Abstract

The present invention relates to the field of indoor positioning and particularly relates to a high precision indoor positioning system and corresponding method based on a characteristic light source and a spherical lighting device. The positioning is three-dimensional spatial positioning. The system comprises the characteristic light source, the spherical lighting device and a processor. The method comprises the steps of light source arrangement, information inputting, position selection and lighting, characteristic matching, 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, good real-time performance, and excellent scalability and portability.

Description

technical field [0001] The invention relates to the field of indoor positioning, in particular to a high-precision indoor positioning system based on a characteristic light source and a spherical lighting device 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 gr...
