Aiming at the problem that the target is too small and illegible in modern high resolution video monitoring,to satisfy the requirement of attaining the whole information and the local information of the scene simultaneously,a method of zooming in images locally in the multi-screen playing system is proposed.Firstly,the key point of technology is analyzed,and the relationships among the panoramic image and its local parts are constructed.Then,an algorithm of locking the targets’ position by mouse is proposed and actualized.Lastly,the validity and efficiency of the method is demonstrated by the experimental result.
