Abstract: An information processing method includes: three-dimensional (3D) point information of a 3D point cloud is obtained; a two-dimensional (2D) point cloud image from projection of the 3D point cloud on a horizontal plane is generated based on the 3D point information; and projection coordinates of 3D points comprised in the 3D point cloud in a reference coordinate system of a reference plane graph are determined based on a consistency degree that the 2D point cloud image has with the reference plane graph, where the reference plane graph is used for representing a projection graph with reference coordinates that is obtained through the projection of a target object on the horizontal plane, and the 3D point cloud is used for representing 3D space information of the target object.

Abstract: The disclosure relates to a method, apparatus and system for anchor sharing, an electronic device and a storage medium. The method for anchor sharing includes: receiving, by a server, an anchor sharing request from a terminal, wherein the anchor sharing request comprises information associated with a present scene scanned by the terminal and an identifier of a to-be-shared anchor acquired by the terminal; determining, by the server, shared position information of the to-be-shared anchor in the present scene according to the anchor sharing request; and transmitting, by the server, the shared position information to the terminal.
