摘　　要：根据实际设计了一种军用数字电视跟踪器 ,对其中的关键技术———任意指定图像目标的检测和跟踪作了介绍 ,讨论了其数学模型 ,针对不同的实际场景提出了不同的算法 ,即基于灰度域图像分割的跟踪算法和基于特征图像匹配的跟踪算法 ,并结合实际设计讨论了硬件实现的关键技术 ,最后给出了实际的跟踪效果。实际实验结果表明 ,该模型和跟踪算法可以有效地跟踪实际战场环境下的各种目标。According to a television tracking system for army, this paper introduces a key technology——detecting and tracking arbitrary specific image target in real time, discusses its mathematical model and presents different algorithms to the real different situation. One is based on the image segmentation in gray, and another is based on the image matching. At last, this paper analyzes the key technologies in hardware design, and gives the results of tracking targets in real situation. The real results show that this model and algorithms are efficient in tracking various targets in battlefield situation.\;
