摘　　要：大规模复杂场景中包含现实世界中的多种元素和交互方式,容易导致渲染和交互的延迟问题,影响用户体验。为此提出了虚拟现实技术下大规模复杂场景动态交互方法。利用Kinect相机和GPS系统获取用户手指在现实场景中的坐标位置,基于统一建模语言将手指坐标映射到大规模复杂虚拟场景中,以实时获得手指的虚拟场景坐标,根据手指间的位置关系得到用户的手势信息,并确定用户的交互操作需求,根据需求快速实现用户和大规模复杂虚拟场景的动态交互。实验结果表明,上述方法的易用性较高、交互效果较好。Large-scale complex scenes contain a variety of elements and interaction modes in the real world,which easily lead to the delay of rendering and interaction,affecting the user experience.Therefore,a dynamic interaction method for large-scale complex scenes based on virtual reality technology is proposed.The Kinect camera and GPS system are used to obtain the coordinate position of the user's fingers in the real scene,and the finger coordinates are mapped into large-scale complex virtual scenes based on the unified modeling language to obtain the virtual scene coordinates of the fingers in real time,obtain the user's gesture information according to the position relationship between the fingers,and determine the user's interactive operation needs,quickly realize dynamic interaction between users and largescale complex virtual scenes according to requirements.Experimental results show that the method is easy to use and has good interaction effect.
