The authors developed a compact system for finding intruders, by using a vision sensor with a fiber grating optical device (FG vision sensor). When this FG vision sensor was installed at the ceiling and a laser beam was projected onto the FG, a bright spots pattern was projected on the floor. The authors succeeded to realize a pilot system of good performance for detecting the person's volume, position and direction in a short time, by calculating the three-dimensional position of the translated spots. This paper describes the method of finding intruders using the FG and the configuration of the developed system. And we discuss the results of the experiment which we performed to verify the effectiveness of the proposed method.
