Embodiment Construction

[0035] 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.

[0036] Application overview

[0037] As mentioned above, in some scenarios, for example, in a coal mine underground positioning scenario, for example, to ask for help or avoid underground, it is desired to be able to determine other positioning objects around the positioning object.

[0038] In addition, when the underground vehicle is driving, it is necessary to determine in real time whether there are other vehicles driving around the vehicle, so as to inform the driver in advance whether to take evasive measures and how to avoid other vehicles.

Abstract

The invention relates to a method and a device for determining a positioning object in a predetermined area and an electronic device. The method comprises the steps of obtaining coordinates of a reference positioning object; converting the coordinates of the reference positioning object into reference codes based on a space filling curve; determining a reference area in which the reference positioning object is located based on the reference code, wherein the reference area is one of a plurality of subdivided areas obtained by encoding the predetermined area based on the space filling curve; determining at least one reference area within a predetermined distance from the reference area, wherein the at least one reference area belongs to the plurality of subdivided areas; and determining areference positioning object within the at least one reference region based on the spatial fill curve encoding of the at least one reference region. In this way, the calculation cost is remarkably saved, and the operation efficiency is improved.

Description

technical field [0001] The present application generally relates to the technical field of positioning, and more specifically, relates to a method, device and electronic equipment for determining a positioning object in a predetermined area. 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 ...
