| Summary: | This paper provides a classification of calibration methods for cameras and projectors. From basic homography to complex geometric calibration methods, this paper aims at simplifying the choice of the methods to perform a calibration regarding the complexity of the setup. The classical camera calibration methods are presented. A comparison gives the pros and cons for each method. For the projector calibration, the homography, the structured light methods and the geometric calibration are presented. Every general approach for the projector calibration is studied and the limitations of each method are given. Each approach is described through the main reference method. A classification of each projector calibration approach is given.
