Abstract
Embodiments of this application provide methods and apparatuses for compressing and decompressing a three-dimensional (3D) map, to reduce a data volume of a 3D map. The method for compressing a 3D map includes: obtaining a 3D map descriptor, where the 3D map descriptor corresponds to at least one 3D map point of the 3D map; performing binarization on a relationship between the 3D map descriptor and at least one preset threshold vector to obtain binary data; and performing quantization on a difference between the 3D map descriptor and the at least one preset threshold vector to obtain quantized data.
