Robust estimation of 3-D line segments from satellite images for model building and change detection

This paper addresses how to automatically match and reconstruct line segments from multiple satellite images and detect changes in man-made structures by using reconstructed 3-D line segments. We propose a new approach to line reconstruction and use wireframe models to better estimate the actual 3-D geometry by using the incidence relations between reconstructed line segments. Our change detection method is widely applicable as man-made structures are the main focus of most change detection applications.
