基于PXA270的移动天文观测系统设计

Design of Mobile Astronomical Observation System Based on PXA270

针对目前天文观测系统的局限和不足,在基于Intel PXA270和Linux环境下设计了一套新的移动天文观测系统。采用一种特殊的求天体视位置的算法,实现了天体的高精度定位。用户可通过简单的点击操作使天文望远镜自动转向欲观测的星球,应用数字化视频采集技术将观测的对象显示在屏幕上,并对图像进行实时处理,增强了观测效果。最后给出了实测数据,通过数据可以判断该系统与其他系统相比具有精度高,误差小,观测效果好等优点。

A set of new mobile astronomical observation system based on the Intel PXA270 and Linux operation system is designed, aiming at the limitation and shortcoming of present astronomical observation System. Adopting arithmetic about calculating view position of celestial bodies,and realizing the excellent precision position of celestial bodies. Subscriberes can enable astronomical telescope turning around celestial bodies automatically which people can observate by dotting simply. It can display observation object on the screen by applying digital video gather technology, and manipulate an image, enhancing observation effect. Finally, the article gives the measured data, through the data, the system that has the advantages such as high precision, small errorswith, etc. compared with other systems.
