Abstract: A method includes a device in an area 1 that requests a ultra-wideband (UWB) base station in the area 1 to measure an initial position, and starts inertial measurement unit (IMU) measurement. The device moves to an area 2, and the device requests to measure distances between each UWB base station in the area 2 and at least three locations. The device returns to the area 1, and requests the UWB base station in the area 1 to measure an end point position. The device corrects coordinates of the device in the area 2 calculated using data obtained through the IMU measurement based on the measured end point position. Calculate the coordinates of each UWB base station in the area 2 based on the corrected coordinates in the area 2 and the measured distances between each UWB base station and the device in the area 2.

Abstract: The electronic device includes an ultra-wideband (UWB) chip and n antennas configured to construct a carrier antenna coordinate system, where n≥3. A coordinate origin of the carrier antenna coordinate system is located at a location of an antenna 0 in the n antennas, an antenna i is located on a coordinate axis of the carrier antenna coordinate system, and a distance between the antenna i and the antenna 0 is less than or equal to λ, where λ is a wavelength of a UWB signal, and a value of i is sequentially obtained in {1, 2, . . . , n−1}. The electronic device receives UWB signals from m UWB base stations by using the n antennas, where m≥3, and m is an integer. Spatial posture information of the electronic device is determined based on the received UWB signals.

Abstract: A gesture recognition method and a related apparatus are provided, to obtain a first point cloud data set by filtering an original point cloud data set collected by a radar apparatus. The first point cloud data set includes a plurality of frames of first point cloud subsets, the first point cloud subset includes a first cluster center, the first cluster center is a cluster center of a plurality of pieces of point cloud data in the first point cloud subset, a maximum horizontal distance between any two first cluster centers meets a first preset condition, and duration of the first point cloud data set meets the first preset condition. Point cloud data whose motion track does not match gesture motion can be effectively filtered out. Gesture recognition is performed by using the first point cloud data set obtained by filtering.

Abstract: A method is implemented by an electronic device to mark a position of a home device. The method includes that the electronic device receives a first operation of a user, where the first operation is used to trigger the electronic device to mark a position of a first home device in a plurality of home devices. In response to the first operation, the electronic device obtains, by using a UWB chip, spatial position-attitude information of the electronic device when the electronic device separately points to the first home device in n orientations, and calculates spatial position information of the first home device based on the spatial position-attitude information of the electronic device in the n orientations.

Abstract: This application relates to a UWB base station anomaly detection method. The method includes: obtaining a first distance that is between each of the N UWB base stations and the UWB tag and that is obtained through measurement; obtaining an estimated value of spatial coordinates of the UWB tag in the first coordinate system based on the first distance and spatial coordinates of each UWB base station in the first coordinate system; obtaining a second distance between each UWB base station and the UWB tag based on the estimated value and the spatial coordinates of each UWB base station in the first coordinate system; and determining, based on the first distance and the second distance that correspond to each UWB base station, whether a UWB base station in the N UWB base stations is abnormal.
