image_proc vs image_raw
Hi, all!
I am quite misunderstood with playing imageview node and my mono camera. If I pass imagerect it shows very distorted image, whereas imageraw looks much better than imageproc. If I calibrated camera, I will need to use imagerect topic messages, right? Not imageraw, 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.
