Abstract:

In the augmented reality registration algorithm of fiducial points , many artifical markers are added in the real scene , which makes the system veηcomplex. In order to solve this problem , a robotic visual servo system is analyzed , and an augmented reality registration algorithm based on natural feature with virtual visual servo technology is proposed. Then , by taking the geometrical characters including point and moment as the image characters ,matrices describing the interaction between the variation of image character and that of virtual relative pose , namely , the Jacobian matrices of the image , are presented , by which a 3D registration algorithm based on natural feature is achieved. As compared with the hybrid tracking and the coplane four-point registration algorithms , the proposed algorithm is of higher registration accuracy.
