提出基于Leap Motion手势识别的悬浮真3D显示实时交互系统,可实现对多个悬浮3D图像的独立交互。系统由显示和交互两个模块组成,显示模块利用集成成像3D显示屏再现3D图像,再通过二面角反射镜阵列实现悬浮真3D显示;交互模块通过Leap Motion识别手部各关节空间位置,提取手势信息并判断用户操作意图,利用提出的通道机制,独立改变3D场景内多个物体的空间坐标,渲染对应的3D片源并刷新,完成实时悬浮真3D显示交互,构成人机交互闭环系统。实验结果表明,该系统在3 840×2 160分辨率下,可实现30帧/s的交互帧率。所提系统通过预设手势可实现多物体的独立实时交互,提高了交互自由度。
A real-time floating 3D display interaction system is proposed, which can realize independent interaction of multiple floating 3D images. The proposed system consists of the display and interaction modules. In the display module, 3D images are reconstructed through integral imaging 3D display screen and then floats into the air through the dihedral corner reflector array. In the interaction module, Leap Motion captures positions of hand joints, extracts the gesture information and judges the motive of the users. After checking interaction channels, positions of multiple 3D objects are changed individually, and the 3D film source is rendered, which forms a human-computer interaction closed loop and realizes the real-time floating 3D display interaction. The experimental results demonstrate that the system can reach 30 frame/s under the resolution of 3 840×2 160. The real-time individual interaction of multiple objects can be achieved in the proposed system, and the interaction freedom is increased.
