Camera calibration is probably the most common topic taught and needed in computer vision. Yet I don't think most of the people know how to properly calibrate a camera:
- blurry images
- same viewpoints
- calibration board printed on a sheet of paper
- bad illumination
- ...
There are also some misconceptions I believe. For instance:
- I don't think taking fronto parallel calibration views is a good think with the internal calibration method, see:
- people usually takes lots of images while I don't think it is really needed, with the idea that the more the images we have, the better is the quality of the parameters estimation
This page has some camera calibration advices: https://www.dlr.de/rm/en/desktopdefault.aspx/tabid-3925/6084_read-9196/
An interactive tool to assist the user about how to correctly position the calibration target in front of the camera could be an idea for a potential GSoC student? Some potential features for the calibration tool:
- support different calibration patterns?
- mono + stereo calibration?
- assist the user for the next board viewpoint to use?, show where to position the board in the image
- don't use blurry images?
