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 motion guidance system, which comprises a pre-processing module, a similarity measurement module, and a motion evaluation and display module. The pre-processing module adopts Microsoft's kinect motion sensing equipment, tracks user motions through a kinectSDK, and obtains skeleton features of a human body; the similarity measurement module matches the obtained skeleton features of the human body with skeleton features of standard badminton actions and carries out similarity measurement; the motion evaluation and display module carries out distance comparison on a motion time period (during which user motion poses are matched with standard motion poses) obtained by the similarity measurement module, so as to obtain distance differences between joint points at corresponding positions of user motions and a standard notion sequence, and displays results on a screen. According to the Kinect-based badminton motion guidance system, the user does not need to wear clothes provided with sensors, and can learn badminton standard motions by following videos in a self-aid manner under the condition without a coach, thereby improving accuracy of badminton racket swinging motions of the user.

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...
