Digital Micro-mirror Device (DMD) is used as the Spatial Light Modulator (SLM) and an algorithm is designed for binary slice projection based on DMD. An approach for volumetric space creation based on a rotating helical screen is also adopted. Furthermore, a hand gesture control-based HCI subsystem for the prototype is designed and implemented. Experimental results demonstrate that, a data reduction of more than 40% is achieved through utilizing BCC sampling strategy, and objects can be displayed with true three dimensions at a refresh rate of 16Hz in a half-cylinder display space with a diameter of 500mm and a height of 250mm, and can be viewed from almost any angle without any special viewing aids. With the hand gesture control subsystem, the average recognition rate is as high as 93%, the average response time is less than 40ms, and the real-time interactions can be well performed from an arbitrary viewpoint., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null,

articleAbstract=研究了交互式动态体三维显示的关键技术，包括三维数据体素化、体素激活、体空间生成和人机交互等，实现了体三维显示系统样机。其中，采用体立方栅格（BCC）采样策略以减少体素化生成的体显示数据，以数字微镜器件（DMD）作为空间光调制器（SLM），并针对DMD设计了二值切片的快速激活算法；分析了基于旋转螺旋面的体三维空间生成方法，并将基于隐马尔科夫模型（HMM）的动态手势控制应用于交互式体三维显示系统。针对原理样机设计的各组实验表明，BCC体素化策略减少了40%以上的体显示数据，基于DMD的切片快速激活算法使得在500mm×250mm半圆柱形成像空间内显示的三维图像刷新率达16Hz、并且可以选择任意视点裸眼观看，准确率超过93%、响应时间低于40ms的动态手势识别算法能够较好地实现实时交互式体三维显示。,
