Image Processing of the Hook on the Catenary Based on Machine Vision
In this paper, the idea loading and unloading workpiece on catenary based on machine vision has been proposed, for the feature of the hook on catenary, we first used gray-scale transformation, used a variety of edge detection operators to detect the image edge, then combine prewitt edge detection operator and Otsu to segment the hook image, the result shows that this method can extract the image edge of hook effectively, lay a good foundation for loading and unloading workpiece automatically.
