Automatic Detection of the Moving Point Target in the Multi-channel Composite Optical Imaging System

单纯对单孔径光学成像系统的图像数据进行检测处理 ,来实现对运动点目标的自动检测和判别是非常困难的 本文根据多通道复合式光学成像系统多个通道视场有重叠的固有特点 ,建立了应用于该系统的运动点目标自动检测和判别方法 实际系统上测试证明了所设计检测方法有效地提高了运动点目标检测的概率 ,减少了误判和虚警 。

It is quite difficult to the automatic detection and recognition of the moving point target by the detecting processing of the images grabbed from the mono aperture imaging system. According to the inner feature of the view field overlapping in the multi channel compound optical imaging system, the automatic detection and recognition approach of the moving point target for this system is built up. The applied result in the practical system showed that the designed detection and recognition approach increased the detecting probability of the moving point target, and decreased the probability of false alarms. The detecting method was proved to be feasible and effective.
