Physical Intrusion Detection System Using Stereo Video Analytics

Physical Intrusion Detection System (PIDS) detects unwanted elements (person or object) entering into a restricted zone. There are various single-camera solutions for surveillance available in the market. The key problem with video analytics based solution is false alert. With the addition of dimensional information of intruding object, it is possible to reduce false alertswithout compromising an increase in true negative. We propose deployment of a pair of cameras in stereo configuration for facilitating dimensional measurements. This method also will be useful to detect and characterize flying objects entering in restricted zone. Experiments were conducted on various scenarios emphasizing the usability of stereo in surveillance.
