Embodiment Construction

[0065] The method of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0066] Such as figure 1 Shown, a kind of human body pose comparison method based on Kinect skeletal node position tracking in the present embodiment is characterized in that: comprise the following steps:

[0067] Step 1. Connect the USB port of the Kinect V2 hardware to the USB3.0 interface of the notebook to ensure that the depth data and color data scanned by the device can be transmitted normally, and the bone node data automatically calculated by the KinectV2 hardware in Unity3D through the KinectSDKWrapper script To receive and store, connect the USB port of Microsoft’s product KinectV2 hardware to the USB3.0 interface of the notebook, and download the corresponding version of the driver KinectStadio V2.0 through the official website of Microsoft, which can collect the user’s depth data through the device. Combined with th...

Abstract

The invention particularly relates to a human gesture comparison method based on Kinect bone node position tracking, which mainly solves the shortcomings of data stability and data real-time in the prior bone node position positioning and user gesture comparison methods. The invention firstly saves a batch of data close to the time by using a dynamic frame number replacement algorithm, as the datasource of node filtering, then, the improved median filtering algorithm is used to filter and predict the adaptive intercepted data, and the stable and real-time filtering points are outputted to calculate the bone angle and the bone vector product angle of the user. Finally, the bone angle and the bone vector product angle are smoothed as the basis of evaluating the user's action. This method issuitable for filtering and smoothing the time-dependent continuous variable, tracking the user's posture in virtual reality games, and monitoring and measuring the dynamic change of device angle in engineering.

Description

technical field [0001] The invention belongs to the technical field of real-time comparison methods for multi-user body movements. Specifically, a human pose comparison method based on Kinect bone node position tracking is proposed. This method can also be applied to the tracking of user posture in virtual reality games, and the monitoring and measurement of dynamic changes in device angles in engineering. Background technique [0002] Virtual reality technology (Virtual Reality, VR) is a computer technology that can create and experience virtual worlds. It is an advanced human-machine interface based on immersion, interaction and imagination. . It uses computers to generate a virtual environment, and by simulating the actual situation, it affects people's sense organs such as touch, hearing, and vision, so that people can immerse themselves in the virtual world generated by computers. At the same time, with the help of professional equipment such as sensor helmets, motio...
