摘要 光学式虚拟演播室系统的关键技术之一,是在较强噪声环境下,可随时方便的快速进行摄像机校准,这也是它 区别于传统的基于机械传感器的虚拟演播室系统的特性之一.在这篇文章中,我们分析了光学跟踪的虚拟演播室系统 对摄像机校准算法的特殊要求,给出了一个实用的摄像机校准算法,并且对算法的结果进行了具体分析. One of the key issues of virtual set is the camera calibration. We propose a flexible technique to calibrate the camera. This technique do not requires expensive equipment such as two or three orthogonal planes. Simulated and real data have been used to test the proposed technique, and very good results have been obtained.
