摘要：[PROBLEMS] To provide a video analysis system that automatically detects anabnormality occurring in a monitoring area while using a PTZ type surveillance camerainstalled in a monitoring area such as on an outdoor road and suppressing erroneousdetection caused by changes in environmental conditions. It is to provide. An obstacledetection system includes a photographing means (101) for photographing a monitoringarea such as on a road at a single or a plurality of angles of view, and an object regiongenerated in the monitoring area from an image captured from the photographingmeans. Object extracting means (201) for extracting pixel values. The failure detectionsystem further divides the object region and pixel value acquired by the object extraction
means (201) into blocks based on the angle of view and the determination criteria set foreach position in the video, and local features Object recognition means (202) foridentifying the type of the object from the quantity, and obstacle detection means fordetecting the presence or absence of an obstacle generated in the video from theinformation on the object type acquired by the object recognition means (202) ( 204).[Selection] Figure 2
