Title:
THREE-DIMENSIONAL WIRELESS OPTICAL POSITIONING METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/029028
Kind Code:
A1
Abstract:
Disclosed are a three-dimensional wireless optical positioning method and system. The method comprises the following steps: providing two LED lamps that emit light information and are used for illumination on a ceiling, and providing a receiver comprising two photoelectric detectors on a receiving plane; respectively calculating the distances from the LED lamps to the photoelectric detectors by means of a time of arrival (TOA) method; determining, according to the geometrical relationship of the LED lamps and the photoelectric detectors in an XYZ coordinate system, that the distance between the two photoelectric detectors is 1 and the two photoelectric detectors are in the same receiving plane, the receiver is below the two LED lamps, and a range to be positioned is located on any side of a plane consisting of the two LED lamps and the origin, and finally determining the actual position and the direction angle of the receiver. According to the present invention, three-dimensional positioning and orientation of a terminal are achieved while illuminating, accurate indoor three-dimensional positioning is still achieved under the condition that the number of optical transmitters is reduced, and the actual orientation situation of the terminal is accurately determined.
