【摘要】：随着社会的发展和国内人民生活水平的不断提高,人们个性化的摄影需求越来越强烈,作为个性化摄影领域新出现的延时摄影技术目前不仅越来越多的应用到影视节目的制作中也同样越来越多的被广大摄影爱好者所接受。为了应用延时摄影技术,首先需要配置延时摄影系统,性价比高、功能完善、稳定性高的延时摄影系统是目前国内摄影界的研究热点问题之一。电控滑道是延时摄影系统中运动控制模块必不可少的利器。有了自动滑道,会让延时作品产生3D立体感,是用别的拍摄方式所不能替代的。本文针对建立延时摄影系统的问题进行研究,并且研究了延时摄影中的渐变快门问题。课题具有重要的实用价值和广泛的应用前景。本论文主要工作如下：(1)针对延时摄影系统本身查阅了国内外相关资料,进行了课题方案论证,确定了设计延时摄影系统的方案。(2)结合具体应用需求,设计并且实现了一套包括运动控制系统和无线传输系统的功能完整的延时摄影系统。该系统运动控制部分使用了单片机来控制步进电机作为驱动,而机械部分使用了皮带加导轨的线性系统,满足了延时摄影中拍摄者需要变换拍摄交点的需求；该系统的无线信号传输部分使用了2.4G技术,使得拍摄者可以远程控制运动和拍摄系统。(3)针对延时摄影系统中需要精确控制快门的需求,提出了利用多折线逼近得出非线性渐变快门技术。由于快门的渐变时间的变化特性是非线性的,且随着太阳射入角的变化而变化,该技术可以避免在光线变化的场景下进行延时摄影时产生过度曝光或者曝光不足的问题。(4)对本文研究工作进行了总结,并对下一步工作进行了展望。
[Abstract]:With the development of society and the improvement of people's living standards, people demand more and more personalized photography strongly, time-lapse photography appears as a new personalized photography in the field of production not only more and more applied to the television program is also increasingly being accepted by the majority of photographers. In order to apply the time-lapse photography, first of all need the configuration of time-lapse photography system, high performance, perfect function, high stability of the system of time-lapse photography is one of the hot issues of domestic photography at present. The electric slide motion control module is an essential weapon system. A time-lapse photography automatic slide, 3D will let delay works have stereo feeling, is not used in other way instead of shooting. This paper established the time-lapse photography system for research, and the study of the gradual shutter problem in time-lapse photography. This paper has important practical value and wide application prospect. The main work of this thesis are as follows: (1) according to the time-lapse photography system itself access to relevant information at home and abroad, the project demonstration, to determine the design of time-lapse photography system. (2) combined with the specific application requirements, design and implement a time-lapse photography system a motion control system and wireless transmission system of complete function. The system motion control part of the use of single-chip microcomputer to control the stepper motor as a driver, and the mechanical part of the use of linear system with belt guide, to meet the needs of shooting time-lapse photography to transform shooting node demand; wireless signal transmission part of the system the use of 2.4G technology, so that the photographer can remote control movement and shooting system. (3) for the precise control of the shutter need time-lapse photography system in demand, put forward The polygonal approximation we obtain nonlinear gradient characteristics of gradient due to changes in technology. The shutter time of the shutter is nonlinear, and it changes with the sun into the corner, this can avoid excessive exposure or exposure to the problem of insufficient time-lapse photography in light of changing scenarios. (4) of the research work carried out summary and the future work is prospected.
