A general framework for 3D structure / motion analysis is proposed upon integration of different visual modules. Line drawings are analyzed from motion point of view, and provide an effective means for 3D reconstruction. 2D motion based and feature correspondences based approaches are efficiently integrated with the line drawing interpretations under our framework. Normal flow of line segment is employed here to characterize 2D motion and the finite difference method is used for its estimation in a simple and practical way. To implement the proposed integration model, an incremential scheme is developed ti estimate 3D structure / motion from a sequence of images. Experiments on scenes containing polyhedral objects demonstrate the feasibility of the proposed scheme, and show that the integration of different visual modules gives better 3D structure / motion estrimations.
