REGULARIZATION METHOD FOR DETECTING LINE SEGMENT EDGES IN IMAGE OF NON-TEXTURED METAL COMPONENT

摘要

A regularization method for detecting line segment edges in an image of a non-textured metal component. The method comprises: calculating gradient values of respective pixels in an input image of a component; employing an LSD algorithm to detect preliminary line segments; and using distances and angle relationships between the line segments to connect discontinuous line segments. Thus, the invention detects complete line segments and avoids the problem of broken line segments when performing detection. The method is an improvement on LSD algorithms, and can be used to output complete line segments while also maintaining the fast speed of the LSD algorithms. Moreover, the method is applicable to both RGB images and grayscale images and so can meet the requirements of actual applications.
