摘　　要：针对智慧城市中道路交通能见度的观测问题,通过分析国际照明委员会定义的大气能见度公式,提出了一种道路能见度的观测算法。通过图像暗通道先验与辅助车道线检测相结合,设计出选定图像中某一车道线的起点和终点,分别计算出两点透射率,结合车道线长度即可求出大气消光系数,进而实现基于图像的能见度观测估计。实际测试表明该算法的有效性。To address the issue of observation of visibility on the urban traffic roads in intellectual city,based on the analysis of the formulas of atmospheric visibility defined by International Commission on illumination(CIE),an algorithm of visibility observation is proposed.By combining dark channel prior and auxiliary lane detection,designing a solution to find out the atmospheric extinction coefficient by selecting the start point and the end point of a certain lane line in the selected picture,calculating the transmissivity of the two points,and combining the length of the lane line.Finally getting the estimation of visibility observation.The data validation of the algorithm has been proven by practical test.
