ABSTRACT

PhotoSketch: A Google SketchUp Plugin for Photo-Centric 3D Modeling

Presented by Prof. George Wolberg
Dept. of Computer Science
City College of New York

This talk presents the PhotoSketch urban 3D modeling plugin for Google SketchUp. PhotoSketch is designed to make it easy for SketchUp users to build phototextured 3D models of buildings directly from photographs. We simplify the 3D modeling workflow by leveraging the SketchUp push-pull interface with computer vision and photogrammetry techniques. The PhotoSketch plugin merges the benefits of automatic feature extraction, camera pose recovery, an intuitive sketching interface, and advanced texture mapping with occlusion detection to produce lightweight photorealistic 3D models of buildings. These models typically consist of a few hundred polygons each, which makes them well-suited for use in high-performance visualization, online gaming, and web-based applications such as Google Earth.
