摘　　要：针对无人机(UAV)遥感航拍过程中相机载荷参数自动化控制与飞行航迹实时跟踪的问题,提出一种能自动完成相机载荷控制与航拍控制的设计方案。首先,系统根据实验要求实时获取所在地理位置信息及环境预判信息,再根据相机控制参数表进行参数编码;然后,通过通信口发送自定义协议指令集给硬件控制电路,完成相机载荷参数设置并进行拍摄,同时航迹规划软件实时记录飞行轨迹地理坐标信息。系统设计使硬件控制平台和软件数据处理相结合,实现软硬协同控制。经无人机飞行验证,与单一参数航拍控制模式相比,该系统能根据不同的拍摄环境和拍摄场景进行相机参数的自动化控制与飞行轨迹实施跟踪。Aiming at the problems of automatic control of camera load parameters and real-time tracking of the flight path in the remote sensing photography of Unmanned Aerial Vehicle（ UAV）, this paper presented a design scheme which could complete camera load control and aerial control automatically. First, the information of real-time geographic location and environment forecasting could be acquired in the system according to experimental requirements, and the parameter encoding was completed based on the table of camera control parameters; second, the custom protocol instruction set was sent to hardware control circuits through the communication port to complete the set of camera load parameters, and photography could be completed. Meanwhile, the geographic coordinate information of real-time flight path was recorded by the route planning software. The system can combine hardware control platform with software data processing, to achieve collaborative control.The UAV experiment results show that compared with the mode of single parameter aerial control, the proposed system in this paper can automatically control camera parameters and track real-time flight path according to different photography conditions and photography scenes.
