中文摘要：

设计槽式集热器（parabolic trough collector,PTC）摄影测量控制系统,可以自动完成摄影测量中的图像采集任务。根据系统需求,采用8.5m×17m的矩形导轨,作为滑块的搭载平台;采用摩擦轮驱动方式,完成相机在直线上的平移任务;采用由舵机提供动力输出的三轴云台,完成相机在三个维度上的姿态调整;系统控制软件在PC上运行,实现系统调试、站位参数设置与保存以及自动运行的功能。最终,对控制系统的各个部分进行组装,完成PTC摄影测量控制系统的样机设计与制作。系统调试表明,该控制系统满足设计要求,可以完成大型槽式太阳能集热器支架以及面形的图像采集任务。

英文摘要：

A photogrammetric control system of parabolic trough collector is designed in this paper . The photogrammetry image acquisition tasks can be automatically completed by this system . According as the front projection of PTC is 6 m × 14 m ,8 .5 m × 17 m rectangular rail is designed to carry the slider .According to the system requirements ,friction wheel drive transmission is adopted by slider to complete the movement of camera in the straight line .Servo provides power to the three-axis electric pan-tilt unit .The pan-tilt unit can complete the attitude adjustment of camera in three dimensions . PC control interface include system debug , parameter setting save and automatic operation functions .Finally ,various parts of photogrammetry control system is assembled .The design and production of photogrammetry control system for parabolic trough collector is completed .It was showed from experiments that the photogrammetry image acquisition tasks can be automatically completed by photogrammetric control system .
