Embodiment Construction

[0032] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0033] The "plurality" mentioned herein means two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. The character " / " generally indicates that the contextual objects are an "or" relationship.

[0034] In related technologies, when indoor positioning is implemented based on WiFi fingerprints, a large number of WiFi devices need to be deployed indoors in advance, and the room is divided into several grids. WiFi fingerprint. When performing indoor positioning, the terminal determines the real-time WiFi fingerprint of the current loca...

Abstract

The embodiment of the invention discloses an indoor positioning method and device, a terminal and a storage medium, and belongs to the field of terminal positioning. The method comprises the steps ofobtaining a target image; performing character recognition on the characters in the target image, and determining a target place where the target image is photographed according to a character recognition result; performing image recognition on the target image, and determining a target position in the target place according to an image recognition result, the target position being a position where the target image is photographed, and the target position belonging to a preset photographing position in the target place; and displaying the target position in an indoor map corresponding to the target place. According to the embodiment of the invention, indoor positioning is realized based on the character and image recognition technology, and WiFi equipment or a visible light source does notneed to be preset indoors, so that the realization difficulty and cost of indoor positioning are reduced.

Description

technical field [0001] The embodiments of the present application relate to the field of terminal positioning, and in particular to an indoor positioning method, device, terminal and storage medium. Background technique [0002] Indoor positioning is a technology for positioning in an indoor environment. [0003] Compared with the outdoor environment, since there are a large number of occluders in the indoor environment, the accuracy of positioning by using a positioning component (such as a Global Positioning System (Global Positioning System, GPS)) indoors is poor. In order to improve the accuracy of indoor positioning, in related technologies, a terminal usually implements indoor positioning based on a wireless-fidelity (Wireless-Fidelity, WiFi) fingerprint or visible light technology. When indoor positioning is realized based on WiFi fingerprint or visible light technology, a large number of WiFi devices or visible light sources for positioning need to be pre-installed ...
