边缘检测算子在望远镜控制系统中的应用研究

Applied Research of Edge detection Operators in Telescope Control System

在一米红外太阳望远镜控制系统中,需要将CCD采集到的太阳像的中心偏移量反馈给望远镜电控系统。太阳像的中心坐标可通过提取图像的边缘信息得到,本文采取图像处理的方法提取太阳像的边缘并采用质心法对边缘进行细化,通过matlab软件的模拟分析,采用边缘检测的方法达到了预期效果。

In the control system of One-meter infrared Solar Telescope,the center-offset of solar-image captured by CCD provided to electric-controlsystem.We can get the center coordinate through solar edge extraction,in this paper,extract the edge and refine the edge by centroid method based on image processing.The matlab simulation result shows that the edge detection can within touch of design requirement.
