【摘要】：現(xiàn)在數(shù)字游戲?qū)嵕盎捎谄淠芙o人帶來逼真、刺激的感受和前所未有的親身體驗,已經(jīng)成為了炙手可熱的游戲項目之一,得到了廣泛的應(yīng)用。本文聚焦于數(shù)字實景游戲?qū)崿F(xiàn)的硬件平臺,首先介紹了數(shù)字實景游戲硬件平臺的總體方案和基于硬件平臺的軟件設(shè)計中所用到的關(guān)鍵程序子模塊,接著詳細論述了無線視頻的傳輸過程和數(shù)據(jù)采集過程。本文主要完成的工作是:1.硬件結(jié)構(gòu)的搭建。在硬件的搭建結(jié)構(gòu)上采用了WRTnode無線路由板和以ATmega128為核心的自制電路板兩塊板子組裝而成。WRTnode無線路由板主要完成無線視頻數(shù)據(jù)的處理和傳輸,以ATmega128為核心的自制電路板主要完成狀態(tài)數(shù)據(jù)的采集以及和手機上位機APP的通信。這樣做有效的把視頻數(shù)據(jù)的處理和指令處理分開,使得各類數(shù)據(jù)能夠獨立快速處理,便于有效合理配置系統(tǒng)資源。2.無線局域網(wǎng)子系統(tǒng)的搭建。為了提高系統(tǒng)性能,使視頻傳輸實時性得到保障,本文使用了WRTnode無線路由板來搭建無線局域網(wǎng),它內(nèi)置無線路由,采用OpenWrt環(huán)境,集成了攝像頭的底層驅(qū)動,使系統(tǒng)之上的應(yīng)用程序開發(fā)更加方便。同時編寫了攝像頭圖像抓取和處理的應(yīng)用軟件包,該軟件包規(guī)定了視頻的編解碼算法、幀率、格式等基本視頻信息。3.智能手機上位機APP與以ATmega128為核心的自制電路板之間的指令通信。這部分包含了通信協(xié)議的制定,指令數(shù)據(jù)的編碼與解碼過程,最終實現(xiàn)了上位機APP和自制電路板端口之間的控制。
[Abstract]:Now digital game reality has become one of the hottest game projects and has been widely used because it can bring lifelike, exciting feeling and unprecedented personal experience. This paper focuses on the hardware platform of the digital realtime game. Firstly, it introduces the overall scheme of the hardware platform and the key program submodules used in the software design based on the hardware platform. Then the transmission process and data acquisition process of wireless video are discussed in detail. The main work accomplished in this paper is 1: 1. The construction of hardware structure. WRTnode wireless routing board and ATmega128 self-made circuit board are used to build the hardware structure. WRTnode wireless routing board mainly completes the processing and transmission of wireless video data. ATmega128 as the core of the self-made circuit board mainly completes the status data acquisition and communication with the mobile phone PC app. In this way, video data processing and instruction processing can be separated effectively, and all kinds of data can be processed independently and quickly, which is convenient to allocate system resources effectively and reasonably. The construction of WLAN subsystem. In order to improve system performance and ensure real-time video transmission, WRTnode wireless routing board is used to build WLAN, which uses OpenWrt environment and integrates the bottom driver of camera. Make the application development on the system more convenient. At the same time, an application software package for camera image capture and processing is developed. The software package provides the basic video information. 3. The video encoding and decoding algorithm, frame rate, format and so on. Command communication between smart phone PC app and self-made circuit board based on ATmega128. This part includes the establishment of communication protocol, the encoding and decoding of instruction data, and the control between the PC app and the self-made circuit board port.
