Title:
MULTI-IMU DATA ALIGNMENT AND PACKET LOSS COMPENSATION METHOD AND SYSTEM AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/109248
Kind Code:
A1
Abstract:
The present application discloses a multi-IMU data alignment and packet loss compensation method. The method comprises the following steps: acquiring motion data streams of different parts of a user by means of a plurality of IMU sensors; enabling the sampling frequency of each IMU sensor to be the same; aligning initial data in each motion data stream; and when any motion data stream experiences packet loss, aligning the packet loss data in the motion data stream with the corresponding data in other motion data streams. The present application further discloses a multi-IMU data alignment system. According to the multi-IMU data alignment and packet loss compensation method and system and the medium of the present application, the initial data of each motion data stream are aligned and the data experiencing packet loss are re-aligned, so that the data sent by the plurality of IMU sensors in most cases are aligned, and subsequent application of the data is facilitated.
