一种改进的光流法及其在云爆弹研究中的应用

An Improved Optical Flow Method and Its Application in Study on FAE

提出了抑制光线影响的改进光流法,并将其运用在云爆弹爆炸云雾扩散速度探测估计研究中。首先使用高斯核平滑滤波器,对所获得云爆弹爆炸图像序列进行预处理;然后利用rgb彩色模型在白光照射下的不变性,将RGB模型转换为rgb模型;最后使用基于rgb模型的光流法,得到爆炸过程中的云雾扩散速度。实验证明该方法能获得满意的处理效果。

An improved optical flow method,which can eliminate the disturbance of the changing illumination,isproposed and applied in the research on FAE.Firstly,images are preprocessed by Gaussian kernel smooth filter;secondly,due to the invariability of rgb color model, RGB model is convert to rgb model;finally, the improvedoptical flow method based on rgb model is applied in the estimation of the velocity of the diffusing cloud in explo-sion. It has been proved by the experiments that this method can get a satisfied result.
