Abstract
It is very important to calculate fluid motion vector for natural landscape modeling of virtual reality interaction. This paper presents a new method of landscape fluid motion vector calculating. First, we use Plessy operator to extract feature points from two images and to calculate the match points using the area correlation matching method. Then the linear interpolation method with the shortest distance is used to interpolate the calculated motion vector to obtain dense fluid motion vector result. At last, we use the fluid continuity equation to optimize the dense fluid motion vector field to obtain dense and more accurate fluid motion vector calculation results. Further experimental results show that this method has the characteristic of simple and accurate. It is a valid method of fluid motion calculating and be used in the application of fluid simulation and virtual reality study.
