Paper Abstract

This essay proposes a method for camera calibration. This method calibrates camera's all intrinsic parameters and extrinsic parameters step-by-step under the condition of considering the first order radial distortion. Compared with Tsai's two-stage method, this method only needs to use a coplanar target and can calibrate the image center and the scale factor. It also introduces a new distortion model and then can completely calibrate camera linearly, avoiding the trouble and the instability of non-linear optimization. It's simpler. Then, this essay introduces a computing model of three-dimensional reconstruction of the two cameras' system, and proves that this calibration method has high accuracy after the three-dimensional reconstruction.
