概念设计平台中的摄像机标定方法

提出了一个基于增强现实技术的概念设计平台原型系统,应用双目立体视觉的方法,实现对油泥模型和雕塑刀具的跟踪.本文基于平面标志物进行标定的方法,对原型系统中的CCD进行了标定,获得了正确的摄像机参数.实验结果表明,该系统中使用的镜头存在严重的非线形畸变,通过对镜头进行校正的方法,获得了无畸变的理想图像.

Camera Calibration Method of Conceptual Design Platform

A prototype system on Augmented Reality -based Conceptual Design Platform is proposed in this paper. Based on the binocular stereo vision methods,the stereo localization system implements the tracing of sculpture tools and the mock-up. In this paper, a new calibration method is applied which uses a planar pattern, and the accurate camera's parameters are obtained through the CCD calibrating of the prototype system. The experiment result shows that there is severe non-linear distortion in the lens, and the perfect image is obtained in this paper by correcting lens distortion.
