Hello,
I use COLMAP with PBA in GPU to SfM, but there is a problem. When the number of image increases to about 400, the reconstruction becomes bad and the global BA works for the first iteration then throws "alpha=NaN" in next iterations. Is this caused by the single precision convertion or bad reconstruction?
