Resumo
Historic photographic collections are valuable documents of urban evolution through time. Many historic buildings documented in such collections may have been demolished or changed over time. Digital modeling such buildings may be challenging due to the reduced amount of information available that may be limited to a few images and/ or schematic drawings. This work presents a method to creat a 3D set of rectangles that approximates elementes of a scene (such as walls, floors, and roofs) from a single image. Using a pinhole camera model, the extraction of geometry and texture of planes parallel to an axis can be obtained after a camera calibration step that recovers intrinsic parameters of the model. Knowing the exact dimension of an object within the model allows the retrieval of its true scale. Results show that a good visualization of the scene can be created, using the proposed technique, from a single image.
