Video Contrast Visibility Detection Algorithm and Its Implementation Based on Camera Self-calibration
基于摄像机自标定的视频对比度能见度检测算法与实现

Because trandition meteorological sensor’s range is limited and hard to be erected, video detections require good external conditon and are easliy effected by nosie. A new method of detection of visibility is proposed based on camera self-calibration. And a system of visibility detection is constructed. The camera self-calibration, wavelet transform, video contrast detecting model, curve fitting is used to overcome disadvantages of tradition detections algorithms at distance, targets, noise and stability. Now the system has been used on 1/5 of Jiangsu’s high-ways. The errors of result conform to national and foreign standards.
