Hi,
First of all, I have started to use RTAB-Map with an L515 to scan small environments and people on Windows10
It seems to be doing what I need very well, although I see on this forum that the typical use would be for much larger maps and for robots (and I am impressed by the possibilities I see).
Said that:
I am completely new to Rtab-Map and LIDAR scanning, and have two very basic questions.
1. On the 3D Map window, while the 3D Map is being constructed, I can see two paths that are drawn on the window. I figured out one of them is the ‘trajectory’, and I can deactivate it from being shown, but I cannot figure out what the other path is, and if I can stop it from being visible on top of the image.
2. When I press the stop button, the software stops responding and it takes quite a while before it starts responding again. I guess this is normal, as it is computing the Map, but was wondering whether there are some settings that will change the time it takes to do this computation.
Hope this makes sense, and that someone can give me some hints,
Thanks,
 Alain.
