Problems solved by technology
[0006] However, the motion data obtained by the inertial sensors of smart shoes in various sports modes such as slow walking, jogging, and fast running are quite different. The recognition of the touch action produces an error
Specifically, the existing smart shoes can only accurately identify and process the exercise data of one of the exercise modes, but cannot accurately identify and process the exercise data of all exercise modes. When the user switches to other exercise modes, for example, from If you switch from slow walking to fast running, you will not be able to accurately identify the touchdown action during fast running, and it is easy to identify mistakes, which will have a great impact on the precise calculation of step counting, posture capture, and motion pattern analysis.

The invention provides a ground touching action recognition method and a storage medium. The method comprises the following steps: acquiring three-axis acceleration data acquired by an inertial sensor; constructing a time sequence for the three-axis acceleration data arranged according to the time sequence, and starting a sliding window with a fixed time length to obtain a local sequence from the time sequence; modeling in all acceleration data of the local sequence to form change models corresponding to the acceleration of each axis so as to reflect data characteristics corresponding to each change model, and judging whether a model set formed by at least one change model is matched with a preset grounding model corresponding to the model set or not based on the data characteristics, if so, triggering a grounding instruction representing that the grounding action is detected; and sending the grounding instruction to terminal equipment which is in wireless connection with the local machine. The ground touching action recognition method can accuratelyrecognizethe ground touching action of the user in different motion modes.
Description
technical field [0001] The present invention relates to the technical field of motion recognition, in particular to a ground-touching motion recognition method and a computer storage medium. Background technique [0002] In recent years, with the rise of intelligent sports and somatosensory games, motion analysis through human body posture and action data and control of posture changes or special effects output of characters in somatosensory games through human body posture and movement data have attracted more and more attention from the public. [0003] At present, in order to completely capture various postures and movements of the human body, motion capture is usually performed by camera technology to obtain various postures and movements of the human body in real time. However, motion capture by camera technology is only applicable to indoor environments, and general users do not have the material conditions to arrange multiple cameras for motion capture. Therefore, th...
