LOOP_CLOSURE_DETECTION = True about colmap_slam HOT 5 CLOSED

Hi, do you still have the problem?

Hi!

Yes, it usually happens in a changing lighting condition when the algorithm fails to align the image.

Yes it is because the erroneous detection of a loop closure. For how it is implemented now I think you can only play with the commented options, but I do not think they will help a lot

The solution is in doing loop-closure detection with deep approaches, but not implemented yet in colmap-slam. For offline processing you could try to use this repo https://github.com/3DOM-FBK/deep-image-matching where for instance you can use deep image retrieval that is more robust for loop closure detection.
