摘要

设计了一种从机载激光雷达图像中提取直线边缘的方法。该方法首先使用中值滤波器对锯齿状边缘进行拉直，然后使用最小平滑处理的梯度算子对边缘进行检测。最后，利用梯度方向提取边缘。提取的边缘是直的，也有准确的位置。

Straight Edge Extraction from LiDAR Images

A method is designed to extract straight edges from airborne LiDAR images that usually show zigzagged edges. The method first uses a median filter to straighten the zigzagged edges and then uses a gradient operator with minimum smoothing processing to detect the edges. Finally, edges are extracted with the help of the gradient directions. Extracted edges are straight and have accurate locations too.
