Analysis of a sequence of images using point and line correspondences

In this paper, a feature based approach for analyzing time-varying imagery is presented. Instead of restricting the analysis to be based on points or lines, we propose to use points and lines simultaneously. A special case where four point and one line correspondences are combined for computing the structure and motion of 3D objects from a given image sequence is discussed in detail. Computer simulation results are provided to demonstrate the validity of the algorithm.
