In order to restore video information accurately,aimed at the problems of low inter frame fidelity and compression of cross media video,a cross media video key frame restoration method supported by mobile AR+VR is designed.The feature points of cross media video key frames are extracted by the SIFT method,and the key frames are extracted repeatedly to form a key frame set.The AR+VR technology is used to establish the panorama AR prediction model according to the attributes and features,correct the panorama,establish the matching matrix,match the VR video inter frame sequence,and realize the restoration of cross media video key frames supported by mobile AR+VR.Experimental results show that this method has high accuracy,fidelity and compression ratio,and has good key frame restoration effect.
