Abstract

A description is given of an unmanned intrusion detection system for power stations or substations that detects trespassers in real time, both indoors and outdoors, and is based on image processing. The main part of the system consists of a video camera, an image processor, and a microprocessor. Images are input from the video camera to the image processor every 1/60 s, and objects that enter the field of the image are detected by measuring the changes of the intensity level in selected sensor areas. The shapes and locations of active sensor areas can be determined based on detection application, using techniques tailored to the application. Noise removal filters prevent spurious detections. High detection sensitivity is guaranteed under any environmental condition. The system configuration and the detection method are described. Experimental results under a range of environmental conditions are given.<>
