Description

PhotoSketch is a photo-centric urban 3D modeling plugin for Google SketchUp.In this video, a tutorial is presented describing how to set up a new project in PhotoSketch.We show how PhotoSketch proceeds to extract and match geometric features derived froma collection of overlapping photos of an urban scene. This is used to perform camera poserecovery in which the positions and orientations of the cameras that acquired the photos is computed.The purpose of this stage is to infer where the photographer was standing in the scene so that the resulting image can be properly projected onto the created 3D model. Modeling is enhanced by using these projected images as tracing paper upon which the user can sketch the footprint of the model use these images as visual cues for standard SketchUp extrusion and taper operations.See http://www.brainstormllc.com/ for more details.
