| 摘 要： | 线激光带边缘检测是机器人视觉系统处理的重要过程。由于激光带亮度不均匀,边缘不规则,造成传统边缘检测困难。为此,本文提出一种检测线激光带边缘的新方法,首先用Canny边缘检测算法初步筛选边缘点,再利用统计跳变回归分析判断边缘点和它的边缘方向,最后利用格式塔理论拟合边缘直线。实验结果证明,这种方法能有效地检测到线激光带的边缘,提高了检测的精度和速度。

| Abstract: | Edge detection of line laser strip is an important process of the robot vision system. Uneven brightness of the laser strip and edge irregularity result in the traditional edge detection difficult. This paper introduces a new method for detecting the edge of the line laser strip. Firstly, the Canny edge detection algorithm is used to select the possible edge points. Then the statistical jump regression analysis is used to judge the edge point and its edge direction. Finally, the edge line is fitted by the Gestalt theory. The experiment results show that this method can powerfully detect the edge of the line laser strip, and improve the accuracy and speed of edge detection. |
