OBJECT DETECTION DEVICE, OBJECT DETECTION METHOD AND OBJECT DETECTION PROGRAM

摘要

The present invention accurately detects an object from a video image where large distortion of an image may be generated for covering a wide field of view. An object detection device 1 that detects an object from a camera image captured by a camera having a wide field of view and causing distortion varying according to a position in an image includes: a candidate area selection unit 10 configured to select candidate areas for detecting the object from the camera image, and generate candidate area information identifying the candidate areas, and positional parameter information indicating distances from the center of the camera image to the candidate areas; and an object detection unit 20 configured to select, on the basis of the positional parameter information corresponding to the candidate areas, an object detection system used when detecting the object from the candidate areas, rotate the candidate areas with respect to the center of the camera image in order to unify directions from the candidate areas to the center of the camera image to the same direction, and detect whether or not the object exists in each of the candidate areas, the directions of which being unified.
