一种基于机器视觉的材质边缘检测算法

A Material Edge Detection Algorithm Based on Machine Vision

提出了一种基于机器视觉的智能的边缘检测算法,可单独识别同一图像中不同材质之间的边缘.不同材质的物体具有不同的表面光学特征,在HIS色彩空间内,其像素的H、I、S三个色彩分量的分布曲面满足不同的规律.该算法在一定的范围内计算属于该范围的像素的空间分布规律是否一致,若不一致,则该范围内存在不同材质的物体,进而计算不同材质物体的边缘.实验证明该方法简单、有效,解决了边缘检测中按材质计算边缘的问题.

To find the edge between two different materials,an intelligent edge detection method based on computer vision is proposed.Every kind of material has its own optical character.In the HIS color space,the pixels in the same material surface locate with the same rule.If pixels in a window locate with different rules,the window contains different materials.Experiment proved that the method is simple,effective,to solve the problem about finding an edge between different materials.
