摘要: 在一米红外太阳望远镜电控系统中,太阳像图像分割是进行质心检测等后续操作的基础,分割的准确性对于望远镜的跟踪控制至关重要。本文阐述了阈值分割方法的基本原理,介绍了常用的阈值选取算法,并利用迭代阈值法对太阳像进行分割研究。实验结果表明,在图像处理时间、阈值选择准确度方面,比常用的算法具有一定的优势,满足系统的要求,达到了预期的目的。

Abstract: In the electric-control system of one-meter infrared solar telescope, the sun-image segmentation is the foundation of the follow-up operation, such as centroid detection, etc. The accuracy of segmentation is very important to the tracking control of telescope. The basic principle of thresholding methods and typical threshold selecting methods are introduced, the sun-image segmentation is implemented by iteration threshold method. The experimental result shows that iteration threshold has some advantages compared with typical methods in image processing time and threshold selection accuracy, meets the requirement of control system and achieves the intended purpose.

Key words: iteration threshold, image segmentation, threshold segmentation, threshold selection
