Abstract

A traffic lane recognition system is provided for assisting a vehicle to analyze the left and right hand edges of a traffic lane, and a vanishing point, which comprises: an image processing unit, a detection unit of an area of emphasis, a recognition unit, a tracking unit and an evaluation unit. The detection unit of an area of emphasis can adjust the size of the area of emphasis. The image processing unit can pick up the original image from the driveway, and applies an edge-detection process to an original image from the area of emphasis to obtain a contour image. The recognition unit can identify the vanishing point and the left and right hand edges of a first input image, and then the tracking unit can base on the vanishing point of the previous image to trace the vanishing point and the left and right hand edges of the current image. The evaluation unit assesses the validity of the tracking unit to determine the necessity of further tracking, and outputs a proper result.
