摘要
激光雷达测量能见度是激光雷达的一个重要应用,水平能见度的反演在线性区的选取上存在的不确定因素制约了激光雷达的应用。本文根据激光雷达水平测量数据的特点,提出了一种迭代扩展算法确定水平测量数据的线性区,并进而反演水平能见度。该算法可以确定线性区的最大范围,并将非线性区排除出去。经实验验证表明,该算法能可靠地自动反演水平能见度。
The algorithm of retrieving the horizontal visibility based on lidar was developed in this paper. The horizontal measurement data of lidar exists a linear area which is difficult to ascertain. The algorithm firstly iterates in special data segment to fix on the linear area, then expands the area to both ends, and finally gets the longest linear area. The horizontal extinction and visibility can be retrieved through the final linear area. The results compared with Vaisala apparatus indicate that the iterative expanding algorithm could be used to retrieve the horizontal visibility.
