Study of Tunnel Surface Parameterization of 3-D Laser Point Cloud Based on Harmonic Map

In the maintenance work of tunnels, images are often used to detect diseases, but collections of tunnel images are limited by the tunnel environment and working time. Three-dimensional laser scanning technology can acquire high-precision tunnel information efficiently, and the main problem to be sol...
