Abstract: A point cloud encoding and decoding method, an encoder, and a decoder are provided. The encoder determines a processing order of point cloud data during point cloud encoding. The encoder determines a coordinate-axis-order index corresponding to the processing order. The encoder encodes the coordinate-axis-order index and signals encoded bits into a bitstream. The encoder processes the point cloud data according to the processing order, to obtain point cloud data to-be-encoded. The encoder encodes the point cloud data to-be-encoded and signals encoded bits into the bitstream. The encoder determines the coordinate-axis-order index corresponding to the processing order as follows. The encoder sets a value of the coordinate-axis-order index corresponding to the processing order according to a correspondence table between preset indexes and processing orders.

Abstract: A point cloud model reconstruction method, an encoder, and a decoder are provided. The method includes the following. An i-th segmentation position of an i-th three-dimensional slice on a longest edge in a point cloud space is obtained, where 1≤i≤n−1 and n is a total number of three-dimensional slices to-be-processed. An i-th cube block set nearest to the i-th segmentation position in the i-th three-dimensional slice is determined based on the i-th segmentation position and a preset cube block length. An i-th vertex position with a cube block in the i-th cube block set is determined along the longest edge, where the i-th vertex position represents a position of a vertex on an edge which is away from a start position of the cube block by the preset cube block length. A point cloud model is reconstructed based on the i-th vertex position.

Abstract: Implementations of this application provide point cloud partition methods, an encoder, and a decoder. The method includes the following. Morton codes for a point cloud are obtained according to geometry information of the point cloud. The point cloud is determined as an input point cloud of an iteration. Morton codes for an input point cloud of an i-th iteration are right shifted by K bits according to a number of points in the input point cloud of the i-th iteration, where K is a positive integer. A point is selected from points with a same value of Morton codes after right shifted by K bits. An i-th level of detail (LOD) layer is formed with the point selected.

Abstract: A front cover assembly includes a frame, a cover glass, and a waterproof glue. The frame has a receiving cavity. The cover glass is partially received in the frame. The cover glass has a lateral face facing the frame. The cover glass has a step portion located at the lateral face. A first gap is defined between a first face of the step portion of the cover glass and a first wall of the frame, and a second gap is defined between a second face of the step portion of the cover glass and a second wall of the frame. A waterproof glue fills the first and second gaps. The first and second faces of the step portion from an obtuse angle therebetween, which faces the first and second walls of the frame. The present disclosure also relates to a terminal.
