Putting webcam images onto Google Earth 3D models

Austin Abrams, a PhD candidate at Washington University in St. Louis, Missouri, US has developed a method to replace the texture of virtual buildings on Google Earth from the Archive of Many Outdoor Scenes (AMOS), a collection of live feeds from nearly 1000 webcams streaming from various sites around the world.

This application called Live3D, maps 2D webcam images onto a 3D model of a location or landmark. For example, at night it clothes the Eiffel Tower in Paris, France, with the samedarkened surface seen by a webcam. This operates by using the system's web interface, where the user outlines a region of the webcam image. Then, another window shows the Google Earth view of the scene, where the user repeats the process (this time in 3D). The program then takes whatever appears in the outlined region of the 2D image and warps it in order to fit the 3D geometry.

An incredibly interesting project, check it out in more detail by viewing the video above.
