Matei,

I am having the same problem trying to make videre_stereo_cam package
working with Diamondback. I think I found the culprit in
stereo_camera_model.cpp in from_camera_info method. The first time you
run the camera fromCameraInfo(left, right) left_.fromCameraInfo(left)
returns true and the second part of the or statement is short
circuited so right_ is never initialized. If you split these into two
lines everything works as expected.
