Title:
METHOD FOR ACQUIRING POSE INFORMATION AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/160978
Kind Code:
A1
Abstract:
A method for acquiring pose information and an electronic device (100), which relate to the field of smart homes and can reduce the error between measured pose information and actual pose information, thus increasing the accuracy of pose measurement. The electronic device (100) comprises a UWB chip and n antennas for constructing a carrier antenna coordinate system, n≥3. The coordinate origin of the carrier antenna coordinate system is located at the position at which an antenna 0 among the n antennas is located. An antenna i is located on the coordinate axis of the carrier antenna coordinate system. The distance between the antenna i and the antenna 0 is less than or equal to λ, λ is the wavelength of a UWB signal, and i is sequentially a value in {1, 2, ..., n-1}. The electronic device (100) receives, by means of the n antennas, UWB signals from m UWB base stations, m≥3 and m being an integer; and spatial pose information of the electronic device (100) is determined according to the received UWB signals. The spatial pose information of the electronic device (100) comprises the pitch angle, azimuth angle, and roll angle of the carrier antenna coordinate system relative to a UWB coordinate system.
