Abstract
A three-dimensional scene constructing method, apparatus and system, and a storage medium. The three-dimensional scene constructing method includes: acquiring point cloud data of a key object and a background object in a target scene, wherein the point cloud data of the key object comprises three-dimensional information and corresponding feature information, and the point cloud data of the background object at least comprises three-dimensional information; establishing a feature database of the target scene, wherein the feature database at least comprises a key object feature library for recording three-dimensional information and feature information of the key object; performing registration and fusion on the point cloud data of the key object and the point cloud data of the background object, so as to obtain a three-dimensional model of the target scene; and when updating the three-dimensional model, reconstructing the three-dimensional model in a regional manner according to the feature database.
