Abstract :
In real operation of computer visual 3D construction system, the type of camera being used is uncertain, thus the nonlinear distortion degree of camera lens are various. Therefore, a new flexible camera calibration method should be found, which can choose proper calibration method according to different cameras. A kind of method meeting this demand is put forward in this paper. This method has several key parts: the choice and design of standard graphics, estimation of degree and type of nonlinear distortion and judging standard. In testing the proposed methods, satisfactory results are achieved in real data experiments
