摘　　要：现有光电跟踪系统,由于工艺等原因很难将变焦距摄像机在连续变焦的同时保持光轴线的一致性,造成较大的系统误差而无法满足高精度跟踪要求。为解决电视摄像机在连续变焦过程产生光轴线的偏移问题,提出了一种动态软件补偿技术。该技术运用最小二乘法修正摄像机在变焦的动态过程中的光轴偏移量。实验结果表明:该方法具有易于实现和应用、通用性强、准确度高等优点。The existing photo-electronic tracking system is very difficult to keep the optical axis＇s uniformity of the zoom camera at the same time of continual focal variation due to the limit of the process, etc. The big system error can＇t satisfy the high accuracy track request. To solve the optic axis offset of the TV camera, this article proposed a dynamic software compensation technology in continual focal variation process. This technology modifies the optic axis offset of the camera in focal variation dynamic process by the least square method. The experimental result indicated that this method will solve this problem easily. It also has the advantage of the better versatility and the higher accuracy.
