【摘要】： 視覺是人類最重要的感覺之一,平面顯示技術(shù)基本滿足了視覺需求,但是其顯示的圖像缺乏真實立體感,不符合人眼觀察周圍事物的習慣。正因為如此,人們越來越不滿足平面顯示的限制,開始研究真正的三維顯示技術(shù)。 體三維顯示是三維顯示領(lǐng)域最前沿的一種解決方案,不同于傳統(tǒng)的三維顯示,它在透明體空間內(nèi)顯示圖像,包含景物的高度、寬度及深度,最為符合人眼視覺特征。其最大的優(yōu)點就是可以直接觀察,無需佩戴眼鏡等輔助設施,并且允許多人,多角度同時觀察。在航空管制、CAD/CAM、輔助醫(yī)療診斷、廣告、家庭娛樂等領(lǐng)域有著廣闊的應用前景。對體三維顯示的研究得到了國家“863”的支持,前期的顯示平臺獲得了專家的一致好評。而本文主要針對原系統(tǒng)的不足提出了一個新的解決方案,最后設計、實現(xiàn)。 文章首先對體三維相關(guān)技術(shù)做了詳細的分析,從理論出發(fā)研究了體三維顯示系統(tǒng)的原理和框架,按功能把系統(tǒng)分成了三個子系統(tǒng),并詳細闡述了每個子系統(tǒng)的功能和性能要求。隨后提出了具體的實現(xiàn)方案,即采用投影面旋轉(zhuǎn)構(gòu)成圓柱形成像空間,利用目前空間光調(diào)制器領(lǐng)域最先進的數(shù)字微鏡配合投影系統(tǒng)構(gòu)成了體素激活系統(tǒng),并設計了功能完善的體三維引擎把整個系統(tǒng)連接起來,完成了實際物理平臺。 課題研究的主要成果是提出了利用數(shù)字微鏡的快速開關(guān)特性實現(xiàn)體顯示的方案,設計了針對體三維顯示系統(tǒng)的點、線繪制算法,坐標系統(tǒng)、頂點格式,推導出了模型切片算法、坐標映射算法,最后結(jié)合以上成果搭建了體三維顯示平臺。實驗結(jié)果證明系統(tǒng)達到了設計的要求,驗證了體三維顯示的相關(guān)理論,并且性能優(yōu)于前期的平臺。文章最后針對實驗中出現(xiàn)的問題和不足,提出了相應的解決方案,為下一步發(fā)展奠定了堅實的基礎(chǔ)。
[Abstract]:Vision is one of the most important sensations of human beings. Plane display technology basically meets the needs of vision, but the images it displays lack of realistic three-dimensional sense, which does not accord with the habit of observing things around the human eyes. Because of this, people are less and less satisfied with the restriction of plane display and begin to study the real 3D display technology. Volume 3D display is the most advanced solution in the field of 3D display, which is different from traditional 3D display. It displays images in transparent body space, including the height, width and depth of the scene, which is most in line with the human visual characteristics. Its greatest advantage is that it can be observed directly, without wearing glasses and other auxiliary facilities, and allows multiple people, multiple angles to observe at the same time. In CAD / CAM, auxiliary medical diagnosis, advertising, home entertainment and other fields have a broad application prospects. The research on 3D display has been supported by national "863", and the previous display platform has been well received by experts. This paper proposes a new solution to the shortcomings of the original system, and finally designs and implements it. In this paper, the theory and framework of volume 3D display system are analyzed in detail. The system is divided into three subsystems according to its function, and the function and performance requirements of each subsystem are described in detail. Then a specific scheme is put forward, that is, the cylindrical imaging space is made up of projective plane rotation, and the voxel activation system is constructed by using the most advanced digital micromirror and projection system in the field of space light modulator. The whole system is connected with the body three-dimensional engine with perfect function, and the actual physical platform is completed. The main achievement of this paper is to put forward a scheme to realize volume display by using the fast switching characteristic of digital micromirror, to design the point, line drawing algorithm, coordinate system, vertex format for volume 3D display system, and to deduce the model slicing algorithm. Coordinate mapping algorithm, finally combined with the above results to build a volume three-dimensional display platform. The experimental results show that the system meets the design requirements and verifies the theory of volume 3D display and its performance is superior to that of the previous platform. Finally, aiming at the problems and shortcomings in the experiment, the corresponding solutions are put forward, which lays a solid foundation for the further development.
