摘　　要：在仿真训练中,某型武器的电视跟踪系统的仿真采用了色键抠像技术来实现。色键抠像技术是电视节目制作领域产生节目画面的一种较为成熟的技巧,它通过高低电平的变换将两幅画面合二为一。通过分析装备的实际特点,使用色键抠像技术将电视跟踪系统的摄像机拍摄采集到的真实场景与计算机生成的虚拟空袭目标相融合,并最终在电视跟踪系统的监视器上显示,从而为反空袭一方的作战训练提供“看得见”的靶标,使训练更加贴近真实。In simulation training, the simulation of TV tracking system of a type of weapon system made use of chroma-key technology. Chroma-key is a kind of mature technique in the field of making TV pro- gram, it combined two pictures into one picture by use of pressure transfer between low and high. By means of character analysis of the weapon equipment, the real scene from TV tracking system and the virtual air attack target generated by computer were fused by means of chroma-key technology, and fused pictures were displayed on the monitor of TV tracking system so as to supply the ＂visible＂ target for operation training of the side of antl-air attack. This method has real training simulation capability and certain universality.
