Abstract
Aiming at the real-time 3D reconstruction of large-format components, this paper proposes a method for extracting the centerline of laser stripes against ambient light interference. The Zhang-Suen thinning algorithm is optimized to effectively retain the data information of the laser fringe endpoints. In the process of fitting the centerline of the la-ser fringe with the least square method, a method of extracting the region of interest is proposed. Through the anal-ysis of experimental data, this method effectively improves the anti-interference ability of the algorithm, is suitable for more scanning occasions, and reduces the conditional limitation of using laser three-dimensional scanning in the industrial measurement process.
