| 摘 要： | 采用畸变-2D标定板的方法进行摄像机标定,基于多项式摄像机模型,使用图像投影描述为泰勒级数展开的标定方法,并通过非线性最小二乘拟合的方法求解得到相机的内外参数,对其方法进行了扩展和优化。实验结果表明该标定方法可以应用于广角、鱼眼以及折反射图像系统中,并能够获得较高的标定精度。

| Abstract: | In this paper, the camera calibration is carried out by using the distortion-2D plate based on the polynomial camera model. The method of image projection is described as the Taylor series expansion and the camera''s internal and external parameters are got by nonlinear least squares Method. In this paper the method is extended and optimized. The experimental results show that the calibration method can be applied to wide angle, fish eyes and catadioptric image system, and can obtain high calibration accuracy. |
