【摘要】：隨著移動技術(shù)的不斷發(fā)展和人民生活水平的不斷提高,單反相機(jī)正在人們的生活中越來越常見。社交性是照片的重要屬性之一,單反相機(jī)拍出的高質(zhì)量照片能夠更好地滿足人們的社交需求。而現(xiàn)階段的單反相機(jī)不能即時(shí)地對拍攝的照片進(jìn)行分享,已經(jīng)成為單反在社交性應(yīng)用中普及的最大瓶頸。隨著互聯(lián)網(wǎng)和各類智能設(shè)備越來越多地走進(jìn)人們的生活,WIFI無線通信技術(shù)也變得觸手可得。WIFI技術(shù)具有傳輸速率高、有效距離遠(yuǎn)、硬件成本較低和網(wǎng)絡(luò)可靠性高的特點(diǎn),基于WIFI無線通信技術(shù)的控制方案還具有組網(wǎng)簡單、便于多點(diǎn)接入的優(yōu)點(diǎn)。相對于C/S架構(gòu),B/S架構(gòu)的設(shè)計(jì)方案具有維護(hù)成本低、可擴(kuò)展性高、數(shù)據(jù)安全性好和實(shí)時(shí)性強(qiáng)的優(yōu)點(diǎn),為面向不定量用戶的服務(wù)提供了支持。研究創(chuàng)新性地提出了一種基于B/S架構(gòu)的單反相機(jī)無線控制與分享系統(tǒng)。客戶端只需要有瀏覽器和WIFI設(shè)備支持即可實(shí)現(xiàn)對相機(jī)的控制和照片分享。系統(tǒng)中主要有兩種身份的用戶:相機(jī)的控制者和照片的被分發(fā)對象。相機(jī)的控制者通過瀏覽器頁面實(shí)現(xiàn)對相機(jī)各項(xiàng)參數(shù)的設(shè)置,并可以發(fā)送相機(jī)拍攝指令、查看相機(jī)狀態(tài)、查看縮略圖和照片的灰度及RGB直方圖;被分發(fā)對象可以即時(shí)地查看到相機(jī)生成的最新照片。服務(wù)器端采用了成熟的開源軟件Apache HTTP Server,通過CGI通用網(wǎng)關(guān)接口調(diào)用外部程序以響應(yīng)來自頁面的指令和請求,結(jié)合PTP圖片傳輸技術(shù)實(shí)現(xiàn)對單反相機(jī)的控制。服務(wù)器和客戶端通過HTML報(bào)文傳輸數(shù)據(jù)和指令,拍攝所得的照片在網(wǎng)頁中顯示。研究提出的單反相機(jī)無線控制與分享系統(tǒng)具有設(shè)備支持范圍廣、控制簡便、支持多人分享以及硬件成本低的優(yōu)點(diǎn)。在專業(yè)攝影領(lǐng)域及家用攝影應(yīng)用場景中都具有廣泛的用途,具有很好的社會價(jià)值和經(jīng)濟(jì)價(jià)值。
[Abstract]:With the development of mobile technology and the improvement of people's living standards, SLR cameras are becoming more and more common in people's lives. Sociability is one of the important attributes of photos. The high-quality photos taken by SLR camera can better meet the social needs of people. At present, SLR cameras can not share the photos taken immediately, which has become the biggest bottleneck of the popularity of SLR in social applications. With more and more Internet and various intelligent devices coming into people's lives, WIFI wireless communication technology has become more and more accessible. WiFi technology has the characteristics of high transmission rate, long effective distance, low hardware cost and high network reliability, and has the characteristics of high transmission rate, long effective distance, low hardware cost and high network reliability. The control scheme based on WIFI wireless communication technology also has the advantages of simple networking and easy multi-point access. Compared with C / S architecture, the design scheme of B S architecture has the advantages of low maintenance cost, high expansibility, good data security and strong real-time performance, which provides support for service oriented to non-quantitative users. A wireless control and sharing system for SLR camera based on BFS architecture is proposed in this paper. The client only needs browser and WIFI device support to realize camera control and photo sharing. There are two kinds of users in the system: the controller of the camera and the distributed object of the photo. The controller of the camera can set the parameters of the camera through the browser page, and can send the camera shooting instructions, view the camera status, view the grayscale and RGB histogram of the thumbnail and photos; Distributed objects can instantly view the latest photos generated by the camera. The server side uses mature open source software Apache HTTP Server, to call the external program through the CGI universal gateway interface to respond to the instructions and requests from the page. Combined with the PTP picture transmission technology, the SLR camera can be controlled. The server and client transmit data and instructions through the HTML message, and the photos taken are displayed on the web page. The wireless control and sharing system of SLR camera proposed in this paper has the advantages of wide range of device support, simple control, multi-user sharing and low hardware cost. In the field of professional photography and home photography applications have a wide range of applications, with good social and economic value.
