Abstract: This application provides a rotation mechanism and a foldable terminal. The rotation mechanism includes a fixed base, a first swing arm, a second swing arm, a first limiting member, and a second limiting member. A first sliding groove and a second sliding groove are disposed on the fixed base. A first rotation shaft part of the first swing arm is installed in the first sliding groove, and may rotate relative to the fixed base. A second rotation shaft part of the second swing arm is installed in the second sliding groove, and may rotate relative to the fixed base. Rotation directions of the first rotation shaft part and the second rotation shaft part are opposite relative to the fixed base. The first limiting member is disposed in a first sliding hole of the first rotation shaft part, and is fixedly connected to the fixed base. When the first rotation shaft part rotates relative to the fixed base, the first limiting member slides relative to the first rotation shaft part along the first sliding hole. The second limiting member is disposed in a second sliding hole of the second rotation shaft part, and is fixed to the fixed base. When the second rotation shaft part rotates relative to the fixed base, the second limiting member slides along the second sliding hole relative to the second rotation shaft part.

Abstract: The present invention discloses a point cloud sequence encoding/decoding method and apparatus based on two-dimensional regularized plane projection. The encoding method includes: acquiring reference-frame point cloud data and current-frame point cloud data; performing two-dimensional regularized plane projection on the reference-frame point cloud data to obtain a first two-dimensional projection plane structure, and performing two-dimensional regularized plane projection on the current-frame point cloud data to obtain a second two-dimensional projection plane structure; performing motion compensation and encoding on one or more pieces of first two-dimensional graphic information obtained based on the first two-dimensional projection plane structure and one or more pieces of second two-dimensional graphic information obtained based on the second two-dimensional projection plane structure to obtain bit stream information of the current-frame point cloud data; and repeating the foregoing steps until all frames of a point cloud sequence are encoded. The present invention can fully utilize spatia-temporal correlation of a point cloud sequence for encoding the point cloud sequence, which reduces temporal and spatial redundancy of the point cloud sequence and improves encoding efficiency.

Abstract: Disclosed are a point cloud encoding and decoding method and device based on a two-dimensional regularization plane projection. The encoding method includes: acquiring original point cloud data; performing two-dimensional regularization plane projection on the original point cloud data to obtain a two-dimensional projection plane structure; obtaining a plurality of pieces of two-dimensional image information according to the two-dimensional projection plane structure; and encoding the plurality of pieces of two-dimensional image information to obtain code stream information. According to the present invention, a point cloud in a three-dimensional space is projected to a corresponding two-dimensional regularization projection plane structure, and regularization correction is performed on the point cloud in a vertical direction and a horizontal direction, to obtain a strong correlation representation of the point cloud on the two-dimensional projection plane structure, so that the spatial correlation of the point cloud is better reflected; and when the plurality of pieces of two-dimensional image information are subsequently encoded, the spatial correlation of the point cloud can be greatly utilized, and the spatial redundancy is reduced, thereby further improving the encoding efficiency of the point cloud.
