Abstract:In recent years, video surveillance systems is widely used in various fields, and playing an increasingly important role in social life and production. Digital video surveillance system， as opposed to traditional analog video surveillance systems, has the biggest advantage that you can use computer graphics processing methods to develop intelligent monitoring systems.The paper first analyzes a variety of video data acquisition technology, and choose the VFW (Video For Windows)① technology to complete video data acquisition, video data editing and storing video data at last.This paper studies the VC++ based interface development technology, and designed a user-friendly interactive interface for the content of this research, and ultimately develop a system which can display real-time data captured from two cameras.

Keywords: video surveillance; video capture; VFW; digital image.
