Estimating Velocity of Moving Objects Using an Improved Optical Flow Method

摘要

In order to eliminate the disturbance of the changing illumination during the process of estimating the velocity of moving objects, an improved optical flow method is proposed and applied in the research on FAE in this paper. First of all, images are preprocessed by Gaussian kernel adaptive smooth filter; Secondly, according to the illumination invariability of rgb color model, we convert RGB color model to rgb color model; Finally, the improved optical flow method based on rgb color model is applied in the estimation of the velocity of the diffusing cloud in FAE explosion. It has been proved by the experiments that we can get a satisfied result by using this method.
