AI Technical Summary

Problems solved by technology

[0004] However, base station positioning has high requirements on equipment, and once there is a problem with the equipment, it will affect the positioning accuracy
The deployment cost of Bluetooth positioning is relatively low, but the positioning accuracy will change with the signal fluctuation of the Bluetooth device. Once the power of the Bluetooth device is insufficient, the signal strength will decrease, resulting in a decrease in positioning accuracy, and large-scale deployment is required
Traditional AR positioning is performed by scanning QR codes, and the recognition speed is slow

Abstract

The embodiment of the invention discloses an indoor positioning method and device based on vision, equipment and a storage medium. The method comprises the steps of obtaining first actual position information in an actual scene, first augmented reality position information in the augmented reality scene, a first conversion relationship and a second conversion relationship when an augmented realitymark code is detected; acquiring second augmented reality position information in the augmented reality scene in the process of not detecting the augmented reality mark code; and determining second actual position information in the actual scene according to the first actual position information, the first augmented reality position information, the second augmented reality position information,the first conversion relationship and the second conversion relationship. By operating the technical scheme provided by the embodiment of the invention, the problems of high deployment cost, unstablepositioning precision and low positioning speed can be solved, and the effects of reducing the deployment cost, improving the positioning precision stability and improving the positioning speed are achieved.

Description

technical field [0001] Embodiments of the present invention relate to positioning technology, and in particular, to a vision-based indoor positioning method, device, equipment, and storage medium. Background technique [0002] With the rapid development of science and technology, positioning technology is widely used in various fields. Among them, outdoor positioning technology has basically met the needs of people's lives, but indoor positioning still has problems such as inaccurate accuracy. [0003] At this stage, the problems in indoor positioning are usually solved by base station positioning, Bluetooth positioning and traditional augmented reality (Augmented Reality, AR) positioning: [0004] However, base station positioning has high requirements on equipment, and once there is a problem with the equipment, it will affect the positioning accuracy. The deployment cost of Bluetooth positioning is relatively low, but the positioning accuracy will change with the signal ...
