文档介绍：摘要
近年来,国家和社会对于高分辨率影像和大比例尺地形图需求量的越来越大,UAV 低空航测系统作为获取高分辨率遥感影像和大比例尺的地形图的一种重要方式得到了迅速的发展。组合相机作为UAV低空航测系统的传感器,也成为研究的热点。现在的组合相机的同步曝光控制通常是由电路板来控制完成的,但是这种控制方法不利于智能型组合相机控制系统的进一步研发。
本文针对这些问题,对基于程序控制的组合双相机曝光方法进行了研究。首先,对佳能公司提供的EDSDK软件开发包进行了深入的研究,并在此基础上使用VC++开发语言实现了对单个相机的控制。然后基于单相机的控制,对组合双相机的控制方法做了进一步的研究,实现了对双相机的同步控制,并且比较了单相机控制与双相机控制的不同之处。最后利用Windows多线程的程序设计原理对组合双相机同步曝光的方法进行了探讨。
实验证明,利用程序度组合相机进行控制和同步曝光是完全可以实现的。但是,针对于个组合相机对于曝光时间差的要求不同,应用程序应该使用不同的设计方法。

Abstract
As the sensor of the UAV borne low-altitude Photogrammetry system, composite cameras turn into the focus of the research. Now, the synchronous exposure of posite cameras is plished by circuit board and this method is not beneficial for the further development of the posite cameras controlling system.
To these problems, this paper studied the method posite double cameras synchronous exposure based program controlling. Firstly, this paper does deeply research to the EDSDK software development kit which offered by the pany and on this basis using VC++ development language to plish the controlling system to single camera. Secondly based the controlling of the single camera by the program, studies the controlling method posite double cameras, also plish its controlling by program, and pare the difference between single camera controlling and posite double cameras controlling. At last discuss the synchronous exposure method based on the multi-thread of the Windows system.
The experiment shows that camera control and synchronous exposure of posite camera pletely plished by the program, but due to posite style, the application should use different design method.
Key words: EDSDK, UAV borne low-altitude Photogrammetry system, composite double cameras, camera control, synchronous exposure
