Research On Multi-view Motion Capture Method For Virtual Interactive System

Mobile Internet,computer technology and related hardware supporting industries are developing rapidly.This has driven the development of a large number of motion capture devices,such as depth cameras.Advanced motion capture technology has also revolutionized traditional human-computer interaction technology.Virtual reality(VR)technology combined with motion capture technology can interact with the user's movement and body information while transmitting image information to the user.Based on this technology,a large number of VR applications have emerged,such as simulated driving training,simulated flight training and 3D games.With the development of the sports industry,more and more cutting-edge technologies are trying to be applied to sports training,such as VR.This thesis is oriented to the virtual basketball training scenario,and the multi-view motion capture system and VR interactive system are launched for in-depth research,mainly including:1.Traditional computer vision motion capture devices have poor tracking accuracy in blocking situations.To address this problem,this thesis proposes a multi-view motion capture method based on depth camera.This method combines multiple depth cameras to track targets from different perspectives,which effectively reduces the cost and improves tracking performance of monocular depth camera method.This method is applied to virtual training scenes.Multiple depth cameras are used to capture the target action from different perspectives,and then the action data from different perspectives are processed.Finally,the tracking performance of the traditional depth camera method is improved.The verification and implementation of the proposed system prove that the motion capture capability of the system is improved compared with the traditional monocular depth camera motion capture system.2.In response to the demand of multi-user off-site interaction in virtual training,this thesis implements a virtual interaction module.Using Unity3D software and Photon Server,this thesis creates a VR scene and designs a user interaction mechanism to realize a system that supports multiple users to train together online,which effectively extends the application scope of VR training system.This module uses Unity3D to develop VR basketball court and virtual single-player off-line interaction mechanisms such as dribbling and shooting.Then Photon Server is used to realize a multi-user remote login system and multi-user interaction Passing mechanism.Through the above steps,the module realizes the function of supporting remote online interaction of multiple people in the same VR space.Finally,the proposed module is verified,and the result proves the effectiveness of the multi-person interaction function of the module.
