Abstract
In order to solve the real-time problem and the misjudgment of the traditional method
the virtual grasping recognition algorithm based on prior knowledge is introduced in an augmented reality(AR).Through analyzing a large number of experiment datas
the key datas are extracted and processed
the decision tree is constructed.A new kind of collision detection method based on data-fitting have been use to realize the recognition of grasping.The experiment results show that the algorithm has high recognition rate
well real-time
and the process of interaction is natural
which satisfies the requirement of interaction in AR system.
