Hey Mathieu,
I have pulled the most recent version of Rtabmap and some other libraries (e.g. latest opencv 3.4) and found that the SIFT features exported via the Bundler exporter are 64-dimensional instead of 128. Does this change come from opencv or can the length be set in rtabmap somewhere?
Edit: ok, nevermind, it's probably the opencv version. I think 3.4.11 already contains SIFT without opencv_contrib package and without the nonfree flag. Rtabmap also detects it and allows selecting it in the settings, but during runtime some check prevents SIFT features from being extracted.
