Multi-functional Time-lapse Photography System Design And Implementation

Along With the continuous development of society and progress, people demand more and more strong, personalized photography as a personalized photography new time-lapse photography technology is not only more and more application in the production of film and television program is also more and more accepted by the general photography fans. To apply time-lapse photography, first of all need to configure the time-lapse photography system, high cost performance, perfect function, high stability of time-lapse photography system is one of the research hot topic at present domestic photography. Electric control way is motion control module in a time-lapse photography system indispensable tool. With automatic slide, can let the delay work to produce 3 d stereo feeling, is irreplaceable in any other way. Time-lapse photography system, this paper studies the problem of, and studied the problem of gradient shutter in time-lapse photography. Subject has important practical value and broad application prospects.This thesis mainly work as follows:(1) for time-lapse photography system itself to consult the relevant materials at home and abroad, the project scheme comparison, to determine the scheme of design time-lapse photography system.(2) combined with the specific application requirements, design and implement a set of including the function of the motion control system and wireless transmission system complete time-lapse photography system. The system motion control part USES the single chip microcomputer to control stepping motor as the drive, and the mechanical part USES the belt plus linear guide rail system, satisfy the need of time-lapse photography photographer alternating node demand; The wireless signal transmission parts of the system using the 2.4 G technology, allowing the photographer to remote control the movement and camera system.(3) for time-lapse photography system requires precise control in the demand of the shutter, put forward the use of more broken line approximation nonlinear gradient shutter technology are obtained. Due to the change of the gradient shutter time feature is nonlinear, and changes with the change of the Angle of the sun into, the technology can avoid the light changes under the scenario of time-lapse photography produced when overexposed or underexposed.(4) of this article research work is summarized, and the next step is prospected.
