Which parameter will have an influence on the num of point in the `fused.ply` file? #1356

I am doing mesh reconstruction using colmap! I find that the mesh reconstructed by Poisson method has too many points, I think the reason is that there are so many points in the dense point cloud. Is my thought right? If so, could you tell me Which parameter will have an influence on the num of point in the fused.ply file? Looking forward to you insights! :)

Decreasing max_image_size or increasing min_num_pixels should result in fewer 3D points.

I appreciate it!

Hi @tsattler, Did you mean --SiftExtraction.max_image_size for max_image_size? What is the min_num_pixels? Could you provide some details? Looking forward to your reply!

I was referring to the parameters of stereo_fusion. For details on how the parameters work, you can have a look at how they are used in the code.

Thanks
