<P>PROBLEM TO BE SOLVED: To accurately detect a widely scaled moving body including a vehicle, pedestrian, and bicycle on an intersection by using a reflection mirror (curve mirror) existing at the intersection with a simple system. <P>SOLUTION: A moving body detection system 11 for vehicle is equipped with: an in-vehicle camera 12 which photographs a reflection mirror 1; and a detection device 13 for detecting another vehicle V2, pedestrian, and bicycle or the like which is trying to enter an intersection on the basis of the video data of the in-vehicle camera 12. The detection device 13 is installed with: a video processing part 14 for analyzing the video data of the in-vehicle camera 12; an arithmetic part 15 for calculating the area ratio of the reflection mirror 1 to the moving body V2 projected on the reflection mirror 1 on the basis of the analysis result of the video data; a control part 16 for detecting the approach of the moving body to the intersection when the area ratio is increased; and an alarm part 17 for responding to an alarm command from the control part 16. When the approach of the moving body V2 is detected, a head lamp 3 irradiates the moving body with a passing light, and a buzzer 4 issues an alarm sound to the driver of a self-vehicle V1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
