PhotoSketch is a photo-centric urban 3D modeling plugin for Google SketchUp. In this video, we present an introduction to the PhotoSketch modeling workflow. We review camera calibration, camera pose recovery (including feature extraction, feature matching, and floor alignment), sketching, extrusion, and taper operations. Models can be uploaded to Google Earth. Several examples of uploaded phototextured models are given. Seehttp://www.brainstormllc.com/ for more details.
