rviz camera view

Question

How do I set up a view in rviz to be the exact view from the camera's perspective? For Example: If you add the point cloud coming in from the kinect how do I set the view so I see the point cloud from the exact perspective of the kinect.

Answer 1

To see rviz from a camera perspective:

1. Have the RVIZ Displays Pane Open (View > Displays)
2. Click "Add" to add a new display type
3. "Camera" displays your camera image with RVIZ data overlayed, "Image" will just show the raw camera image.
4. When then new display shows up in the list, fill in your "Image Topic" (e.g. /kinect/image_raw)

You should now have a working image window with RVIZ data overlaid.

You can also change the alpha blending so that just the rviz data is visible, and not the actual camera frame
