Abstract:
The traditional computing architecture based on central processing unit ( CPU) can not meet the real-time requirement of the three-dimensional registration technique for augmented reality ( AR) . In order to solve the problem,a new idea is proposed here, in which,massively parallel processing capabilities of general-purpose graphics processing unit( GPGPU) ,with modern multi-core heterogenety are employed to accelerate and optimize the challenging techniques of the three-dimensional registration for AR. The fundamental theories,methods and experiments are explored for the key technologies including the feature extraction and matching. The results show that the potentialities of AR parallel computing of the 3D registration algorithm such as SIFT image feature extraction algorithm and random sampling can be further exploited by the methodologies of modularization and optimization. The registration algorithm can be applied to image sequences with 640×480 pixels at 15 frames /s and the real-time computing ability is improved effectively.
