Efficient generic calibration method for general cameras with single centre of projection [PDF]

, 2007
Generic camera calibration is a non-parametric calibration technique that is applicable to any type of vision sensor. However, the standard generic calibration method was developed with the goal of generality and it is therefore sub-optimal for the ...
