The model uses the YOLO target detection algorithm to obtain the pixel position of the target ROI region in the image coordinate system, and then converts the pixel position to the world coordinate system by using the vertical and horizontal field of view angles of the camera and the camera resolution. Based on the camera mounting height and tilt angle, the distance between the target and the camera vertical point is calculated and compared with the preset defense zone distance and the model switching distance to determine whether the target needs to be detected for abnormal human behaviour and which abnormal human behaviour detection model should be used for detection. In addition to ranging the target without camera calibration, the model also divides the anomaly detection network for two different human features by the image distortion distance, which improves the convergence speed and recognition accuracy of the anomaly detection network.<\/jats:p>","DOI":"10.3233\/faia231251","type":"book-chapter","created":{"date-parts":[[2024,1,12]],"date-time":"2024-01-12T12:57:01Z","timestamp":1705064221000},"source":"Crossref","is-referenced-by-count":0,"title":["Simplified Monocular Ranging Anomalous Behaviour Detection Model for Security Monitoring Applications"],"prefix":"10.3233","author":[{"given":"Qing","family":"Liu","sequence":"first","affiliation":[{"name":"Bijie Power Supply Bureau, Guizhou Power Grid Limited Liability Company, Bijie City, Guizhou Province 551700, China"}]},{"given":"Yu","family":"Wu","sequence":"additional","affiliation":[{"name":"Bijie Power Supply Bureau, Guizhou Power Grid Limited Liability Company, Bijie City, Guizhou Province 551700, China"}]},{"given":"Jing","family":"Nie","sequence":"additional","affiliation":[{"name":"Bijie Power Supply Bureau, Guizhou Power Grid Limited Liability Company, Bijie City, Guizhou Province 551700, China"}]},{"given":"Yi","family":"Li","sequence":"additional","affiliation":[{"name":"Bijie Power Supply Bureau, Guizhou Power Grid Limited Liability Company, Bijie City, Guizhou Province 551700, China"}]},{"given":"Xiaohu","family":"Zheng","sequence":"additional","affiliation":[{"name":"Bijie Power Supply Bureau, Guizhou Power Grid Limited Liability Company, Bijie City, Guizhou Province 551700, China"}]},{"given":"Kang","family":"Liu","sequence":"additional","affiliation":[{"name":"Power Dispatch Control Centre, Guizhou Power Grid Limited Liability Company, Guiyang City, Guizhou Province 550000, China"}]},{"given":"Ping","family":"Wang","sequence":"additional","affiliation":[{"name":"Chongqing University of Posts and Telecommunications, Nanan District, Chongqing 400065, China"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Electronics, Communications and Networks"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA231251","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,1,12]],"date-time":"2024-01-12T12:57:02Z","timestamp":1705064222000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA231251"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,1,12]]},"ISBN":["9781643684802","9781643684819"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia231251","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,1,12]]}}}
