Abstract: In order to solve the high complexity and the insufficient robustness of existing reconstruction methods, a blackbox camera calibration method on the basis of the mapping transformation was presented. According to the linear mapping model between the imageplane reference frame and the objectspace reference frame, the matrix equation to calibrate the camera was used. Comparing with the traditional methods, the method only needs one planemodel image to reduce the quantity of the feature points and the template, and simplifies the calculation. In the experiment the preprocessings, such as image filtering and Harris operator corner detector, etc., were used to get feature points quickly and realize the mapping transformation of camera parameters. The error estimate function was established to compare the proposed method with Tsai calibration algorithm. The experiment results show that the method is characterized by good stability, high precision and algorithm simplicity.
