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
