Abstract
Nearest neighbour search methods, an encoder, and a decoder are provided. In the method, position information of point cloud data to be searched is acquired; slicing is performed on the point cloud data according to the position information and a distance threshold to obtain current-layer data; a corresponding parent node is obtained according to the current-layer data in the point cloud data and a preset number of bits by which position information bits of prediction data corresponding to the current-layer data in the point cloud data are shifted right; a neighbour area in the first-parent node is determined, a nearest neighbour point of the current-layer data in the neighbour area is determined, and searching is performed in a preset search range corresponding to the search point to determine the nearest neighbour point.
