运动目标的检测技术研究

Study of detection technique of target moving

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 。

Target detection and recognition is one of the most important steps in an image tracking system. An efficient method for target detection and recognit ion is presented, which is based on target feature extraction and target moving direction. The result of computer simulation shows that the method is pra ctical and has high speed in detection and recognition for moving target.
