【摘要】：近年來,在虛擬現實技術基礎上發(fā)展而來的增強現實技術已經成為計算機圖形圖像處理領域的一個研究熱點,而隨著移動計算技術的發(fā)展誕生了一門新興的技術——移動增強現實,即基于移動終端的增強現實技術。目前,以智能手機為代表的移動終端也獲得了迅速的發(fā)展,其具有的計算能力和圖形處理能力能與桌面計算機相媲美,加之其獨特的便攜性等優(yōu)勢,基于移動終端的增強現實系統(tǒng)在不斷發(fā)展。同時,由于移動終端自身硬件結構的局限性,在用戶使用過程中的問題也逐漸凸顯出來,一方面,諸如手機、平板電腦等移動終端產品的顯示屏幕無法呈現增強現實應用中所需的沉浸感;另一方面,雖然手機、平板電腦等移動終端產品中配備了陀螺儀、加速度計、攝像頭等傳感設備,但是用戶在使用的過程中需要手持,體驗效果欠佳。此外,新型的交互技術,如頭動跟蹤技術要求傳感器獲取頭部動作數據,這在手機、平板電腦等移動終端產品中無法實現。針對以上問題,本文設計了一款與智能手機相結合的面向增強現實應用的頭戴顯示器。該頭戴顯示器不僅能夠實現增強現實應用所需的沉浸感,而且能夠將增強現實應用所需采集的頭部動作數據以及外界圖像信息發(fā)送給上位機。本文的內容包括以下幾個方面:1)對頭戴顯示器進行需求分析,在此基礎上提出了系統(tǒng)整體設計方案,完成了系統(tǒng)軟硬件平臺的方案設計,并對硬件平臺的核心器件進行了對比選型,對軟件平臺的功能和結構進行了介紹。2)在總體方案設計的基礎上,完成了頭戴顯示器硬件平臺的具體設計。主要包括采集模塊、攝像頭模塊、藍牙模塊、OLED微控制電路模塊、HDMI轉VGA模塊、電源模塊等。3)基于以上硬件平臺,設計了頭戴顯示器驅動程序,主要包括頭部動作數據采集模塊、圖像采集模塊和OLED顯示模塊程序。4)在系統(tǒng)軟硬件平臺的基礎上設計了簡單的增強現實程序,主要介紹了視覺跟蹤匹配模塊、圖形渲染、虛擬信息呈現與交互模塊軟件設計。5)對面向增強現實應用的頭戴顯示器進行了功能驗證和測試,測試結果表明本次設計達到了預期的設計目標。
[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.
