Embodiment Construction

[0036] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as recited in the appended claims.

[0037] figure 1 It is a flow chart of a positioning method shown according to an exemplary embodiment. The method can run on a mobile terminal, or on a server that performs data transmission with the mobile terminal, such as figure 1 As shown, the positioning method may include the following steps.

[0038] In step S110, the positioning photos collected in the mobile terminal on the scene positions in the preset scene are acquired.

[0039] The positioning photo is a photo collected at a scene position of a preset scene. For example, when the user is at the scene p...

Abstract

The invention discloses a positioning method and device and a mobile terminal and belongs to the field of computer application technology. The method comprises the steps that a positioning picture collected for a scene position in a preset scene in the mobile terminal is acquired; measurement learning is performed on the positioning picture and image features in feature indexes; the similarity between the positioning picture and each image feature is calculated; the feature indexes are association indexes between the image features extracted from a panoramic video collected from the preset scene and corresponding scene positions in the preset scene; a target image feature most similar to the positioning picture is determined according to the similarities; and the scene position associatedwith the target image feature is determined from the scene positions of the feature indexes, and a panoramic image frame corresponding to the scene position is positioned in the panoramic video. Through the positioning method and device and the mobile terminal, high-precision positioning can be performed on the scene position conveniently.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a positioning method and device, and a mobile terminal. Background technique [0002] Due to the maturity of GPS technology and the universality of coverage, outdoor navigation is very common and frequently used. However, in indoor places, due to the accuracy limitation of GPS technology and poor signal penetration, such as indoor places such as large shopping malls and public places, it is difficult for users to locate accurately, and it is often difficult to find target stores, commodities, facilities, etc. Difficulties, resulting in high time costs and low efficiency. [0003] At present, when positioning indoors, Bluetooth iBeacon, Wifi, etc. are mainly used for positioning. When positioning through Bluetooth iBeacon, it is necessary to build a gateway route to connect the signals in series. The user connects to the nearest iBeacon device through Bluetooth to ...
