Abstract: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 threeaxis electric pantilt unit. The pantilt 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.
