Hierarchical encoder of stereo video space based on grid and decoding method thereof

The invention discloses a stereo video space scalable encoder based on grid and a coding method thereof, belonging to the technical field of image compression, mainly used for solving the blocking effect problem of prior scalable encoders based on block method. The encoder firstly performs Delaunay triangle subdivision to a left low resolution reconstructed image to obtain a triangle grid; then a current coding image is predicted by using a motion compensation and a parallax compensation based on the grid, and the left channel low resolution reconstructed image is used as a referent image; left channel prediction images and right channel prediction images with different resolution are obtained by the motion information and the parallax information of grid nodes; the original image respectively subtracts the prediction images to obtain corresponding residual images; then the residual images are respectively coded to form a composite bit stream. The stereo video space scalable encoder has the advantages that not only the scalable function can be realized, the blocking effect problem caused by the block method can also be reduced; the decoder and the method can be used to enable a decoding end to display single camera and binocular video with different resolutions according to different needs.
