AI Technical Summary

Technical Problem

Existing technologies suffer from low accuracy, high cost, and insufficient universality in mobile device positioning scenarios. In particular, the accuracy of self-built maps is insufficient and the hardware deployment cost is high, making it impossible to effectively reuse high-precision map resources.

Method used

A map of the target location is constructed using a second device, and the first device reuses this map for positioning. Global and local feature matching is performed in conjunction with environmental image information to achieve low-cost, high-precision positioning.

Benefits of technology

It achieves low-cost, high-precision, and reusable positioning results, and is suitable for various scenarios, including accurate positioning and navigation in complex environments such as underground parking lots.

Abstract

The present disclosure provides a positioning method, a positioning device, a positioning system, an electronic device and a storage medium. The method comprises: obtaining a target site map of a target site where a first device is located, the target site map being constructed by a second device that has a pre-established association relationship with the first device; collecting environmental image information of a current position of the first device in the target site; and determining the position of the first device in the target site based on the target site map and the environmental image information. The target site map constructed by the second device is reused when the first device is positioned in the target site, thereby ensuring low-cost, high-precision and reusable positioning effect.
