Data acquisition and analysis method, system and device fusing UWB and IMU

Abstract

The invention discloses a UWB and IMU fused data acquisition and analysis method, system and device. The method comprises the steps of obtaining left foot positioning data and right foot positioning data corresponding to each moment according to UWB data of a left foot and UWB data of a right foot; according to the IMU inertial navigation data of the left foot and the IMU inertial navigation data of the right foot, actions of the left foot and actions of the right foot corresponding to all moments are obtained; obtaining left foot positioning data, left foot ice pedaling data and left foot sliding data corresponding to all moments according to the actions of the left foot; obtaining right foot positioning data, right foot ice pedaling data and right foot sliding data corresponding to each moment according to the action of the right foot; the left foot positioning data, the left foot ice pedaling data and the left foot sliding data corresponding to all the moments are combined in sequence according to the moments and displayed; and sequentially combining the right foot positioning data, the right foot ice pedaling data and the right foot sliding data corresponding to the moments according to the moments, and displaying. According to the method, the actions and states of the athletes at all moments can be objectively judged.

Description

technical field [0001] The invention relates to the technical field of wireless UWB positioning and communication, in particular to a data acquisition and analysis method, system and device that integrate UWB and IMU. Background technique [0002] At present, the means of data collection in speed skating (including short track and avenue) events in training is relatively simple. The timing equipment is mainly used to evaluate the sliding results of the athletes. If further analysis is made relative to the sliding process, the only way to collect the sliding data is through video. The picture, the specific analysis can only be based on the subjective experience of the coach, and it is impossible to objectively give key data such as the speed and direction, acceleration and direction, force and direction of each point during taxiing, as well as the accurate trajectory during taxiing (for Analyze whether the athlete's cornering and traveling route are reasonable). [0003] To ...
