Abstract

A method and a system for simultaneously tracking several 6 DoF poses of a movable object and a movable camera are provided. The method the following steps: A series of images are captured by a movable camera, several environmental feature points are extracted from the images and are matched to compute several camera matrixes of the movable camera, and the 6 DoF poses of the movable camera are computed using the camera matrixes. At the same time, several feature points of the movable object are inferred from the images captured by the movable camera, the coordinates of the feature points of the movable object are corrected using the camera matrixes corresponding to the images as well as the predefined geometric and temporal constraints. Then, the 6 DoF poses of the movable object are computed using the coordinates of the corrected feature points and their corresponding camera matrixes.
