非制冷热像观瞄系统动态目标的智能检测

Auto-detection of moving object for un-cooled thermal sight system

为了适应实时性的要求,在目标检测及定位时对处理方法的简洁性提出了很高的要求。基于热像观瞄系统,根据观瞄的目的,介绍了一种具有一定大小的目标检测方法。根据差分图像像素特性,提出了自适应选取阈值的新方法,对目标像素的亮度和分布密度进行精确定位。这种方法充分考虑了像素的自身属性信息,便于硬件的实时处理。该方法可以达到较高的检测率。

In order to shorten the processing time, the simplicity of processing method is required. The method of detection for certain size moving object is introduced on the basis of thermal sight system. The new method for adaptive threshold is improved on the ground of trait of difference image pixels, and the brightness and distributing density of object pixels are used to look for the specific position. This method depends on the attribute of object pixels completely, and is realized in hardware system. The higher detection rate can be acquired with this method by experiment.
