Thanks man!  I built from git both rtabmap_ros and rtabmap and tested obstacles detection and rgbd odometry - both works! :)  obstacles detection runs through many situations where ground is not visible!

visual odometry works great, but still lose tracking when robot travel through a particularly narrow and featureless passage way - and it makes sense.  but after that particularly difficult area odom continue to stay 0, even when the area has many features.  I can see why that is - visual odometry has lost some continuity, but since many SLAM only look at short-term changes in odom, would there be a way to make it resume after area of featurelessness?
