Hello,
I have done both tutorial for the kinect mapping with an Asus Xtion pro live.

(http://wiki.ros.org/rtabmap_ros/Tutorials/HandHeldMapping and https://github.com/introlab/rtabmap/wiki/Kinect-mapping).

When I use the tutorial on github (no launch file), the mapping is very accurate and the odometer doesn't get lost. But when I try to reproduce the same thing with rgbd_mapping.launch the odometer get loss unless I move very slowly and the map is less accurate.
I try to change the parameters and check the difference in the window "preference" but I cannot find an explication which could explain that difference.

What could explain that difference?

Thank you.
