Embodiment

[0050] Such as figure 1 As shown, the Kinect-based badminton action guidance system of the present embodiment includes a preprocessing module, a similarity measurement module, and an action evaluation display module.

[0051] Wherein, the preprocessing module adopts Microsoft's kinect somatosensory device, and uses kinectSDK to track the user's actions to obtain the skeleton features of the human body; the skeleton features include global torso features and local joint point features;

[0052] The similarity measurement module is used to match the acquired user's skeleton features with the skeleton features of standard badminton actions for similarity measurement;

[0053] The action evaluation and display module compares the distance between the user action posture obtained by the similarity measurement module and the standard action posture matching action time period, so as to obtain the distance difference between each joint point corresponding to the user action and the s...

Abstract

The invention discloses a Kinect-based badminton action guidance system, which includes a preprocessing module, adopts Microsoft's kinect somatosensory device, tracks user actions through kinect SDK, and obtains skeleton features of the human body; Matching with the skeleton features of standard badminton actions to measure the similarity; the action evaluation and display module compares the distance between the user action posture obtained by the similarity measurement module and the action time period that matches the standard action posture, so as to obtain the user action and the standard action. The distance difference between each joint point at the corresponding position of the sequence, and the result is displayed on the screen. In the present invention, the user does not need to wear clothes with sensors, and at the same time, he / she can follow the video self-help to learn the standard action of badminton without the need of a coach, thereby improving the accuracy of his badminton swing.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to a Kinect-based badminton action guidance system. Background technique [0002] With the technical update of depth cameras, these cameras can already be applied to the current high-complexity computer vision tasks. With its help, the difficulty of vision-based pose estimation has been greatly reduced. Therefore, a number of invention patents have been proposed in the field of human action recognition. For example, patent CN106573665A adopts the Vibit algorithm to perform action recognition, and CN104408461A adopts the method of sliding window local matching window to perform action recognition. And in the field of motion guidance, there is CN103706106A through the method for Kinect adaptive motion training. But it can be said that there is a lack of patents for optimizing and developing a certain specific environment (such as learning badminton actions) in the field of...
