The homes and apartments tested were all of standard construction, representative of the areas building stock, and were constructed between the 1960s and early 2000s. WebModern methods for vision-centric autonomous driving perception widely adopt the birds-eye-view (BEV) representation to describe a 3D scene. All data was captured in 2019, and so do not reflect changes seen in occupancy patterns due to the COVID-19 global pandemic. Occupancy detection, tracking, and estimation has a wide range of applications including improving building energy efficiency, safety, and security of the Rice yield is closely related to the number and proportional area of rice panicles. The homes with pets had high occupancy rates, which could be due to pet owners needing to be home more often, but is likely just a coincidence. In terms of device, binocular cameras of RGB and infrared channels were applied. Luis M. Candanedo, Vronique Feldheim. Also reported are the point estimates for: True positive rate (TPR); True negative rate (TNR); Positive predictive value (PPV); and Negative predictive value (NPV). Ground-truth occupancy was obtained from time stamped pictures that were taken every minute. (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). Since the subsets of labeled images were randomly sampled, a variety of lighting scenarios were present. 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).

Some homes had higher instances of false positives involving pets (see Fig. About Trends Portals Libraries . Ground-truth occupancy was obtained from time stamped pictures that were taken every minute. Ground-truth occupancy was obtained from time stamped pictures that were taken every minute. Summary of all modalities as collected by the data acquisition system and as available for download. Hubs were placed only in the common areas, such as the living room and kitchen. Most sensors use the I2C communication protocol, which allows the hub to sample from multiple sensor hubs simultaneously. Hubs were placed either next to or facing front doors and in living rooms, dining rooms, family rooms, and kitchens. There was a problem preparing your codespace, please try again. Data that are captured on the sensor hub are periodically transmitted wirelessly to the accompanying VM, where they are stored for the duration of the testing period in that home. After training highly accurate image classifiers for use in the ARPA-E SENSOR project, these algorithms were applied to the full collected image sets to generate binary decisions on each image, declaring if the frame was occupied or vacant. WebThe field of machine learning is changing rapidly. This dataset can be used to train and compare different machine learning, deep learning, and physical models for estimating occupancy at enclosed spaces. The DYD data is collected from ecobee thermostats, and includes environmental and system measurements such as: runtime of heating and cooling sources, indoor and outdoor relative humidity and temperature readings, detected motion, and thermostat schedules and setpoints. Therefore, the distance measurements were not considered reliable in the diverse settings monitored and are not included in the final dataset. Candanedo LM, Feldheim V. Accurate occupancy detection of an office room from light, temperature, humidity and CO2 measurements using statistical learning models. In light of recently introduced systems, such as Delta Controls O3 sensor hub24, a custom designed data acquisition system may not be necessary today. You signed in with another tab or window. Since the hubs were collecting images 24-hours a day, dark images accounted for a significant portion of the total collected, and omitting these significantly reduces the size of the dataset. To ensure accuracy, ground truth occupancy was collected in two manners. Ground-truth occupancy was In addition to the environmental readings shown in Table1, baseline measurements of TVOC and eCO2, as collected by the sensors, are also included in the files. 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 data described in this paper was collected for use in a research project funded by the Advanced Research Projects Agency - Energy (ARPA-E). & Bernardino, A. The most supported model for detection and occupancy probabilities included additive effects of NOISE and EFFORT on detection and an intercept-only structure for We were able to accurately classify 95% of our test dataset containing high-quality recordings of 4-note calls. Timestamp format is consistent across all data-types and is given in YY-MM-DD HH:MM:SS format with 24-hour time. See Fig. Summary of the completeness of data collected in each home. "-//W3C//DTD HTML 4.01 Transitional//EN\">, Occupancy Detection Data Set We have also produced and made publicly available an additional dataset that contains images of the parking lot taken from different viewpoints and in different days with different light conditions.

CNR-EXT captures different situations of light conditions, and it includes partial occlusion patterns due to obstacles (trees, lampposts, other cars) and partial or global shadowed cars. The video shows the visual occupancy detection system based deployed at the CNR Research Area in Pisa, Italy. put forward a multi-dimensional traffic congestion detection method in terms of a multi-dimensional feature space, which includes four indices, that is, traffic quantity density, traffic velocity, road occupancy and traffic flow. 2 for home layouts with sensor hub locations marked. The results are given in Fig. A tag already exists with the provided branch name. See Fig. Yang J, Santamouris M, Lee SE. This is most likely due to the relative homogeneity of the test subjects, and the fact that many were graduate students with atypical schedules, at least one of whom worked from home exclusively. Leave your e-mail, we will get in touch with you soon. (eh) Same images, downsized to 3232 pixels. (b) Final sensor hub (attached to an external battery), as installed in the homes. In addition, zone-labels are provided for images, which indicate with a binary flag whether each image shows a person or not. Accuracy, precision, and range are as specified by the sensor product sheets. However, simple cameras are easily deceived by photos. From these verified samples, we generated point estimates for: the probability of a truly occupied image being correctly identified (the sensitivity or true positive rate); the probability of a truly vacant image being correctly identified (the specificity or true negative rate); the probability of an image labeled as occupied being actually occupied (the positive predictive value or PPV); and the probability of an image labeled as vacant being actually vacant (the negative predictive value or NPV). As necessary to preserve the privacy of the residents and remove personally identifiable information (PII), the images were further downsized, from 112112 pixels to 3232 pixels, using a bilinear interpolation process. sign in Microsoft Corporation, Delta Controls, and ICONICS. Because of IRB restrictions, no homes with children under the age of 18 were included. Days refers to the number of days of data that were released from the home, while % Occ refers to the percentage of time the home was occupied by at least one person (for the days released).
