Image recognition apparatus and image recognition program

摘要

An image information acquisition unit acquires image information of a plurality of frames of images sensed at regular intervals, each image including a road surface of an area close to a vehicle. An image recognition unit performs an image recognition process to detect a leading end and a trailing end of a lane mark included in a detection area defined in each frame of the image information. A distance detection unit detects the distance from one of the ends of the lane mark to the other on the basis of the speed of the vehicle and the number of frames between a frame in which one of the ends of the lane mark is detected and a frame in which the other end of the lane mark is detected. A lane mark type determination unit determines the lane mark type of the lane mark on the basis of the detected distance.
