摘要
本文详述了摄像机成像原理及其坐标变换关系,分析了针孔摄像机成像模型,并在此基础上建立了包括径向畸变、切向畸变和薄棱镜畸变的摄像机模型.对摄像机进行了标定,利用标定结果对空中物体进行了三维坐标计算.试验的精度表明,实验布置方法和标定方法能够满足工程测量的需求,具有一定的应用价值。
In this paper, the imaging principle and coodinate transformation of a video camera are described in detail. The imaging model of a pinhole video camera is analyzed. On the basis of the above analysis, a video camera model including radial distortion, tangential distortion and thin prism distortion is established. A video camera is calibrated and the calibration result is used to calculate the 3-D coordinates of an object in air. The experimental result shows that the experimental arrangement and calibration method can satisfy the need of the project measurement and are of a certain application value.
