Abstract

The traditional method of line laser stripes extraction is to binarize the image taken by cameras with a threshold value, but the size of laser lines in different color areas are obviously different because the line laser is absorbed by different colors of the parts to be measured to different degrees. For some regions with similar color to the laser, the traditional laser fringe recognition method cannot even identify the laser line, which results in the serious vacancy of the points cloud obtained by linear structured light scanning in some regions. An adaptive threshold method for laser fringe extraction is proposed in this paper. A modified HSV space is firstly proposed and the characteristics of the laser stripes on different colors of cardboard based on the modified HSV space is analyzed. Then a new image with high contrast through the quantized characteristics of the stripes is synthesized; Finally, the neighborhood filtering method is used to perform filtering and the Steger method is employed to extract the center of the laser stripe. Experimental results show that the method proposed in this paper can better segment the laser fringe from the background than the traditional algorithm, which lays a good foundation for the calculation of laser fringe center and hence to improve the measuring capability of laser structured light.
