无人值守变电站运动检测算法研究

提出了一种基于比率图像的运动检测算法。针对目前研究普遍使用的差分图像的不足,结合光学知识,得到了比率图像的累计直方图,并根据累计直方图和运动对象在图像中的特点提出了一种可行的阈值分割方法,并与传统Ostu方法的二值化结果比较。最后对该阈值分割方法进行评价。实验及应用结果表明,该算法对于运动物体侵入的异常检测率比较高。

Study on Algorithm of Motion Detection in Unattended Substation

An exercise detection algorithm based on the ratio images was proposed. Aiming at the defects of the difference image, and optical knowledge was combined with, the ratio of the cumulative image histogram was Obtained, According to the features of the cumulative histogram and sports objects in the images, a feasible method of threshold segmentation was provided, and with which the traditional methods of Ostu binarization results are compared. Finally the threshold segmentation method were evaluated. Experime...
