: Introduction of two kinds of classical camera calibration accuracy assessment methods: Tsai made the measurement accuracy of 3-dimensional world of norms and Weng raised NSCE, NCE criteria. On this basis, a checkerboard grid on the length of calibration accuracy assessment methodologies. The method is measured through the intersection of a number of checkerboard grid of side length and the actual side length of the error in terms of quantity of camera calibration accuracy and be able to compare the image to describe the accuracy of calibration results.
