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.
