demo_colmap.py ply file

[PAIGUI]

Hello, thank you for your great work. I found that there are some black dots in the point cloud obtained after demo_colmap.py, just as shown in the picture above. May I ask if this is normal? Is there a way to remove these black dots? Looking forward to your reply

Hi you just need to adjust to filter these points out. They are basically background points and should have very small conf
