Uavs Airborne Digital Camera Programmed Device Development,

As an important method of getting remote sensing images, the UAV low-altitude remote sensing system has the advantages of the low-altitude flying, agility, speediness, low cost and high resolution. Our research team has been devoted to the research of the UAV low-altitude remote sensing system for a long time, and has obtained plentiful achievements. In order to achieving the synchronous capturing control of the four cameras, this project is put forward. This paper introduces the UAV low-altitude remote sensing system at first, and then analyses the theory and the synchronization problem of the four combination cameras. This paper presents the overall architecture of the embedded controller, and then analyses the implementation approach of every function module block. Having developed the embedded controller, it adopts the method of the four cameras trigger at the same time in the software programming. After that, it measures the interval between the four cameras capturing, and then calculate the timer's initial value. To validating the synchronization, it measures the interval between the four cameras capturing in the mode of the timer delay trigger. The experiment confirms the embedded controller of the single chip processor accords with the synchronization.
