Hi guys,
I run the ''demo_robot_mapping.launch'' with the ''demo_mapping.bag'' , on ubuntu computer ,the result is fine . But on the VMware ubuntu ,the map is wrong , the proximity detections seems not working , then I play the rosbag with speed=0.6 ,but the result is wrong ,it's not the CPU problem;  I can't find out what's the problem ,  as both system are installed the rtabmap by ''apt-get install ros-kinetic-rtabmap-ros'' .....  looking forward for your help  , thank you !!!

Hi,

looks like the proximity detections worked (there are yellow pixels in the grid map) until the first turn on left of the map when coming back. I don't see why there would be a difference between the setups. I cannot unfortunately test the WMWare +16.04+kinetic binaries (with my limited time). If you can reproduce the same problem with VMWare+20.04+noetic, I could take a look.

Note that looking at the old demo launch file from kinetic, the Icp/CorrespondenceRatio may be high: https://github.com/introlab/rtabmap_ros/blob/82bcecdd454e3900eef91fb7035718331ad1e495/launch/demo/demo_robot_mapping.launch#L56

cheers,
