【摘要】：近年來(lái),在虛擬現(xiàn)實(shí)技術(shù)基礎(chǔ)上發(fā)展而來(lái)的增強(qiáng)現(xiàn)實(shí)技術(shù)已經(jīng)成為計(jì)算機(jī)圖形圖像處理領(lǐng)域的一個(gè)研究熱點(diǎn),而隨著移動(dòng)計(jì)算技術(shù)的發(fā)展誕生了一門(mén)新興的技術(shù)——移動(dòng)增強(qiáng)現(xiàn)實(shí),即基于移動(dòng)終端的增強(qiáng)現(xiàn)實(shí)技術(shù)。目前,以智能手機(jī)為代表的移動(dòng)終端也獲得了迅速的發(fā)展,其具有的計(jì)算能力和圖形處理能力能與桌面計(jì)算機(jī)相媲美,加之其獨(dú)特的便攜性等優(yōu)勢(shì),基于移動(dòng)終端的增強(qiáng)現(xiàn)實(shí)系統(tǒng)在不斷發(fā)展。同時(shí),由于移動(dòng)終端自身硬件結(jié)構(gòu)的局限性,在用戶(hù)使用過(guò)程中的問(wèn)題也逐漸凸顯出來(lái),一方面,諸如手機(jī)、平板電腦等移動(dòng)終端產(chǎn)品的顯示屏幕無(wú)法呈現(xiàn)增強(qiáng)現(xiàn)實(shí)應(yīng)用中所需的沉浸感;另一方面,雖然手機(jī)、平板電腦等移動(dòng)終端產(chǎn)品中配備了陀螺儀、加速度計(jì)、攝像頭等傳感設(shè)備,但是用戶(hù)在使用的過(guò)程中需要手持,體驗(yàn)效果欠佳。此外,新型的交互技術(shù),如頭動(dòng)跟蹤技術(shù)要求傳感器獲取頭部動(dòng)作數(shù)據(jù),這在手機(jī)、平板電腦等移動(dòng)終端產(chǎn)品中無(wú)法實(shí)現(xiàn)。針對(duì)以上問(wèn)題,本文設(shè)計(jì)了一款與智能手機(jī)相結(jié)合的面向增強(qiáng)現(xiàn)實(shí)應(yīng)用的頭戴顯示器。該頭戴顯示器不僅能夠?qū)崿F(xiàn)增強(qiáng)現(xiàn)實(shí)應(yīng)用所需的沉浸感,而且能夠?qū)⒃鰪?qiáng)現(xiàn)實(shí)應(yīng)用所需采集的頭部動(dòng)作數(shù)據(jù)以及外界圖像信息發(fā)送給上位機(jī)。本文的內(nèi)容包括以下幾個(gè)方面:1)對(duì)頭戴顯示器進(jìn)行需求分析,在此基礎(chǔ)上提出了系統(tǒng)整體設(shè)計(jì)方案,完成了系統(tǒng)軟硬件平臺(tái)的方案設(shè)計(jì),并對(duì)硬件平臺(tái)的核心器件進(jìn)行了對(duì)比選型,對(duì)軟件平臺(tái)的功能和結(jié)構(gòu)進(jìn)行了介紹。2)在總體方案設(shè)計(jì)的基礎(chǔ)上,完成了頭戴顯示器硬件平臺(tái)的具體設(shè)計(jì)。主要包括采集模塊、攝像頭模塊、藍(lán)牙模塊、OLED微控制電路模塊、HDMI轉(zhuǎn)VGA模塊、電源模塊等。3)基于以上硬件平臺(tái),設(shè)計(jì)了頭戴顯示器驅(qū)動(dòng)程序,主要包括頭部動(dòng)作數(shù)據(jù)采集模塊、圖像采集模塊和OLED顯示模塊程序。4)在系統(tǒng)軟硬件平臺(tái)的基礎(chǔ)上設(shè)計(jì)了簡(jiǎn)單的增強(qiáng)現(xiàn)實(shí)程序,主要介紹了視覺(jué)跟蹤匹配模塊、圖形渲染、虛擬信息呈現(xiàn)與交互模塊軟件設(shè)計(jì)。5)對(duì)面向增強(qiáng)現(xiàn)實(shí)應(yīng)用的頭戴顯示器進(jìn)行了功能驗(yàn)證和測(cè)試,測(cè)試結(jié)果表明本次設(shè)計(jì)達(dá)到了預(yù)期的設(shè)計(jì)目標(biāo)。
[Abstract]:In recent years, the augmented reality technology developed on the basis of virtual reality technology has become a research hotspot in the field of computer graphics and image processing. With the development of mobile computing technology, a new technology, mobile augmented reality, is born, which is based on mobile terminal. At present, mobile terminals, represented by smart phones, have also gained rapid development. Their computing power and graphics processing ability are comparable to those of desktop computers, plus their unique advantages such as portability. The augmented reality system based on mobile terminal is developing continuously. At the same time, due to the limitations of the hardware structure of the mobile terminal itself, the problems in the process of using the mobile terminal have gradually become prominent. On the one hand, such as the mobile phone, On the other hand, mobile terminal products such as mobile phones and tablets are equipped with gyroscopes, accelerometers, cameras and other sensing devices. But the user needs handheld in the process of using, the experience effect is not good. In addition, new interactive technologies, such as head-tracking technology, require sensors to obtain head motion data, which cannot be achieved in mobile terminal products such as mobile phones and tablets. In view of the above problems, this paper designs a headset display for augmented reality application combined with smart phone. The head-mounted display can not only realize the immersion of the augmented reality application, but also send the head motion data and the external image information to the upper computer which need to be collected by the augmented reality application. The content of this paper includes the following aspects: 1) on the basis of analyzing the requirement of headwear display, the overall design scheme of the system is put forward, and the scheme design of the software and hardware platform of the system is completed. The core components of the hardware platform are compared and the function and structure of the software platform are introduced. On the basis of the overall scheme design, the hardware platform of head-mounted display is designed. Mainly including acquisition module, camera module, Bluetooth module OLED microcontrol circuit module, HDMI-to- module, power module, etc.) based on the above hardware platform, a head-mounted display driver is designed, which mainly includes head action data acquisition module. Image acquisition module and OLED display module program. 4) Design a simple augmented reality program based on the software and hardware platform of the system, mainly introduce the visual tracking matching module, graphics rendering, Virtual information presentation and interaction module software design. 5) the function verification and test of headset display for augmented reality application are carried out. The test results show that the design has reached the expected design goal.
