NUROP – Modeling from Photographs

In many areas, we need a virtual representation of our real world surroundings. However, reconstructing a model of an actual scene is usually a tedious process. In this report, we explore a novel workflow for architectural model reconstruction from photographs. We keep the interaction with our system at a 2D level to reduce the complexity of our user interaction using a mesh-grid that the user interactively builds from a supplied photograph. At every step, the user can adjust the grid appropriately to ensure the quality of the resulting model. The interaction is kept in 2D by employing the constraint that the shifting of the gird lines is parallel to one of the 3 orthogonal axis of the structure. To facilitate the building of the mesh-grid, we make use of a tile finding algorithm to find the period of a section of the image. We demonstrate our proposed workflow with a prototype implementation.
