一种简易的基于矩形靶标的相机定位方法

针对交通视频监控的双目视觉相机定位问题，使用相机成像的仿射原理和光学透镜成像原理，建立相机像点与原像之间的非线性数学模型。采用外公切线法确定圆心的像，由光学成像几何关系得到非线性等式模型，应用MATLAB求解模型。从误差分析中得出模型相对误差小于0．16％，精度较高。模型建立后，整个标定过程不需要人工干预，可以自动进行标定，实用性好。

Simple camera calibration method based on rectangle target

According to dual-camera calibration on traffic video supervisor,the work constitutes the non-linear mathematic model of image and inverse image,which based on affine principle and imaging principle,is introduced in this paper.It is decided the circle centre of image by external common tangent and acquired the non-linear equation model by optics imaging geometry.The model is solved by MATLAB,according to the error analysis,and the relatively error of model is less than 0.16%,which verifies the high precisio...
