【摘要】：當(dāng)今社會(huì),人們已習(xí)慣用光與影來記錄與展示信息,信息顯示已成為各個(gè)領(lǐng)域不可或缺的生存發(fā)展手段之一。長(zhǎng)久以來,由于技術(shù)發(fā)展的局限性,在電影、電視、廣告屏等傳播媒介中,人們被局限于二維畫面。而人類所生存的世界是一個(gè)立體空間,所觀察到的事物具有高度、寬度和深度三個(gè)維度。相較于二維影像,三維影像與人類現(xiàn)實(shí)生活中習(xí)慣的場(chǎng)景更為一致,能帶給人們更逼真的感知與體驗(yàn)。因此,隨著微電子、光學(xué)、計(jì)算機(jī)等信息技術(shù)的飛速發(fā)展,在人們強(qiáng)大需求的推動(dòng)下,三維顯示技術(shù)成為當(dāng)今的研究熱點(diǎn)。體掃描三維顯示系統(tǒng)作為三維顯示技術(shù)實(shí)現(xiàn)的一種形式,它不但提供心理景深,還能呈現(xiàn)真實(shí)物理景深,是目前三維顯示技術(shù)研究中的重要方向。 本文以“三維體掃描顯示系統(tǒng)”課題的研究為背景,以提高“基于彩色LED陣列旋轉(zhuǎn)的體三維顯示系統(tǒng)”的分辨率、實(shí)時(shí)性,以及動(dòng)態(tài)性能為目標(biāo),主要圍繞系統(tǒng)架構(gòu)定義、顯示控制模塊設(shè)計(jì)、動(dòng)態(tài)顯示方案擬定以及系統(tǒng)穩(wěn)定性四個(gè)方面展開。 在分析系統(tǒng)工作原理的基礎(chǔ)上,圍繞本文提出的架構(gòu)定義,介紹了系統(tǒng)三維顯示裝置的功能結(jié)構(gòu)。 重點(diǎn)討論了其中顯示控制層模塊的設(shè)計(jì),提出并實(shí)現(xiàn)了基于Flash型FPGA的顯示控制模塊設(shè)計(jì)方案,同時(shí)引出基于動(dòng)態(tài)分配調(diào)色板、兼顧傳輸數(shù)據(jù)位寬與色彩細(xì)膩度的真彩顯示方案。 在動(dòng)態(tài)顯示方案擬定過程中,首次以“核心體處理單元”所處位置來定義體掃描三維顯示系統(tǒng),在分析本文綜述的“前端體處理系統(tǒng)”所存在問題的基礎(chǔ)上,提出了分布的嵌入式體處理思想,為實(shí)現(xiàn)動(dòng)態(tài)實(shí)時(shí)顯示提供了新途徑,而基于三角形網(wǎng)格的“電子幀像素集”生成算法的提出也為嵌入式體處理方案的實(shí)現(xiàn)打下了基礎(chǔ)。 從機(jī)械結(jié)構(gòu)、信號(hào)傳輸以及電子幀掃描與機(jī)械掃描同步三個(gè)方面分析了系統(tǒng)的穩(wěn)定性、可靠性問題,給出了相應(yīng)的優(yōu)化方案。
[Abstract]:Nowadays, people are used to record and display information with light and shadow. Information display has become one of the indispensable means of survival and development in all fields. For a long time, because of the limitations of technological development, in movies and television, In media such as advertising screens, people are confined to two-dimensional images. The world in which human beings live is a three-dimensional space, and the objects observed have three dimensions: height, width and depth. Three-dimensional images are more consistent with the familiar scenes in human real life, and can bring people more realistic perception and experience. Therefore, with the rapid development of information technology such as microelectronics, optics, computers and so on, driven by the strong demand of people, As a form of 3D display technology, it not only provides psychological depth of field, but also presents real physical depth of field. It is an important direction in the research of 3D display technology. Based on the research of "3D volume scan display system", this paper aims at improving the resolution, real-time and dynamic performance of "volume 3D display system based on color LED array rotation", which is mainly defined around the system architecture. Display control module design, dynamic display scheme formulation and system stability four aspects. Based on the analysis of the working principle of the system, the functional structure of the system 3D display device is introduced around the definition of the architecture proposed in this paper. The design of display control layer module is discussed in detail, and the design scheme of display control module based on Flash type FPGA is put forward and realized. At the same time, the design of display control module based on dynamic distribution palette is introduced. A true color display scheme that takes into account the bit width and color fineness of the transmission data. In the process of developing dynamic display scheme, the position of "core volume processing unit" is used for the first time to define the three-dimensional display system of volume scanning. Based on the analysis of the problems existing in "front-end volume processing system", which is summarized in this paper, The idea of distributed embedded volume processing is proposed, which provides a new way to realize dynamic real-time display. The algorithm of "electronic frame pixel set" generation based on triangle mesh also lays a foundation for the realization of embedded volume processing scheme. The stability and reliability of the system are analyzed from the aspects of mechanical structure, signal transmission and synchronization of electronic frame scanning and mechanical scanning, and the corresponding optimization scheme is given.
