Embodiment Construction

[0030] Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited by the exemplary embodiments described here.

[0031] Application overview

[0032] As mentioned above, aiming at the problem of positioning accuracy in indoor positioning scenarios, the basic concept of the present application is to further calibrate the positioning results obtained by various positioning methods through building structure data, so as to improve the positioning accuracy.

[0033] This is because when the object to be positioned is located in a building, its positioning result cannot deviate into an area inaccessible to the building, for example, it cannot be located outside the range o...

Abstract

The present invention relates to a building structure data-based object method, a building structure data-based object positioning device and an electronic device. The method includes the following steps that: the first position of an object to be positioned is obtained by using a first positioning method; the second position of the object to be positioned is obtained by using a second positioningmethod; the moving direction of the object to be positioned is obtained based on the first position and the second position; and the second position and the moving direction are corrected based on building structure data, so that the positioning result of the object to be positioned can be obtained. In this way, the positioning result can be calibrated through the building structure data, and theaccurate positioning of an interior structure can be achieved.

Description

technical field [0001] The present application generally relates to the technical field of positioning, and more specifically, relates to an object positioning method, device and electronic equipment based on building structure data. Background technique [0002] With the development of positioning technology, more and more ways of positioning through wireless signals have emerged. For example, in the field of indoor positioning, common positioning methods include WIFI positioning, Bluetooth positioning, infrared positioning, RFID positioning, ultrasonic positioning, ZigBee positioning and ultra-wideband (UWB) positioning. [0003] These wireless positioning technologies mainly measure the target node through the distance or angle from the target node to the receiving node, and then calculate the position information. Wireless ranging technology can be divided into ranging technology based on received signal strength (RSSI), ranging technology based on signal angle of arriv...
