Embodiment Construction

[0034] In order to describe in more detail the indoor positioning system and positioning method for multiple characteristic light sources of the present invention, the present invention will be described in detail below with reference to the accompanying drawings by taking a specific scene as an example. In this embodiment, there are two characteristic light sources to be positioned, which are marked as characteristic light source A and characteristic light source B, which have the same frequency and different codes.

[0035] Such as figure 1 As shown, the indoor positioning system for multiple characteristic light sources of the present invention includes a lighting device, a communication module and a processor, wherein:

[0036] The lighting device is used to collect the light emitted by each characteristic light source in the room, record its frequency, code and incident angle, and transmit it to the communication module;

[0037] The communication module is used to rece...

Abstract

The present invention relates to the field of indoor positioning and particularly relates to an indoor positioning system and positioning method for multiple characteristic light sources. The positioning is three-dimensional spatial positioning. The system of the invention comprises a light collection device, a communication module, and a processor. The method of the invention comprises the steps of device arrangement, information recording, signal collection, and position calculation. Compared with a traditional indoor positioning system, the indoor positioning technology provided by the invention has the advantages of high accuracy, low cost, and good real-time performance.

Description

technical field [0001] The invention relates to the field of indoor positioning, in particular to a high-precision indoor positioning system for multiple characteristic light sources and a corresponding method. Background technique [0002] In recent years, with the advancement of science and technology, positioning technology has also attracted much attention and developed rapidly. Today, GPS-based outdoor positioning technology has been very mature and has begun to be widely used, but as the end of positioning technology, the development of indoor positioning technology has been relatively slow. Existing indoor positioning technology senses the position and movement of indoor objects through infrared, ultrasonic and other means, or performs data interaction with the object to be measured through wireless communication means such as Wi-Fi, Bluetooth or ZigBee. The technical means adopted by the former can achieve higher accuracy, but it also greatly increases the complexit...
