Abstract: In order to solve the problem of long interpolation time in traditional methods, intermediate interpolation method of VR glasses display animation based on hierarchical constraints is proposed. Firstly, the corresponding relationship between the 3D objects of VR glasses display animation is analysed. Secondly, the swing posture of the user's head is obtained, the virtual scene in the user's VR glasses display animation is adjusted and the image parameters of the in between of VR glasses display animation are obtained. Finally, the visual feature points are obtained by using the automatic feature point extraction method, and the intermediate interpolation is realised according to the interpolation algorithm based on hierarchical constraints. The experimental results show that when the number of iterations is 80, the image region overlap rate of this method is only 1.9% and when the number of animations is 100, the time of intermediate interpolation is only 112 ms.

Keywords: hierarchical constraints; VR glasses; display animation; intermediate interpolation; visual feature points.
