I have a camera which gives me images which are already rectified. I'm writing the ROS driver for it and I'm wondering what I should do with the camera_info message. Should I :
- Calibrate the camera and publish the intrinsic parameters in the camera_info message
- Calibrate the camera and publish the projection matrix but set the distortion parameters to 0
- Not calibration and set all the camera_info parameters to 0
For the record, I do not have access to the prerectified image, only the final result.
