Camera Calibration: Geometric and Colorimetric Correction

International audienceThis chapter analyzes camera calibration from a geometric and colorimetric perspective. The first part of the chapter introduces the mathematical model that describes a camera such as position, orientation, focal, as well as its applications such as 3D reconstructions. It analyzes different geometric processes for stereoscopic images such as corrections of radial distortion as well as image rectification. The second part of the chapter focuses on colorimetric models relating to digital acquisition systems. It demonstrates how to characterize a colorimetric camera and then analyze different elements involved in color correction for images taken from a system of cameras
