Abstract
Accurate extraction of laser fringe center line is a key step in online structured light vision measurement system. When there are too many pixels in the picture, the traditional Steger algorithm can not quickly extract the laser fringe center line. Therefore, a method of extracting the center of laser fringe based on Steger algorithm is proposed. In this method, firstly, the threshold method is used to segment the optical strip region, then the expansion algorithm is used to find the continuous optical fringe, and finally find the center of the light strip with Steger algorithm. Experimental results ompared with the classic Steger algorithm, the speed of optical strip extraction is improved.
