Abstract


Augmented Reality ( AR - Augmented Reality ) , along with the rapid development of virtual reality (VR-Virtual Reality) technology and practical application needs a real-world information and the virtual world of \a real scene with virtual scene fusion technology . The main research objective is to achieve a football game video broadcast system based on augmented reality technology . According to the characteristics of the system environment , and augmented reality technology , Visual C 6.0 , DirectShow SDK , OpenCV SDK development . The system includes the core algorithm software function modules , as well as control PTZ movement hardware function module . This thesis is divided into two parts, the first part discusses the knowledge and technology involved in the development of augmented reality systems , including projective geometry , camera calibration technology and related development kits . And discusses in detail the core algorithm implementation method . Camera self-calibration algorithm has been a hot research field of computer vision , this paper circles and lines in the scene , fitting quadratic curve , and then calculate the circular points like , and finally obtain the homography matrix . The experimental results show that our algorithm in the augmented reality system is feasible , and to achieve the desired effect . The second part discusses the main function module method augmented reality system software platform , the need to enhance the reality of the real-time graphical display and interactive features , the design and implementation of an augmented reality software platform and Intro Video acquisition, the realization of the principle of the camera calibration and video processing module and the specific implementation method .
