Traffic Lane Marking Line Recognition System for Vehicle
First Claim
1. A system for recognizing a traffic lane marking line for a vehicle comprising image photographing means for photographing a range including a road surface in a direction of travel of the vehicle;
- traffic lane marking line recognizing means configured to be capable of recognizing at least a traffic lane marking line in broken line on the road surface in a photographed image photographed by the image photographing means;
image compositing means for compositing a plurality of images photographed at different time points by the image photographing means to elongate the traffic lane marking line in the photographed images;
brightness detecting means for detecting brightness of the plurality of images photographed by the image photographing means; and
brightness correcting means for correcting the brightness, taking one image among the plurality of images as a reference, such that the brightness of the plurality of images are equal to each other; and
the image compositing means composites the plurality of images after the brightness has been corrected by the brightness correcting means.

Abstract
A traffic lane marking line recognition system for a vehicle includes an image compositing device which composites images photographed at different time points by a camera to elongate a traffic lane marking line such as a white line in the photographed image, the brightness of the photographed images is detected, the brightness is corrected, taking one image among the plurality of images as a reference, such that the brightness of the plurality of images is equal to each other, and the plurality of images are composited after the brightness has been corrected. By making the brightness of the images to be composited equal to each other, it becomes possible to recognize the traffic lane marking line accurately and unerringly.
