Hi all!
My task is to use hector_elevation_mapping package + point cloud data to produce an elevation map. Basically, the elevation map is represented by a 2D grid map storing a height value with a corresponding variance for each cell.
However, I am unable to do so even after I publish/subscribe the correct node (I assume). Nothing seems to be a problem while running the process, just that I can't get the result of elevation mapping.
This is my rqt_graph, hopefully everything is ok: [before elevation works.png](/upfiles/1437644431509610.png)
What happened in RVIZ is that 2D mapped area can be shown (with hector_mapping) and depth image of the camera produced. I have already set PointCloud2 topic to the relevant one, /camera/depth/points_xyz.
RVIZ display: [depth image rviz.png](/upfiles/14376447258357702.png)
Thanks for any help!
