Pavement marker recognition device, pavement marker recognition method and pavement marker recognition program
Abstract:
A pavement marker recognition device for recognizing a pavement marker accurately is provided, the device being capable of recognizing an object even when it is difficult to be recognized only from tones or color information. A pavement marker candidate extraction unit extracts an image area having a feature similar to that of a pavement marker from an image captured by a car-mounted camera as a pavement marker candidate area, a road shape analysis unit analyzes the road shape from the image captured by the car-mounted camera, and a pavement marker verification unit determines whether the road shape analyzed by the road shape analysis unit and the pavement marker candidate area extracted by the pavement marker candidate extraction unit are in a correspondence relationship indicated by a road shape and pavement marker correspondence table, and based on the determination result, recognizes the pavement marker candidate area as a true pavement marker.
