摘要/Abstract

摘要： 在一米红外太阳望远镜电控系统中，为了消除图像旋转对望远镜跟踪系统产生的误差，以VC++ 6.0作为开发工具，采用软件消旋的方法将CCD采集到的图像反向旋转相应的角度，同时利用双线性插值算法对图像进行重采样，从而达到实时消旋的目的。

关键词: 双线性插值, 实时处理, 图像旋转

Abstract: In the electric-control system of one-meter infrared solar telescope, in order to reduce telescope’s tracking error produced by image rotation, this paper uses VC++ 6.0 as development tool, adopts software elimination method to reversely rotate corresponding angle of image which is captured from CCD, and then uses bilinear interpolation to resample the image so as to achieve realtime eliminating image rotation.

Key words: bilinear interpolation, real-time processing, image rotation
