Problems solved by technology

[0004] However, in the existing WIFI indoor positioning, the location data of each location point, that is, the collection of geographic coordinates is mainly based on manual operations. If the geographical coordinates at both ends of the collection path manually obtained by the collection personnel are not accurate; or the collection personnel do not move at a uniform speed, or the collection personnel do not walk along the collection path, the geographic coordinates of each location point in the room will be the location. The data collection error is very large

Embodiment Construction

[0063] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0064] Tango is a new technology in an Augmented Reality (AR) project of Google (Google). Tango has the following three concepts, corresponding to three functional modules that can be set, and which functions can be selected to be enabled by setting the corresponding fields of the TangoConfig object.

[0065] a. Motion tracking

[0066] Mobile tracking means that Tango will record and track the position of the mobile device in 3D space. The position data includes the location and super image rotation angle, etc., and reports it to the application in real time.

[0067] b. Area Leaning

[0068] Mobile tracking only feeds back the current coordinate information of the mobile device, and has no memory of what the device "sees". Region learning enab...

Abstract

The invention provides an acquisition method and device of indoor position data, computer equipment and a readable medium. The method comprises the steps as follows: an acquisition starting point andinitial geographical coordinates of the acquisition starting point are obtained; acquisition is performed in an indoor road network of a building with the acquisition starting point as the origin of Tango, and a Tango track is obtained; the initial geographical coordinates of the acquisition starting point and the 0-degree direction of Tango are adjusted according to the initial geographical coordinates of the acquisition starting point, the initial geographical direction where the 0-degree direction of Tango is located, the Tango track and the road network of an indoor map of the building, sothat all acquisition points in the Tango track fall into the road network of the indoor map of the building, and the adjusted target geographical coordinates of the acquisition starting point and theadjusted target geographical direction corresponding to the 0-degree direction of Tango are obtained; position data of each indoor position point of the building are acquired according to adjustmentresults. The acquisition accuracy of indoor position data can be improved with the method.

Description

【Technical field】 [0001] The invention relates to the technical field of computer applications, in particular to a method and device for collecting indoor location data, computer equipment and a readable medium. 【Background technique】 [0002] As the indoor map coverage of map products increases, the demand for indoor positioning and navigation has also become very strong. The positioning of the most common Global Positioning System (Global Positioning System; GPS) in the prior art is mostly used in outdoor scenes. Due to the weak penetrating ability of the GPS, it cannot perform effective indoor positioning. Therefore, the existing indoor positioning mostly adopts WIFI positioning. [0003] The existing WIFI indoor positioning mainly collects the location data of each location point in the room in advance, that is, the geographic coordinates, and collects the WIFI fingerprints of each location point at the same time, and then establishes the corresponding relationship betw...
