Hi, all!

I am quite misunderstood with playing image_view node and my mono camera. If I pass image_rect it shows very distorted image, whereas image_raw looks much better than image_proc. If I calibrated camera, I will need to use image_rect topic messages, right? Not image_raw, yes? Does it mean that my camera is not well enough calibrated?

When I run cameracheck.py it shows that my Reprojection RMS Error varies from 3 to 18 pixels. Is it bad?

3 to 18 pixels sounds bad. I haven't used cameracheck.py but I imagine it is similar to other tools that calculate reprojection error and you should be less than a pixel. You can tell visually- if straight lines don't look straight in image_rect then the cal is bad.
