Abstract: Aiming at the safety supervision of power operation site, a research is carried out on personnel intrusion detection. It is proposed to use the histogram of oriented gradient (HOG) and support vector machine (SVM) for full frame personnel detection, and then the OpenCV-based image processing technology is used to determine any personnel intrusion into the alert area. Through the images of the work site captured by video monitoring equipment, the above-said methods are used to identify the on-site personnel and their dangerous behaviors in real time, and to issue an alarm signal. The experimental results show that the accuracy of the detecting results reaches 92%, and the automatic safety supervision of power operation site is realized, which greatly improves the safety level of the power operation site.
