Abstract
Recognition rate performance is prevented from dropping in executing image recognition processing on a moving object passing a surveillance area. A video surveillance apparatus includes a preprocessing information generating section that obtains position of a recognition processing region to be an object of image recognition processing and installation position of a camera, computes the positional relationship between the position of the recognition processing region and the installation position of the camera, and computes preprocessing information representing the positional relationship, a recognition parameter computation section for computing recognition parameters (coordinates of the recognition processing region in camera image) used for image recognition processing, based on the ratio between an actual value and a distance in an image captured by the camera with reference to the preprocessing information, and an image recognition processing section for executing image recognition processing on a surveillance object passing the recognition processing region, using the recognition parameters.
