Abstract


Augmented Reality (AR-Augmented Reality) is developed on the basis of a new technology of virtual reality (VR-Virtual Reality) technology , computer-generated three-dimensional virtual objects with the objects in the real scene seamless integration , which in turn has to complement and enhance the role of real-world information technology . The main research objective of this paper is to implement a virtual studio systems based on augmented reality technology . Virtual studio can make live video with computer - generated three-dimensional graphics in real-time integrated together . More mature commercial virtual studio system is based on an independent work platform , its expensive , small and medium-sized television unbearable . Therefore , the development of a low-cost , a practical virtual studio system has broad application prospects and practical significance . This paper first discusses , Filter related principle with knowledge -based the DirectShow video technology acquisition and control . Next, discussed in detail the Direct3D virtual graphics generation system design and the simple background video keying algorithms Finally, the overall design and implementation of virtual studio system , discussed in detail the concrete implementation of the various functional modules and done a very good anti-aliasing algorithm for the the aliasing problems appear in the video . According to the characteristics of the system and augmented reality features , we use Visual C 6.0 , the DirectX SDK , OpenCV SDK as a development tool , and to obtain the expected experimental effect .
