Encoding and decoding method, code stream, encoder, decoder and storage medium

Abstract

The embodiment of the invention discloses an encoding and decoding method, a code stream, an encoder, a decoder and a storage medium, and the method comprises the steps: decoding the code stream at a decoding end, and determining azimuth sampling information corresponding to a current point cloud; and determining an initial predicted value corresponding to the current point cloud according to the azimuth angle sampling information corresponding to the current point cloud, and determining a predicted value of a point in the current point cloud according to the initial predicted value. At a coding end, azimuth sampling information corresponding to the current point cloud is determined, and the azimuth sampling information is written into a code stream; and determining an initial predicted value corresponding to the current point cloud according to the azimuth angle sampling information corresponding to the current point cloud, and determining a predicted value of a point in the current point cloud according to the initial predicted value.
