Utilizing polygon segmentation technique to extract and optimize light stripe centerline in line-structured laser 3D scanner
作者：
Highlights：
• Based on that light stripe׳s contour is approximately parallel to its centerline.
• Segment light stripe into parts by contour polygon representation.
• Interior included angle is defined to trim open light stripe׳s polygon and contour.
• Piecewise polynomial fitting and self-adaptive interpolating strategy are adopted to generate optimized centerline points.
• Extensive experiments validate the method׳s performance including accuracy, robustness and speed.
