基于Matlab的天文望远镜实时位置仿真显示

Simulate Display of Real-time Position of Astronomical Telescope based on Matlab

本文以赤道式天文望远镜为例,利用AC4031:64入/64出通用数字I/O板来实现望远镜的位置反馈,通过Matlab/Simulink建立仿真模型和GUI界面,借助虚拟现实技术,在PC机上构造出了能被人们观察、交互、控制并可沉浸其中的三维图形虚拟空间。实现了望远镜在虚拟星空下的实时位置的仿真显示,同时也初步实现了在虚拟环境下望远镜的自动找星控制。

This paper takes the Equator Astronomical Telescope for example, compute the position feedback by using the AC4031：641/ 640 General Digital I/O Board. Build the simulation model and GUI by Maflab/Simulink, by the way of VR technology, it presents 3-D Virtual space which can be observed, interactive, and control on PC computer. Display the real-time position in the VR, and auto-find star in the Virtual World is realized.
