TRAVEL SECTION LINE RECOGNIZER FOR VEHICLE

摘要

In the traffic lane marking line recognition system for vehicle having traffic lane marking line recognizing means configured to be capable of recognizing at least a traffic lane marking line in broken line on the surface of road such as a white line in a photographed image photographed by a camera, and image compositing means (S10 to S16) for compositing images photographed at different time points to elongate the traffic lane marking line in the photographed image, the images are composited in a processing stage in such a manner that no change will be imparted to at least a shape of the traffic lane marking line in the photographed image in a traffic lane marking line recognition processing, specifically in a processing stage prior to edge detection (S12). With this, a distant traffic lane marking line is prevented from being chipped away when compositing the photographed images, thereby enabling accurate and unerring recognition of the traffic lane marking line.
