Because of the low calibration precision caused by reflector distortion in catadioptric vision systems with conic mirrors, we proposed a double distortion correction model based on the panoramic image rectification. The lens distortion and the reflector distortion are analyzed independently in the mathematic model of the double distortion correction. Moreover, the modified model in this paper added the trigonometric functions into the polynomial model to solve the combined distortion. Additionally, extensive experiments, both simulative and real data, have been carried out and show that the proposed model achieves comparable measurement accuracy in contrast with the traditional distortion method.
由于在带有圆锥镜的折反射视觉系统中，反射镜畸变会导致校准精度较低，我们提出了一种基于全景图像校正的双畸变校正模型。在双畸变校正的数学模型中，分别对镜头畸变和反射镜畸变进行了分析。此外，本文改进后的模型在多项式模型中加入了三角函数来解决组合畸变问题。另外，我们进行了大量的模拟实验和实际数据实验，结果表明，与传统的畸变校正方法相比，所提出的模型具有相当的测量精度。
