Problem in Stereo fusion after doing patch match on geo-registered sparse reconstruction

[MandeepSingh396]

Hi,

I have some data for which I did sparse reconstructyion ans then geo-registred the data using the 'model aligner'. After that I am trying to implement dense reconstruction on the geo-registered data. I am able to undistort the images and do patch_match_stereo without any errors, but while I am running stereo_fusion it shows 0 points fused with the following warning.

Fusing image [1/3] with index 0 in 0.976s (0 points)
Fusing image [2/3] with index 1 in 1.031s (0 points)
Fusing image [3/3] with index 2 in 1.015s (0 points)

WARNING: Could not fuse any points. This is likely caused by incorrect settings - filtering must be enabled for the last call to patch match stereo.
Number of fused points: 0

I already checked and I know filter is enabled for the last call to patch_match_stereo. I am not sure what I am doing wrong. Any help here would be much appreciated. Thank you.

Have you looked at the reconstructed depth/normal maps after the patch match step?

I just checked it after your comment. The normal map is showing very few sparse points and depth map is just blank.
