一种航空相机机载任务处理系统设计

航空相机安装在航空飞行器上,用于获取高质量的航拍图像。航空相机在机载环境下工作时,需要为像移补偿组件提供姿态和飞行参数使其工作,同时需要发出工作指令并监控航空相机返回的信息。为此提出了一套机载任务处理系统系统,采用高端工业计算机和多通道串行总线接口卡为硬件平台,设计了系统的人机交互软件,实现对机上惯导系统的飞行参数接收并接收人工输入的工作指令,使相机正常工作。对系统组成、模块的功能、总线数据收发信息的处理机制进行了描述。使用该系统控制某航空相机空中工作,所获取的图像清晰满足指标要求,这表明该系统工作正常,性能稳定。

Design of airborne mission processing system for aerial camera

Aerial camera is installed in the aircraft and it is used to obtain high-quality aerial images. When Aerial camera works in the airborne environment, the body posture and the flight parameters are needed to make image motion compen- sation module working, at the same time,it is needed o issue commands and monitor the information returned by the aerial camera. A set of airborne mission processing systems are proposed, high-end industrial computers and multi channel serial bus interface card are used as hardware platform, human-computer interaction software are designed to receive the flight parameters of the on-board inertial navigation system and instruction manual input to make the camera work properly. System composition and the function of the module and the handling mechanism of the inter bus data transceiver informa- tion are described. By using the system to control an aerial camera work in the airborne environment, the obtained ground image are clearly and meet the indicator,which show that the system works properly,the performance is stable.
