Title:
METHOD AND SYSTEM FOR POSITIONING DEVICE BY USING LIGHT BEAM
Document Type and Number:
WIPO Patent Application WO/2023/016405
Kind Code:
A1
Abstract:
A method and system for positioning a device by using a light beam, and a storage medium and an electronic device. At least three optical receivers are arranged on a device, and the three optical receivers are not collinear. The method comprises: receiving, by means of optical receivers on a device, one or more light beams that are transmitted by an optical transmitter, wherein each light beam is encoded with transmission angle information of the light beam relative to the optical transmitter; decoding the light beam that is received by the optical receiver, so as to obtain the transmission angle information of the light beam; on the basis of the transmission angle information of the one or more light beams that are received by each optical receiver, determining direction information of the optical receiver relative to the optical transmitter; and on the basis of the relative positional relationship between the optical receivers on the device and the direction information of each optical receiver relative to the optical transmitter, determining position and/or posture information of the device relative to the optical transmitter. The system comprises an optical transmitter and a device. The storage medium stores a computer program, and the method is implemented when the computer program is executed by a processor. The electronic device comprises a processor and a memory, wherein the memory stores a computer program.
