custom_data have so many floaters #96

Hi, How to improve performance when training custom_data? There are so many floaters and blurry part.

Hi,

  1. it likely depends on the data. Exposure changes, dynamics (these are not modeled in this released code), and strong specularities can lead to lots of floaters
  2. Our original data processing code as released uses COLMAP undistort, and I recently found that that leads to errors and blurriness. Adding --noradial to the COLMAP script might help as a workaround. I have not implemented more advanced camera models in this codebase
  3. near_clip, although custom.json has it pretty high already that sometimes leads to issues
