【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)實和仿真、數(shù)字影院、展覽展示、會議及教育等諸多領(lǐng)域,人們對顯示技術(shù)的要求越來越高。主要需求表現(xiàn)為高的分辨率、大的顯示尺寸和強的沉浸感。由于單臺投影儀支持分辨率有限,對多臺投影儀輸出畫面進(jìn)行拼接來構(gòu)建多投影顯示系統(tǒng)已經(jīng)成為一個備受關(guān)注的研究熱點。 目前多投影顯示系統(tǒng)根據(jù)實現(xiàn)方式可分為硬件實現(xiàn)和軟件實現(xiàn)。專業(yè)硬件產(chǎn)品處理能力強,系統(tǒng)可伸縮性好,但往往針對一種應(yīng)用場合,價格不菲。國內(nèi)外研究小組開發(fā)的多投影顯示系統(tǒng)在非專業(yè)硬件基礎(chǔ)上利用軟件實現(xiàn)各種功能,例如幾何和顏色校正,邊緣融合,遠(yuǎn)程交互等。軟件實現(xiàn)往往系統(tǒng)功能豐富,價格低廉。目前,基于專業(yè)硬件的多投影系統(tǒng)的主要問題為：對于VGA模擬信號,系統(tǒng)缺乏對VGA采集信號進(jìn)行高質(zhì)量的顏色校正,難以消除多投影拼接畫面色度和亮度的不一致；缺乏對每類應(yīng)用進(jìn)行靈活配置,多配置間難以動態(tài)切換；當(dāng)系統(tǒng)輸入信號種類較多,每類包含大量的信號采集窗口時,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： ●利用軟件方式實現(xiàn)系統(tǒng)的各種功能,擴(kuò)展性較好,且系統(tǒng)采用非專業(yè)硬件,系統(tǒng)成本較專業(yè)硬件產(chǎn)品價格低。 ●內(nèi)置多個處理模塊,能對采集得到的信號數(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,能動態(tài)管理信號處理所需參數(shù),對同一類型參數(shù)提供多套配置,并能在多配置之間動態(tài)切換。 ●提供類似于Windows的系統(tǒng)桌面和任務(wù)欄,用戶通過簡單的鼠標(biāo)操作即可實現(xiàn)復(fù)雜的布局管理。提供應(yīng)用場合配置管理功能,支持多個應(yīng)用場合以及應(yīng)用場合之間的動態(tài)切換。 實驗數(shù)據(jù)和實際應(yīng)用表明本文系統(tǒng)能在主流硬件環(huán)境下實現(xiàn)對各類外接信號源的實時捕獲,在大部分應(yīng)用場合下繪制達(dá)到實時水平。面向任務(wù)的多窗口控制端簡化了用戶操作,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.
