Embodiment Construction

[0031] 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.

[0032] Application overview

[0033] As mentioned above, in the field of precise positioning, for example, the precision of precise positioning using ultra-wideband (UWB) technology can reach centimeter level. The base station determines the position of the object to be positioned by receiving a signal of the object to be positioned (for example, a location identification card worn by a person).

[0034] However, this kind of precise positioning has limitations in detecting overlapping objects. For example, in the case of one person carrying two positionin...

Abstract

The application relates to a method and apparatus for detecting overlapping objects based on positioning data and an electronic device. The method comprises the following steps: acquiring first positioning data of a first object and second positioning data of a second object within a plurality of time periods; on the basis of the first positioning data and the second positioning data and setting an overlapping identifier for indicating whether a distance between the first object and the second object is less than a predetermined distance threshold within each time period; carrying out countingon the number of overlapping identifiers within the plurality of time periods to obtain an overlapping number of times; dividing the overlapping number of times by the number of the plurality of timeperiods to obtain an overlapping rate; and determining the first object and the second object are overlapping objects in response to the overlapping rate being greater than a predetermined percentagethreshold. Therefore, the overlapping rate indicator for detecting the overlapping object is calculated by positioning data, so that the detection accuracy of the overlapping object is improved.

Description

technical field [0001] The present application generally relates to the field of detection technology, and more specifically, relates to a method, device and electronic device for detecting overlapping objects based on positioning data. Background technique [0002] Precise positioning has become the focus of attention in recent years due to the growing business demand for precise positioning. [0003] The main methods for obtaining wireless positioning data are TOA (Time of Arrival, positioning technology based on signal arrival time), TDOA (Time Difference of Arrival, positioning technology based on signal transmission time difference of arrival), AOA (Angle of Arrival, based on signal angle of arrival positioning technology), etc. They need to measure the distance, time difference or angle from the base station to the moving node first, and then further calculate the position information. [0004] However, after obtaining the position data of multiple positioning object...
