摘要
本文提出了一种新的摄像机标定方法,首先对含有畸变的二维图像进行矫正,再应用矫正后的图像对摄像机进行线性模型标定。给出了标定方法的理论依据和求解过程,并将其与线性标定方法和两步法进行了对比实验。实验结果表明:该方法无需预标定过程,即可迅速、方便地对摄像机进行标定,并且具有较好的精度。
A new technique for the camera system calibration was proposed firstly, the 2-D image with aberration was rectified, then, the rectified image was used to calibrate the camera system with the linear model. The theoretical basis and the solving procedure of the proposed calibration technique were presented, and the comparative experiments among the new method, linear calibration method and the two-step method were performed. The results showed that the proposed technique can quickly, conveniently and accurately calibrate the camera system without the need for the precalibration procedure.
