Surface Reconstruction With Optimized Random Laser Plane Generated From Cylindrical Reference

A reconstruction approach is presented with a random laser plane and a cylindrical reference. A semi-cylinder reference with the known diameter is designed as the cylindrical-coordinate-system. The optimization function is provided by the parameterized re-projection errors of the feature points on the cylindrical reference, the laser intersection points on the cylindrical reference and the object. The reconstruction approach is tested and analyzed by contrasting the difference between the reconstructed value and the true value of the vernier caliper. The means of the root mean squares of the optimization and initialization are 1.36 and 1.44 mm, respectively. The experiments indicate that the approach with the random laser plane and the cylindrical reference is a reliable method for the 3-D reconstruction in the active vision system with the planar structured light.
