PAVEMENT MARKER RECOGNITION DEVICE, PAVEMENT MARKER RECOGNITION METHOD AND PAVEMENT MARKER RECOGNITION PROGRAM

摘要

[PROBLEMS TO BE SOLVED] It is an object to provide a pavement marker recognition device that recognizes a pavement marker precisely even in the case where there are things on a pavement which are difficult to recognize only from tones or color information in a video image such as a ripped-off pavement marker and a shade similar in shape to a pavement marker. [MEANS FOR SOLVING THE PROBLEMS] A pavement marker candidate extraction means (12) extracts an image region having a characteristic similar to a pavement marker as a pavement marker candidate region from a video image picked-up by a camera mounted on a car, a road shape analysis means (11) analyzes a road shape from the video image picked-up by the camera mounted on the car, a pavement marker verification means (14) judges if the road shape analyzed by the road shape analysis means (11) and the pavement marker candidate region extracted by the pavement marker candidate extraction means (12) are in correspondence relationship as shown in the road shape-pavement marker correspondence table and, based on the judgment result, recognizes that the pavement marker candidate region is a true pavement marker.
