【摘要】：隨著時(shí)代的發(fā)展,數(shù)字圖像技術(shù)越來越多地運(yùn)用到人類生活的方方面面,其中,投影技術(shù)更是在各種商業(yè)活動(dòng),大型展覽中遍地開花。與此同時(shí),由于數(shù)字科技的飛速發(fā)展和進(jìn)步,人們對(duì)視覺效果的欣賞水平和眼界也越來越高,尤其是近年來,投影效果產(chǎn)生了革命性的進(jìn)步,人們不斷追求亮麗的超大畫面,純真的色彩,高分辨率的顯示效果。大到指揮監(jiān)控中心,網(wǎng)管中心的建立,小到視頻會(huì)議,學(xué)術(shù)報(bào)告,技術(shù)講座和多功能會(huì)議室的進(jìn)行,對(duì)大畫面,多色彩,高亮度,高分辨率顯示效果的需求越來越強(qiáng)烈。而要達(dá)到更恢宏,氣勢(shì)磅礴的投影效果,就必須要采用多屏幕拼接的方法。于是,投影融合便成為一個(gè)至關(guān)重要的技術(shù)。但是,目前已有的投影融合技術(shù),依然有很多的不足,難以滿足市場(chǎng)的需要。其中高昂的成本使得只有大型商家在展會(huì)中才會(huì)使用,其必須使用融合機(jī)進(jìn)行融合的特點(diǎn)使得在需要長(zhǎng)期使用的情況下購買費(fèi)用和維護(hù)費(fèi)用都是居高不下的。投影融合技術(shù)是一個(gè)十分依賴硬件的技術(shù),隨著硬件的不斷更新?lián)Q代,如何利用現(xiàn)有的資源進(jìn)行最大效率的開發(fā),是否存在一種方法可以不需要融合機(jī)即可融合是目前行業(yè)內(nèi)急需解決的問題。2014年由我和團(tuán)隊(duì)完成的青島《尋夢(mèng)園》項(xiàng)目就遇到了這樣一個(gè)難題,我們要打造一個(gè)78米長(zhǎng)、4米高的動(dòng)畫投影,客戶要求美輪美奐的藝術(shù)效果與良好的投影融合效果,又提出預(yù)算有限,不能使用昂貴的融合機(jī)。為了解決這種問題,本文結(jié)合動(dòng)畫項(xiàng)目,基于GPU運(yùn)算開發(fā)了一種新的融合技術(shù)。即通過對(duì)程序框架的合理設(shè)計(jì),對(duì)融合原理的分析,將融合中需要的計(jì)算數(shù)據(jù)進(jìn)行分流,同時(shí)使用CPU和GPU對(duì)圖像進(jìn)行計(jì)算處理,充分發(fā)揮GPU并行計(jì)算快于CPU的特點(diǎn),在圖像小數(shù)據(jù)大計(jì)算量的情況下,將部分?jǐn)?shù)據(jù)移交GPU計(jì)算,達(dá)到充分利用硬件環(huán)境,節(jié)約資源,提高運(yùn)行效率的目的。最終,在藝術(shù)的呈現(xiàn)與技術(shù)的創(chuàng)新上,都交了一份令客戶滿意的答卷。
[Abstract]:With the development of the times, digital image technology is more and more used in all aspects of human life. Among them, projection technology is widely used in all kinds of commercial activities and large-scale exhibitions. At the same time, with the rapid development and progress of digital science and technology, the level of people's appreciation of visual effects and vision is also getting higher and higher, especially in recent years, projection effect has produced revolutionary progress, people continue to pursue bright large picture. Pure color, high resolution display effect. From the establishment of command monitoring center, network management center, video conference conference, academic report, technical lecture and multi-function conference room, the demand for large picture, multi-color, high brightness and high resolution display effect is more and more intense. In order to achieve a more magnificent, magnificent projection effect, we must adopt multi-screen splicing method. Thus, projection fusion becomes a crucial technology. However, the existing projection fusion technology, there are still a lot of deficiencies, difficult to meet the needs of the market. The high cost will only be used by large businesses in the exhibition, which must use the fusion machine for the characteristics of the need for long-term use of the case of purchase and maintenance costs are high. Projection fusion technology is a hardware-dependent technology, with the continuous upgrading of hardware, how to use existing resources for maximum efficiency development, Whether there is a way to fuse without the need for a fusion machine is a problem that needs to be solved in the industry. The Qingdao Dream Garden project, completed by my team and I in 2014, has encountered such a problem. We want to create a 78-meter long 4m high animation projection, the customer request beautiful artistic effect and good projection fusion effect, but also the budget is limited, can not use expensive fusion machine. In order to solve this problem, a new fusion technology based on GPU is developed in this paper. That is, through the reasonable design of the program framework and the analysis of the fusion principle, the computing data needed in the fusion is divided. At the same time, CPU and GPU are used to calculate and process the images, so that the parallel computation of GPU is faster than that of CPU. In the case of large computation of small image data, part of the data is transferred to GPU to achieve the purpose of making full use of hardware environment, saving resources and improving operation efficiency. Finally, in the presentation of art and technological innovation, have submitted a customer satisfaction.
