Float blur in render images #51

Closed LingyunWang closed 1 year ago

Really appreciate for your important job and share of the project ! I use data captured by Dji sport camera to reconstruct the scene, which are high quality!

But recently I move a fly camera around a unbounded scene, the rendered images have float blur! color_20000_008

I checked the camera poses (as below). Looks like no problem. 屏幕截图 2023-05-18 182635

All the data of images and camera poses are available: https://drive.google.com/file/d/1Zf36hdqAk1NI5u9ucJ7rQs2HBc3i1sIA/view?usp=sharing Looking forward to paying attention to this issue

Hi, I guess one of the main causes is incorrect camera poses. Could you try this cams_meta.npy file and train it again? I obtained it by hloc instead of traditional colmap SfM. If the results are better, I will add hloc SfM in this repo. Since the images here have some motion blurs, it would be challenging for pose estimation by colmap.

It bring great imporvement using new camera poses caculated by hloc ! Thank you very much!
