Empty Octomap in RGBDSLAM
I am using rgbdslam_v2 with the Intel Realsense R200 on ROS Kinetic. It seems to be working fine and I am getting a point cloud in the RGBDSLAM GUI. However, when I turn off the cloud display to view the Octomap, it seems to be empty. Saving the Octomap also just saves an empty Octomap. I have tried enabling online octomapping and running the Point Cloud Occupancy Filter menu item (which I am not quite sure how is supposed to be used - is it for generating the Octomap when online octomapping is disabled?), but to no avail.
Is there something I have missed?
Thanks.
The voxel filter is meant to geometrically downsample the clouds. I guess it should better not be used with octomapping, might work though. Have you set the "store_pointclouds" parameter to false? It is true by default.
