Development Actuality and Application of Registration Technology in Augmented Reality

The registration in augmented reality is a process which merges virtual objects generated by computer with real world image caught by camera. This paper describes the tracker-based registration and the knowledge-based registration, and analyzes the process and current approaches of computer vision-based registration. In consideration of current research challenges, the outdoor registration technology in augmented reality is discussed in detail, and some typical applications are introduced. Then, on the basis of the development background of "UAV teleoperation and simulation system", an augmented reality method for UAV teleoperation based on Vega is illustrated. At last, it indicates that correct 3D registration in outdoor complex environment with large area and the application in teleoperation of robot or UAV is an important developing tendency in the research field of registration technology in augmented reality.
