单反相机无线控制及分享系统的设计与实现
发布时间：2019-04-19 02:55
【摘要】：随着移动技术的不断发展和人民生活水平的不断提高,单反相机正在人们的生活中越来越常见。社交性是照片的重要属性之一,单反相机拍出的高质量照片能够更好地满足人们的社交需求。而现阶段的单反相机不能即时地对拍摄的照片进行分享,已经成为单反在社交性应用中普及的最大瓶颈。随着互联网和各类智能设备越来越多地走进人们的生活,WIFI无线通信技术也变得触手可得。WIFI技术具有传输速率高、有效距离远、硬件成本较低和网络可靠性高的特点,基于WIFI无线通信技术的控制方案还具有组网简单、便于多点接入的优点。相对于C/S架构,B/S架构的设计方案具有维护成本低、可扩展性高、数据安全性好和实时性强的优点,为面向不定量用户的服务提供了支持。研究创新性地提出了一种基于B/S架构的单反相机无线控制与分享系统。客户端只需要有浏览器和WIFI设备支持即可实现对相机的控制和照片分享。系统中主要有两种身份的用户:相机的控制者和照片的被分发对象。相机的控制者通过浏览器页面实现对相机各项参数的设置,并可以发送相机拍摄指令、查看相机状态、查看缩略图和照片的灰度及RGB直方图;被分发对象可以即时地查看到相机生成的最新照片。服务器端采用了成熟的开源软件Apache HTTP Server,通过CGI通用网关接口调用外部程序以响应来自页面的指令和请求,结合PTP图片传输技术实现对单反相机的控制。服务器和客户端通过HTML报文传输数据和指令,拍摄所得的照片在网页中显示。研究提出的单反相机无线控制与分享系统具有设备支持范围广、控制简便、支持多人分享以及硬件成本低的优点。在专业摄影领域及家用摄影应用场景中都具有广泛的用途,具有很好的社会价值和经济价值。
[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.
