Black boundaries in some cases of Shiny dataset #49

Closed Totoro97 closed 2 years ago

Totoro97 commented 2 years ago

Hi, thanks for your great work!

I found there are some black lines in the boundaries of some images, in the Shiny dataset (for example, CD):

After I resize the image to the target width (1008), the black line still exists:

Could you help figure out the reason behind this issue? I would like to know if I should remove the boundary pixels during training (and also in testing).

Thank you very much!

My guess is this black border comes from COLMAP's undistort procedure.

We didn't handle this problem. but I think it should be fine to mask the border out and specify this problem on your report I guess.

If you have a better method for undistort or want to use different padding instead of zero padding to remove the black border. We also provide an image in the images_distort directory.
