I'm trying to calibrate a stereo camera with one of the cameras upside down, but the results are far from correct (rectified image is distorted). The images are being published using cv_camera, which apparently does not give an option to flip the image. Is there a way to solve this without an intermediate node such as image_rotate?

To clarify when you say upsidown do you mean rotated 180 degrees around the lens axis or mirrored vertically? The latter is an improper rotation that the calibration settings will be incapable of compensating for.

It is rotated 180 degrees around the lens axis. I decided to use this configuration to increase the baseline as the lens is located at the extremity of the camera body (C310).
