一种机载激光雷达距离图像的自适应边缘检测方法

An Adaptive Edge Detection Method for Range Image of Light Detection and Ranging

针对Canny算法处理机载激光雷达距离图像时出现过多伪边缘、丢失弱边缘信息以及阈值确定方法缺乏客观性等不足,文中提出一种自适应的边缘检测方法。实验结果表明,改进方法能克服以上不足,有效地进行边缘探测。

In view of deficiencies of Canny algorithm in processing range image of light detection and ranging, such as generating many false edges, losing weak edges and lacking objectivity in threshold determination, an adaptive method is proposed in this paper. The experimental result shows that, it can overcome the disadvantage of Canny algorithm and detect edges effectively.
