Interactive reconstruction of industrial sites using parametric models

We present a new interactive modeling technique for reconstructing 3D objects from multiple images. We specifically address the problems that arise in industrial environments during camera orientation, image segmentation and modeling. An accurate camera orientation is ensured by using coded markers and surveyed points from a total station. Interactive segmentations of edges and regions in the images are used as input for fitting parametric models to the scene. We provide an intuitive interface which allows modeling artificial objects without having extensive knowledge about 3D modeling or photogrammetry.
