Abstract

The invention discloses a three-dimensional space detection system, a positioning method and a system, the positioning system comprises a positioning base station, a to-be-positioned marking device and a calculating device, the positioning base station synchronizes a standard time with the to-be-positioned marking device, transmits a supersonic wave signal, rotatably transmits a first laser plane signal around a first rotating shaft and rotatably transmits a second laser plane signal around a second rotating shaft which is vertical to the first rotating shaft; the to-be-positioned marking device synchronizes the standard time from the positioning base station and detects the supersonic wave signal, the first laser plane signal and the second laser plane signal; the calculating device is used for determining a three-dimensional space coordinate of the to-be-positioned marking device according to the time of the to-be-positioned marking device detecting the supersonic wave signal, the time of the same detecting the first laser plane signal and the time of the same detecting the second laser plane signal. The system and the method can realize indoor precision positioning based on the supersonic wave signal and the laser signals.

Description

technical field [0001] The invention relates to positioning technology, in particular to a three-dimensional space detection system, a positioning method and a system. Background technique [0002] With the development of mobile devices and network technologies, location-based services are becoming more and more important in people's lives. Current positioning can be divided into outdoor positioning and indoor positioning according to different positioning areas. Among them, outdoor positioning is mainly realized through a satellite positioning system, and the current outdoor positioning technology can well meet the requirements of outdoor positioning. However, when positioning indoors, due to the limitations of positioning time, positioning accuracy, and complex indoor environments, outdoor positioning technology cannot meet the needs of users when it is applied to indoor positioning. [0003] In order to realize indoor positioning, existing solutions, for example, use te...
