Embodiment 1

[0023] figure 1 A flow chart of an indoor positioning method provided by the first embodiment of the present invention is shown, and the details are as follows:

[0024] Step S11, the camera receives the scanning instruction sent by the monitoring system, and according to the scanning instruction, turns on the preset Bluetooth scanning for nearby Bluetooth devices;

[0025] In this step, in order to realize scanning via Bluetooth, it is first necessary to add a Bluetooth chip to the camera hardware. After receiving the scanning command sent by the monitoring system, multiple cameras simultaneously turn on the preset Bluetooth chip, and the surrounding smartphones with the Bluetooth function terminal to scan. Most of the smart terminals currently on the market already support Bluetooth 4.0 (or higher). When the user turns on the Bluetooth function switch on the smart terminal, the camera can search for the smart terminal with the Bluetooth function enabled through the Bluetoot...

Embodiment 2

[0047] image 3 A schematic diagram of a positioning system provided by the second embodiment of the present invention is shown. The positioning system can be applied to various terminals. For convenience of description, only parts related to the embodiment of the present invention are shown.

[0048] like image 3 As shown in the figure, after multiple cameras receive the scan command sent by the monitoring system at the same time, they start the preset Bluetooth and scan the surrounding Bluetooth devices; in this way, the same Bluetooth device can be scanned by the Bluetooth chips in multiple cameras at the same time, and then the cameras Receive the returned parameters of the scan, process the returned parameters, and send them to the monitoring system. The monitoring system calculates the relative position of the Bluetooth device and multiple cameras based on the received scanning information, and then determines the specific position of the Bluetooth device according to t...

Abstract

The invention is suitable for the field of video monitoring positioning and provides an indoor positioning method and system. The method comprises the following steps that a camera receives a scanning instruction sent by a monitoring system and opens preset Bluetooth for scanning a Bluetooth device around according to the scanning instruction; the camera reads a return parameter of a scanning result and uploads the return parameter to the monitoring system; and the monitoring system determines the location of the Bluetooth device. By setting the Bluetooth chip on the camera in advance, the camera is used for shooting the user and the Bluetooth chip is used for positioning when the method is used for achieving passive monitoring of the Bluetooth device, the tedious process that the manual positioning is carried out by the staff after shooting with the camera is avoided, and the positioning efficiency is improved.

Description

technical field [0001] The embodiments of the present invention belong to the field of video monitoring and positioning, and in particular relate to an indoor positioning method and system. Background technique [0002] With the continuous development of Bluetooth applications, most of the smart mobile terminals currently support Bluetooth 4.0 and above standards. The Bluetooth 4.0 standard includes two Bluetooth standards. To be precise, it is a dual-mode standard. Call it Classic Bluetooth (Classic Bluetooth) and Bluetooth Low Energy (Bluetooth Low Energy). Traditional Bluetooth is developed and perfected on the basis of previous 1.0.1.2, 2.0+EDR, 2.1+EDR, 3.0+EDR, etc. Bluetooth low power consumption is developed on the basis of Nokia's Wibree standard, using Bluetooth technology for positioning method has become increasingly common. [0003] Positioning technology can be divided into active positioning and passive positioning. Active positioning means that the client a...
