Review of techniques for 2D camera calibration suitable for industrial vision systems

Abstract

In camera calibration the goal is to determine a set of camera parameters that describe the mapping between 3-D reference coordinates and 2-D image ones. Correction for image distortion in cameras is an important topic in order to obtain accurate information from the vision systems. A review of calibration techniques for the vision systems is presented among the different methods for camera calibration found in literature. The advantages and limitations of these techniques are also discussed. This work analyzes the techniques that can be useful in modern industrial contest with the aim of knowing the effective distortion of the lens and the possibility to determinate the measurement uncertainty of the vision system.
