Trimesh model and model ICP registration (Python version)

1. Introduction

The registration of the model and the model in trimesh is still essentially the registration of the point cloud and the model, which is the same as that adopted in CloudCompare. First, it will sample the source model, convert it into a point cloud, and then use what we mentioned before: Trimesh point cloud and model ICP registration (Python version) to achieve the model-to-model registration allow.

Two, implement the code

icp_mesh_and_mesh.py

import trimesh
import numpy as np
from tkinter import filedialog
