【摘要】： 隨著科學(xué)技術(shù)的高速發(fā)展以及信息量的急速膨脹,在大規(guī)模信息可視化、虛擬現(xiàn)實(shí)和仿真、數(shù)字影院、展覽展示、會(huì)議及教育等諸多領(lǐng)域,人們對(duì)顯示技術(shù)的要求越來(lái)越高。主要需求表現(xiàn)為高的分辨率、大的顯示尺寸和強(qiáng)的沉浸感。由于單臺(tái)投影儀支持分辨率有限,對(duì)多臺(tái)投影儀輸出畫(huà)面進(jìn)行拼接來(lái)構(gòu)建多投影顯示系統(tǒng)已經(jīng)成為一個(gè)備受關(guān)注的研究熱點(diǎn)。 目前多投影顯示系統(tǒng)根據(jù)實(shí)現(xiàn)方式可分為硬件實(shí)現(xiàn)和軟件實(shí)現(xiàn)。專(zhuān)業(yè)硬件產(chǎn)品處理能力強(qiáng),系統(tǒng)可伸縮性好,但往往針對(duì)一種應(yīng)用場(chǎng)合,價(jià)格不菲。國(guó)內(nèi)外研究小組開(kāi)發(fā)的多投影顯示系統(tǒng)在非專(zhuān)業(yè)硬件基礎(chǔ)上利用軟件實(shí)現(xiàn)各種功能,例如幾何和顏色校正,邊緣融合,遠(yuǎn)程交互等。軟件實(shí)現(xiàn)往往系統(tǒng)功能豐富,價(jià)格低廉。目前,基于專(zhuān)業(yè)硬件的多投影系統(tǒng)的主要問(wèn)題為：對(duì)于VGA模擬信號(hào),系統(tǒng)缺乏對(duì)VGA采集信號(hào)進(jìn)行高質(zhì)量的顏色校正,難以消除多投影拼接畫(huà)面色度和亮度的不一致；缺乏對(duì)每類(lèi)應(yīng)用進(jìn)行靈活配置,多配置間難以動(dòng)態(tài)切換；當(dāng)系統(tǒng)輸入信號(hào)種類(lèi)較多,每類(lèi)包含大量的信號(hào)采集窗口時(shí),現(xiàn)有系統(tǒng)未提供面向任務(wù)的多窗口管理機(jī)制。 本文給出了一套基于多窗口管理的多投影顯示系統(tǒng)。與現(xiàn)有基于專(zhuān)業(yè)硬件的多投影系統(tǒng)相比,本文系統(tǒng)具有如下優(yōu)勢(shì)： ●利用軟件方式實(shí)現(xiàn)系統(tǒng)的各種功能,擴(kuò)展性較好,且系統(tǒng)采用非專(zhuān)業(yè)硬件,系統(tǒng)成本較專(zhuān)業(yè)硬件產(chǎn)品價(jià)格低。 ●內(nèi)置多個(gè)處理模塊,能對(duì)采集得到的信號(hào)數(shù)據(jù)進(jìn)行相關(guān)處理。模塊與模塊之間能自由組合成處理流水線。另外,能動(dòng)態(tài)管理信號(hào)處理所需參數(shù),對(duì)同一類(lèi)型參數(shù)提供多套配置,并能在多配置之間動(dòng)態(tài)切換。 ●提供類(lèi)似于Windows的系統(tǒng)桌面和任務(wù)欄,用戶通過(guò)簡(jiǎn)單的鼠標(biāo)操作即可實(shí)現(xiàn)復(fù)雜的布局管理。提供應(yīng)用場(chǎng)合配置管理功能,支持多個(gè)應(yīng)用場(chǎng)合以及應(yīng)用場(chǎng)合之間的動(dòng)態(tài)切換。 實(shí)驗(yàn)數(shù)據(jù)和實(shí)際應(yīng)用表明本文系統(tǒng)能在主流硬件環(huán)境下實(shí)現(xiàn)對(duì)各類(lèi)外接信號(hào)源的實(shí)時(shí)捕獲,在大部分應(yīng)用場(chǎng)合下繪制達(dá)到實(shí)時(shí)水平。面向任務(wù)的多窗口控制端簡(jiǎn)化了用戶操作,提高了系統(tǒng)的可用性。
[Abstract]:With the rapid development of science and technology and the rapid expansion of information, there are many fields such as large-scale information visualization, virtual reality and simulation, digital cinema, exhibition, conference and education, etc. The demand for display technology is becoming higher and higher. The main requirements are high resolution, large display size and strong immersion. It has become a hot topic to construct multi-projection display system by splicing the output images of multiple projectors. At present, the multi-projection display system can be divided into hardware implementation and software implementation according to the implementation mode. The professional hardware product has strong processing ability and the system is scalable, but it is often aimed at a kind of application situation. The multi-projection display system developed by research groups at home and abroad uses software to realize various functions on the basis of non-professional hardware, such as geometric and color correction, edge fusion, remote interaction, etc. At present, the main problems of multi-projection system based on professional hardware are as follows: for VGA analog signal, the system lacks of high quality color correction for VGA acquisition signal, so it is difficult to eliminate the inconsistency between color and brightness of multi-projection splicing images; There is a lack of flexible configuration for each class of applications, and it is difficult to dynamically switch between multiple configurations. When there are more types of input signals and each class contains a large number of signal acquisition windows, the existing system does not provide a task-oriented multi-window management mechanism. This paper presents a multi-projection display system based on multi-window management. Compared with the existing multi-projection system based on professional hardware, the system has the following advantages:. Using software to realize various functions of the system, the system has good expansibility, and the system adopts non-professional hardware, and the cost of the system is lower than that of the specialized hardware products. Built in multiple processing modules, can collect the signal data processing. Modules and modules can be freely combined into processing pipeline. In addition, can dynamically manage the parameters required for signal processing, Provides multiple configurations for the same type of parameters and can dynamically switch between multiple configurations. Provides the system desktop and taskbar similar to Windows, the user can realize the complex layout management through the simple mouse operation, provides the application situation configuration management function, supports the multi-application situation and the application situation dynamic switching. Experimental data and practical application show that the system can capture all kinds of external signal sources in the mainstream hardware environment in real time. In most applications, rendering reaches real-time level. Multi-window control for task simplifies user operation and improves the usability of the system.
