Hi,
the depth image is simply he disparity image between the projector and
the camera. So if you want to see the output use 'rosrun image_view
image_view image:=/camera/depth/image_raw'.
Even then you will see just a binary image. The best way to visualize te
output is to use rviz and display the pointlouds with according RGB
values.
