated safely, whether there are children or pets left alone, whether the passengers are wearing seat belts, etc. Five (5) sensor hubs, each containing environmental sensors, a microphone, and a camera, An industrial computer, to act as an on-site server, A wireless router, to connect the components on-site. HHS Vulnerability Disclosure, Help This is likely because the version of the algorithm used was pre-trained on the Common Objects in Context (or COCO) dataset24, which includes over 10,000 instances each of dogs and cats. Webusetemperature,motionandsounddata(datasets are not public). Because data could have been taken with one of two different systems (HPDred or HPDblack), the sensor hubs are referred to by the color of the on-site server (red or black). Currently, rice panicle information is acquired with manual observation, which is inefficient and subjective.

For instance, false positives (the algorithm predicting a person was in the frame when there was no one) seemed to occur more often on cameras that had views of big windows, where the lighting conditions changed dramatically. Accurate occupancy detection of an office room from light, temperature, humidity and CO2 measurements using statistical learning models. & Hirtz, G. Improved person detection on omnidirectional images with non-maxima suppression. WebOccupancy Experimental data used for binary classification (room occupancy) from Temperature, Humidity, Light and CO2. These labels were automatically generated using pre-trained detection models, and due to the enormous amount of data, the images have not been completely validated. The climate in Boulder is temperate, with an average of 54cm of annual precipitation, in the form of rain in the summer and snow in the winter. Volume 112, 15 January 2016, Pages 28-39. Caleb Sangogboye, F., Jia, R., Hong, T., Spanos, C. & Baun Kjrgaard, M. A framework for privacy-preserving data publishing with enhanced utility for cyber-physical systems. Surprisingly, the model with temperature and light outperformed all the others, with an accuracy of 98%. Are you sure you want to create this branch? Due to the slow rate-of-change of temperature and humidity as a result of human presence, dropped data points can be accurately interpolated by researchers, if desired. The collecting scenes of this dataset include indoor scenes and outdoor scenes (natural scenery, street view, square, etc.). Please (d) and (e) both highlight cats as the most probable person location, which occurred infrequently. See Table2 for a summary of homes selected. In some cases this led to higher thresholds for occupancy being chosen in the cross-validation process, which led to lower specificity, along with lower PPV. The model integrates traffic density, traffic velocity and duration of instantaneous congestion. There may be small variations in the reported accuracy. In The 2nd Workshop on occupancy was obtained from time stamped pictures that were taken every minute. Individual sensor errors, and complications in the data-collection process led to some missing data chunks. The results are given in Fig. (g) H6: Main level of studio apartment with lofted bedroom. Because the environmental readings are not considered privacy invading, processing them to remove PII was not necessary. Also reported are the point estimates for: True positive rate (TPR); True negative rate (TNR); Positive predictive value (PPV); and Negative predictive value (NPV). Currently, the authors are aware of only three publicly available datasets which the research community can use to develop and test the effectiveness of residential occupancy detection algorithms: the UCI16, ECO17, and ecobee Donate Your Data (DYD) datasets18. Other studies show that by including occupancy information in model predictive control strategies, residential energy use could be reduced by 1339%6,7. The occupants cover a range of ages and relationships and consisted of couples, roommate households, and one family with adult children who were home during part of the testing duration. The data includes multiple ages and multiple time periods. Created by university of Nottingham WebData Descriptor occupancy detection dataset Margarite Jacoby 1 , Sin Yong Tan 2, Gregor Henze1,3,4 & Soumik Sarkar 2. Install all the packages dependencies before trying to train and test the models. Ground-truth occupancy was obtained from time stamped pictures that were taken every minute. It mainly includes radar-related multi-mode detection, segmentation, tracking, freespace space detection papers, datasets, projects, related docs Radar Occupancy Prediction With Lidar Supervision While Preserving Long-Range Sensing and Penetrating Capabilities: freespace generation: lidar & radar: The research presented in this work was funded by the Advanced Research Project Agency - Energy (ARPA-E) under award number DE-AR0000938. A tag already exists with the provided branch name. Since higher resolution did have significantly better performance, the ground truth labeling was performed on the larger sizes (112112), instead of the 3232 sizes that are released in the database. Description Three data sets are submitted, for training and testing. The YOLOv5 labeling algorithm proved to be very robust towards the rejection of pets. These predictions were compared to the collected ground truth data, and all false positive cases were identified. Overall the labeling algorithm had good performance when it came to distinguishing people from pets. Abstract: Experimental data used for binary classification (room occupancy) from Jocher G, 2021. ultralytics/yolov5: v4.0 - nn.SiLU() activations, weights & biases logging, PyTorch hub integration. The data acquisition system, coined the mobile human presence detection (HPDmobile) system, was deployed in six homes for a minimum duration of one month each, and captured all modalities from at least four different locations concurrently inside each home. Please do not forget to cite the publication! Accuracy, precision, and range are as specified by the sensor product sheets. Images include the counts for dark images, while % Dark gives the percentage of collected images that were counted as dark with respect to the total possible per day. Summaries of these can be found in Table3. To increase the utility of the images, zone-based labels are provided for the images. Training and testing sets were created by aggregating data from all hubs in a home to create larger, more diverse sets. The authors wish the thank the following people: Cory Mosiman, for his instrumental role in getting the data acquisition system set up; Hannah Blake and Christina Turley, for their help with the data collection procedures; Jasmine Garland, for helping to develop the labeled datasets used in technical validation; the occupants of the six monitored homes, for letting us invade their lives. binary classification (room occupancy) from Temperature,Humidity,Light and CO2. occupancy was obtained from time stamped pictures that were taken every minute. Accurate occupancy detection of an office room from light, temperature, humidity and CO2 measurements using statistical learning models. Luis M. Candanedo, Vronique Feldheim. Monthly energy review. The homes included a single occupancy studio apartment, individuals and couples in one and two bedroom apartments, and families and roommates in three bedroom apartments and single-family houses. The SBCs are attached to a battery, which is plugged into the wall, and serves as an uninterruptible power supply to provide temporary power in the case of a brief power outage (they have a seven hour capacity). TensorFlow, Keras, and Python were used to construct an ANN. 1a for a diagram of the hardware and network connections. Studies using PIR sensors and smart thermostats show that by accounting for occupancy use in HVAC operations, residential energy use can be reduced by 1547%35. 5 for a visual of the audio processing steps performed. Download: Data Folder, Data Set Description. The illuminance sensor uses a broadband photodiode and infrared photodiode, and performs on-board conversion of the analog signal to a digital signal, meant to approximate the human eye response to the light level. Audio files were processed in a multi-step fashion to remove intelligible speech. Implicit sensing of building occupancy count with information and communication technology data sets. The age distribution ranges from teenager to senior. The two homes with just one occupant had the lowest occupancy rates, since there were no overlapping schedules in these cases. WebThe publicly available dataset includes: grayscale images at 32-by-32 pixels, captured every second; audio files, which have undergone processing to remove personally identifiable Ideal hub locations were identified through conversations with the occupants about typical use patterns of the home. Contact us if you have any Legal statement and Web[4], a dataset for parking lot occupancy detection. indicates that the true value is within the specified percentage of the measured value, as outlined in the product sheets. If nothing happens, download Xcode and try again. The pandas development team. Finally, audio was anonymized and images downsized in order to protect the privacy of the study participants.

Several of the larger homes had multiple common areas, in which case the sensors were more spread out, and there was little overlap between the areas that were observed. sign in to use Codespaces. The on-site server was needed because of the limited storage capacity of the SBCs. Hardware used in the data acquisition system. Luis M. Candanedo, Vronique Feldheim. Thus new pixel values are generated from linear combinations of the original values. VL53L1X: Time-of-Flight ranging sensor based on STs FlightSense technology. Huchuk B, Sanner S, OBrien W. Comparison of machine learning models for occupancy prediction in residential buildings using connected thermostat data. Many of these strategies are based on machine learning techniques15 which generally require large quantities of labeled training data. Multi-race Driver Behavior Collection Data, 50 Types of Dynamic Gesture Recognition Data, If you need data services, please feel free to contact us at. See Table3 for the average number of files captured by each hub. Variable combinations have been tried as input features to the model in many different ways. Commercial data acquisition systems, such as the National Instruments CompactRio (CRIO), were initially considered, but the cost of these was prohibitive, especially when considering the addition of the modules necessary for wireless communication, thus we opted to design our own system. The method that prevailed is a hierarchical approach, in which instantaneous occupancy inferences underlie the higher-level inference, according to an auto-regressive logistic regression process. E.g., the first hub in the red system is called RS1 while the fifth hub in the black system is called BS5. (c) Custom designed printed circuit board with sensors attached. The paper proposes a decentralized and efficient solution for visual parking lot occupancy detection based on a deep Convolutional Neural Network (CNN) specifically designed for smart cameras. This solution is compared with state-of-the-art approaches using two visual datasets: PKLot, already existing in literature, and CNRPark+EXT. Due to misclassifications by the algorithm, the actual number of occupied and vacant images varied for each hub. In 2020, residential energy consumption accounted for 22% of the 98 PJ consumed through end-use sectors (primary energy use plus electricity purchased from the electric power sector) in the United States1, about 50% of which can be attributed to heating, ventilation, and air conditioning (HVAC) use2. This process works by fixing the pixel values at the edges of the image, then taking weighted averages of the inner pixels, in order to transform from the original size to the target size. R, Rstudio, Caret, ggplot2. sign in To achieve the desired higher accuracy, proposed OccupancySense model detects human presence and predicts indoor occupancy count by the fusion of Internet of Things (IoT) based indoor air quality (IAQ) data along with static and dynamic context data which is a unique approach in this domain. The binary status reported has been verified, while the total number has not, and should be used as an estimate only. (d) Average pixel brightness: 10. Some homes had higher instances of false positives involving pets (see Fig. This series of processing allows us to capture the features from the raw audio signals, while concealing the identity of speakers and ensuring any words spoken will be undecipherable. to use Codespaces. This data diversity includes multiple scenes, 18 gestures, 5 shooting angels, multiple ages and multiple light conditions. When transforming to dimensions smaller than the original, the result is an effectively blurred image. All data was captured in 2019, and so do not reflect changes seen in occupancy patterns due to the COVID-19 global pandemic. The data diversity includes multiple scenes, 50 types of dynamic gestures, 5 photographic angles, multiple light conditions, different photographic distances. Ground-truth occupancy was obtained from time stamped pictures that were taken every minute. All collection code on both the client- and server-side were written in Python to run on Linux systems. In light of recently introduced systems, such as Delta Controls O3 sensor hub24, a custom designed data acquisition system may not be necessary today. WebModern methods for vision-centric autonomous driving perception widely adopt the birds-eye-view (BEV) representation to describe a 3D scene. Spatial overlap in coverage (i.e., rooms that had multiple sensor hubs installed), can serve as validation for temperature, humidity, CO2, and TVOC readings. In most cases, sensor accuracy was traded in favor of system cost and ease of deployment, which led to less reliable environmental measurements. For the sake of transparency and reproduciblity, we are making a small subset (3 days from one home) of the raw audio and image data available by request. The sensors used were chosen because of their ease of integration with the Raspberry Pi sensor hub. 7c,where a vacant image was labeled by the algorithm as occupied at the cut-off threshold specified in Table5. See Fig. (b) Final sensor hub (attached to an external battery), as installed in the homes. The Pext: Build a Smart Home AI, What kind of Datasets We Need. Finally, the signal was downsampled by a factor of 100 and the resulting audio signal was stored as a CSV file. Contact us if you In noise there is recognizable movement of a person in the space, while in quiet there are no audible sounds. The publicly available dataset includes: grayscale images at 32-by-32 pixels, captured every second; audio files, which have undergone processing to remove personally identifiable information; indoor environmental readings, captured every ten seconds; and ground truth binary occupancy status. Summary of the completeness of data collected in each home. An example of this is shown in Fig. Figure3 compares four images from one hub, giving the average pixel value for each.
