Reconstruction results are strange

I used the pretrained model in the repo with conmand python eval_rcmvsnet_dtu.py , and visualized the ply file of scan4 in the output directory, but the visualization results looked strange with some black parts, the visualization results of other scan have the same problem, as shown below,:

My mistake, I visualized the ply file in ply_local folder, the final fusion result is as follows, which is normal.
