Octomap showing only the current point cloud
Hi, I am trying to use the octomapserver libraries to build a map from a velodyne vlp-16 lidar. I give the input pointcloud in the baselink frame and then I launch the octomapmapping.launch file. But, when I visualize the octomappointcloudcenters topic in rviz, I see only the current input point cloud as the output and I am unable to see the map. However, I the new point cloud seems to be added to the previous point cloud for a short time and then the old point cloud disappears. Can anyone tell what mistake I am making? I do not understand the significance of using tf to change the frame to /map. Do, I have to use the map frame?

I asked a similar question on octomap google group here. It seems like we are in the same boat. Contact me at chukcha2 at yahoo dot com and I can share my experience so far.

Could your point cloud visualization be affected by the
rvizdecay time setting?Asked by joq on 2016-04-05 09:19:34 UTC
