摘要：Driver's visibility diminishes severely in rainy conditions at night. The glare on wet road surfaces causes this poor visibility. In this paper, we propose an image processing method that detects the glare on wet road surfaces by Using multiple onboard cameras. We also propose an image generating method that reduces the effect of glare. By Using our method, glare-reduced images can be obtained and by displaying these images on the monitor equipped in the vehicle, the number of traffic accidents can be reduced. The proposed method is based on the characteristic that the road plane has a common planar surface in multiple camera images. By Using this characteristic and a homography matrix, the glare can be detected. Experimental results obtained by applying the proposed method to real image data show its high performance.
