在图像跟踪系统中 ,图像目标的快速检测识别是至关重要的。基于目标的形状特性以及目标与背景的关系 ,提出了目标的四个特征量。结合序列图像中目标的运动特点 ,给出了一个目标快速识别的方案。以两类飞机为研究对象 ,对所求得的四种特征量值进行了详细的分析 ,并将所提出的识别方案在计算机上进行了模拟仿真。实验结果表明 ,该方法能有效地实现运动目标的快速检测识别 ,基本上达到了实时跟踪的要求 In the image tracking system, the rapid detection and recognition of the image target is crucial. Based on the shape characteristics of the target and the relationship between the target and the background, four characteristic quantities of the target are proposed. Combined with the motion characteristics of the target in the sequence image, a fast target identification scheme is given. Taking the two types of aircraft as the research object, the four characteristic values ​​obtained are analyzed in detail, and the proposed identification scheme is simulated on the computer. Experimental results show that the proposed method can effectively detect and recognize moving targets and basically meet the requirements of real-time tracking
