摘要
为了快速准确地从背景中检测出移动目标,并控制云台对目标进行自动跟踪,提出了一种移动目标的自动监视报警方法。该方法充分利用连续图像特性,采用改进的帧间减影法检测运动,并用差分图像的阈值化方法分割出动目标;进而采用光谱滤波等技术提高图像传感器的探测灵敏度,进一步提高了该方法的作用距离。仿真结果表明,该方法可以有效、准确地对移动目标进行检测和跟踪。
In order to detect moving object from background, and control console to track target automatically, an automatic surveillance and warning method for moving object is developed. According to the characteristic of the serial images, the motion is detected and the objects is segmented from background. Through the spectrum filer technology, the detecting sensitivity of CCD （charge coupled device） sensors is improved. The simulation results indicate that this method can detect and track moving object effectively and accurately. 3 figs, 5 refs.
