摘要
针对现有能见度检测方法复杂度高和检测精度低的问题,提出了一种基于监控图像的道路能见度检测方法。首先,通过暗亮原色先验理论求取暗亮原色的透射率;然后,利用自适应去雾权值和自适应滤波窗口优化大气光值和大气透射率,将车道线首尾端点的透射率与优化后的暗亮原色透射率一一对应;最后,结合车道线首尾端的距离计算大气消光系数和能见度。实验结果表明,本方法可在100~600 m内实现高精度检测,相对误差小于10%。相比其他方法,本方法的检测效率更快、精度更高且更容易实现。
Abstract
In view of the high complexity and low detection accuracy of the existing visibility detection methods, a road visibility detection method based on monitoring images is proposed in this work. First, the transmittance of dark and bright primary colors is obtained by using the prior theory of dark and bright primary colors; then, the atmospheric light value and atmospheric transmittance are optimized by using adaptive defogging weight and adaptive filtering window, and the transmittance of the front and rear ends of the lane line is one-to-one corresponding to that of the optimized transmittance of dark and bright primary colors; finally, the atmospheric extinction coefficient and visibility are calculated by combining the distance between the front and rear ends of the lane line. Experimental results show that the method can achieve high precision detection within 100--600 m, and the relative error is less than 10%. Compared with other methods, the method has faster detection efficiency, higher accuracy and easier implementation.
