可攜式多面投影立體懸浮顯示系統的建置與分析

Abstract

本論文建置了一台可攜式多面投影立體懸浮顯示系統，利用偏心菲涅爾投影透鏡成功的將多工影像源整合在單一面板上，解決了傳統空間多工立體投影顯示系統體積龐大且多工影像亮度不均的問題，同時也讓影像軌道的孔徑光欄產生本質上的相連，使本立體顯示系統具有影像和視域大小可調變的特性，此外，多面式環繞的設計讓立體影像產生懸浮的效果，提升立體影像的真實性。除了立體顯示系統的建置，吾等也建構了匹配於此立體顯示系統的模擬，能夠協助影像與視域分布的分析，若要提升修改或提升此立體顯示系統都能以此模擬作為基礎進行預測和變更。未來，若能將本論文所提及的偏心概念結合於光學微機電的元件中，將可以時間多工的形式微型化投影式立體顯示系統，同時再將懸浮影像結合立體深度辨識更可達成使用者與立體影像互動的真實感。

A portable multiplanar projective stereoscopic floating (PMPSF) display that solves the problems of large volume and nonuniform image illumination in traditional multiplexed projective 3D displays is proposed in this research. The usage of decentric Fresnel lenses successfully integrates all the image sources on just a single display board not only shrinking the volume of the stereoscopic display system but also making the field stops of all image tracks intrinsically connected with each other, which enables the images and viewing zones to be adjusted. Furthermore, the surrounding multiplanar design with a transparent pyramid plate generating the floating effect enhances the reality of stereoscopic images. In addition, the simulation which is capable of assisting the analysis of images and viewing zones of the PMPSF system is constructed as well, and it can be the basis for any further improvements or modifications of the PMPSF system. In the future, the concept of decentering proposed in this research can be combined with optical MEMS devices to miniature projective stereoscopic display system in a time-multiplexed form, and it can be further possible to achieve the 3D interaction between images and users by combining depth identification with floating images.
