基于Kinect体感交互的多人在线虚拟实验系统

为了满足多人异地进行真实感虚拟实验的需求,使用Kinect体感设备和Unity 3D引擎搭建了一个多人在线虚拟实验系统。在该系统中,使用Unity 3D引擎搭建虚拟实验场景,通过导入3D Max制作的实验器材模型进行实验搭建,并通过网络通信技术实现远距离多人在线操作。对于真实感部分,采用Kinect体感技术捕捉的身体姿势被用来控制虚拟场景中第一人称角色的走动、抓取和操作实验器材以及选取虚拟场景中的菜单。实验结果证明,Kinect姿势识别具有很高的准确性和鲁棒性,并且不容易被光照条件和复杂的背景所影响,服务器与客户端的通信对于建立远程虚拟实验系统来说足够稳定。该系统具有成本低、真实感较强的优点。

Multiplayer Online Virtual Experiment System Based on Kinect Somatosensory Interaction

In order to meet the needs of allowing more than one person conducting a certain virtual experiment at the same time in different places,we proposed a multiplayer online virtual experiment system built by Kinect somatosensory equipment and Unity 3D engine.In this system,the virtual experiment scenes are built by Unity 3D engine and experimental equipments are made by using 3D Max which is well-known as a modeling software.The multi-player online function is completed by the network communication technology.To make users feel real,the body gesture caught by Kinect somatosensory technology can be used to control first-person-character to walk around,grab experimental equipments and manipulate the menu in the virtual scene.The practical result shows that the Kinect gesture recognition has good accuracy and robustness,and is hardly affected by light situations and complex background.At the same time,the communication between the server and client is stable enough to build a remote virtual experiment system,and the system can achieve a high immersion with lower cost.
