Edge Detection Based on computer vision in geometrical measurement
Hongmei Lü · 2006
Base on the characteristics of edge detection,several typical edge detection methods are analyzed in detail.Methods for edge detection on computer vision in geometrical measurement and the software design of the system are stated.The method can be summarized as follows: First the image is smoothed using a Gaussian filter,then the local gradient and edge direction are computed at each point,then the edge points determined give rise to ridges in the gradient magnitude image,finally,the algorithm performs edge linking.The experiment results : In addition to detecting the desired features,the method also produced the cleaner map.
