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...
