When using the "exhaustive" method to perform matching, COLMAP generates N sparse models, always trying to improve upon the previous result. By default, the original code always selects the first model ("colmap/sparse/0"), which is not always the best one. The modification proposes a scan of the "colmap/sparse" directory to locate all models, analyze the number of frames found in each one, and then save the "transforms.json" file based on the best model.
