Fail to reproduce COLMAP results on NVIDIA Dynamic Scene

[Szy-Young]

Hi @gaochen315 , first very thanks for open-sourcing this great work!

When I visualize the provided COLMAP results on "Truck", I find the moving truck is also reconstructed (red circle in the figure below). This is strange, since it should have been filtered out by "background mask", right?

I follow the suggested COLMAP pipeline (https://github.com/gaochen315/DynamicNeRF#train-a-model-on-your-sequence) to estimate camera poses by myself, and got the following results

The problem is, my estimated camera poses are not very correct (We know this dataset is captured by 12 cameras stacked on 2 levels). Therefore, I wonder if I should set some parameters specially. Do you have some special settings when applying COLMAP on NVIDIA Dynamic Scene dataset?

Thank you again and looking forward to your reply!
