How to evaluate chamfer distance on dtu datastet?

[leo-frank]

DTU dataset provides groundtruth point clouds, LevelS2FM also generates mesh. I wonder the way that you evaluate mesh quality.

From my point of view, the process is compromised by 3 steps:

• first step is to sample points from generated mesh;
• secondly, aligning sampled point clouds with DTU ground-truth point clouds (this alignment including 3 parameters, rotation, translation, and scale) . I guess this step is implemented with open3D.registration ?
• lastly, compute chamfer distance between point clouds

Is my understanding correct? Can you provide corresponding codes of evaluating mesh quality ?
