โฆ Synopsis
A theory is presented for the computation of three-dimensional motion and structure from dynamic imagery, using only line correspondences. The traditional approach of corresponding microfeatures (interesting points--highlights, corners, high-curvature points, etc.) is reviewed and its shortcomings are discussed. Then, a theory is presented that describes a closed form solution to the motion and structure determination problem from line correspondences in three views. The theory is compared with previous ones that are based on nonlinear equations and iterative methods.

A great deal of dynamic computer vision literature deals with the determination of motion and structure of rigid objects by observing points on objects at two or more time instants. In some situations point correspondences may not be available but line correspondences may be, such as when edges on t
An algorithm for the estimation of rigid body motion using straight line correspondences is presented in this paper. In the case of pure translation, we present a linear algorithm using 5 line correspondences over 3 frames. In the case of general motion, it is found that the rotation and the transla
