Embodiment Construction

[0067] 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.

[0068] 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.

[0069] a. Motion tracking

[0070] 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.

[0071] b. Area Leaning

[0072] 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 a method and device for collecting indoor position data of a multilayer building, and a readable medium. The method comprises the following steps: obtaining a collection starting point marked by collection personnel in a starting collection layer of the to-be-collected multilayer building and geographical coordinates of the collection starting point; with the collection starting point as an original point of a Tango reference coordinate system, obtaining a deviation value of a geographical direction and a north direction identified by a 0-degree direction of the Tango reference coordinate system; and collecting three-dimensional coordinates of collection points in indoor floors of the multilayer building according to the obtained deviation value, the geographical coordinates of the collection starting point and an air pressure value collected by an air pressure sensor. By adoption of the technical scheme of the invention, the indoor position data of the multilayer building are collected based on the Tango technology, so that the collection error of the indoor position data can be reduced and the collection accuracy of the indoor position data is improved, accordingly the indoor positioning accuracy can be improved based on the collected indoor position data.

Description

【Technical field】 [0001] The invention relates to the field of computer application technology, in particular to a collection method, device and readable medium of indoor location data of a multi-storey building. 【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, that is, the geographic coordinates, and the WIFI fingerprint of each location point in advance, and then establishes the corresponding relationship between the coordinates of each location p...
