hi Nutan,

the bumblebee2 node contains a bug when setting the CameraInfo on diamondback.

to fix this problem you will need to edit 2 things in the file: "bumblebee2.cpp" the first thing that needs to be done is to resize left_cam_info_.D (left_cam_info_.D.resize(5);) and right_cam_info_.D (right_cam_info_.D.resize(5);)

the second thing that needs to be done is to set the camera info distortion_model to plumb_bob. if this isn't done stereo_camera_proc wont be able to process the image. (right_cam_info_.distortion_model = left_cam_info_.distortion_model = "plumb_bob";)
