摘要: 为了监测出核爆炸,采用一种改进的Horn-Schunck算法,进行了理论分析和实验验证.计算出连续帧核爆图片的光流场,绘制出光流场图.例如,取第1159帧和第1160帧图像,得到了水平光流均值为0.018181pixel/s,均方差为0.375775pixel/s;垂直光流均值为-0.503308pixel/s,均方差为0.896142pixel/s.结果表明,根据图形及速度分布能够判断出核爆炸.

Abstract: A improved Horn-Schunck algorithm method was proposed to judge nuclear explosion.The optic flow field of a consecutive sequence of frames of nuclear explosion was calculated and the picture of optic flow field was drawn.For example,the average horizontal optical flow field was 0.018181pixel/s with a mean square deviation(MSD)of 0.375775pixel/s and the average vertical optical flow field was -0.503308pixel/s with a MSD of 0.896142pixel/s at the 1159th frame and the 1160th frame.A preliminary judgment can be made that it is a nuclear explosion according the picture and velocities distribution.
