| 摘 要： | 以高斯模糊的仿真图像和薄片零件图像为评价图像．分别用Roberts算子、Sobel算子、Prewitt算子、Kirsch算子、Laplacian算子、LOG算子、数学形态学边缘检测方法进行边缘检测，对边缘检测结果进行了深入分析，对算法的边缘定位精度、抗噪声能力和计算时间进行了比较。数学形态学边缘检测方法能获得单像素宽连通的轮廓，检测时间分别为0．0521s、0．457s。选择数学形态学边缘检测方法作为薄片零件尺寸机器视觉检测系统的边缘检测方法是合适的。

| Abstract: | The Gaussian blurred simulation image and thin-sheet part image were taken as evaluation images, and the edge detection is done with Roberts operator, Sobel operator, Prewitt operator, Kirsch operator, Laplacian operator, LOG operator and mathematical morphology edge detection method. The results of edge detection were analyzed deeply, and the edge location accuracy, noise resisting ability and calculation time of each algorithm were compared. The single-pixel width connected contour was acquired with mathe... |
