摘　　要：研制了一种六自由度跟踪设备,通过采集红外图像,提取出预先安放在环境中多个(n>6)红外标志点的二维坐标,推导了根据二维红外图像中标志点距离值获取摄像机六自由度位置的线性算法,试验结果证明了系统的有效性。An infrared-based tracking system is developed, which is composed of multiple （n〉6） infrared LED markers, personal computer, and a PC-camera. The infrared LED markers are placed in the real world beforehand. A CMOS PC-camera, which is attached with a slice of infrared-filter glass, is used to capture infrared images. After image procession, captured infrared images can be filtrated as some sign-points to indicate the 2D position of those LED markers. By means of linear pose estimation algorithms, the 6 DOF relative pose of the infrared camera in the real world coordinates can be estimated from limited LED markers in real time.
