增强现实系统中的摄像机校准算法研究

摘要

One of the key issues of AR is the camera calibration. We proposea flexible technique to calibrate the camera. This technique only requires the camera to observe a planar pattern. Real data have been used to test the proposed technique, and very good results have been obtained. Compared with classical techniques which use expensive equipment such as two or three orthogonal planes,the proposed technique is easy to use and flexible.%增强现实系统的关键技术之一是精确定位问题，当用户改变他/她的观察视点时，虚拟对象必须与真实对象的运动方向与位置保持一致，这样才能使用户感觉到虚拟对象融入到真实环境中.而要做到这一点，就必须研究摄像机校准问题.在这篇文章中，我们分析了增强现实系统对摄像机校准算法的要求，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.
