Abstract

When line structured light is used in 3D measuring with wide view field, the extraction of light stripe center becomes difficult because of the complex image background and non-uniform illumination. A line structured light center extraction method based on peak intensity is proposed in the paper. The peak intensity value of every pixel is calculated and the image is segmented according to the threshold related to the peak intensity, thus the structured light stripe center is extracted. Line structured light stripe images with wide view field have been processed by the proposed method. The experimental results indicate that our proposed method extracts the line structured light stripe center accurately when the background is complex, the illumination is non-uniform and the view field is wide.
