Abstract: The embodiment of the present disclosure provides a positioning method, a positioning device and system, an electronic equipment and a computer readable medium. The positioning method comprises: establishing connection with a target node in response to feedback information returned by the target node; acquiring initial position information; acquiring real-time position information for multiple times; and positioning the target node according to the acquired initial position information and the real-time position information acquired for multiple times. wherein the real-time position information comprises the direction and the distance of the movement of the source node relative to the last position of the source node, the direction and the distance of the movement of the target node returned by the target node relative to the last position of the target node, and the distance between the target node and the source node.

Abstract: A data transmission method, includes: receiving N data packets sent by a communication opposite-end device, wherein each data packet includes a piece of target data, and N is a positive integer greater than 1; according to a receiving sequence of the N data packets from a first data packet to an Nth data packet, sequentially determining whether a transmission error occurs in each data packet; if it is determined that a data packet is transmitted incorrectly, storing, in a first queue, a piece of first indication information which indicates the data packet is transmitted incorrectly; and after it is determined that the reception of the N data packets ends, generating a first retransmission instruction, and sending the first retransmission instruction to the communication opposite-end device, wherein the first retransmission instruction includes information in the first queue.

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.
