Depth map unreliable


When I run

rviz -d slamdunk_qsg.rviz

Everything looks basically right except that there is no depth image. The Depthmap display is in a Warning state, and Unreliable is on. If I turn Unreliable off, then I start getting depth images, although much of the image is black. Do I need to do some type of calibration?


I have the same kind of noisy depth map, and I’m wondering whether it’s preventing me from having a rich enough PointCloud2 (/pcl_xyz) in order to use octomap_server to filter the ground plane (which is determined thanks to a plane detection RANSAC-based algorithm). Anyone tried this kind of filtering before thanks to slamdunk generated PointCloud2 ?
