I am a researcher in Virtual Earth Labs, the research arm of Microsoft Virtual Earth. Our lab focuses on solving applied research problems in modeling, image understanding, and visualization. My interests are in image-based modeling, computer vision, and visualization.

 

Prior to Microsoft, I was a member of the Stanford Graphics Lab. My doctoral dissertation was on Novel Methods for Manipulating and Combining Light Fields. Marc Levoy was my advisor.

Birds Eye Image Calibration in Virtual Earth

The fall 2007 release of Microsoft Virtual Earth 3D uses my camera calibration code for showing Birds Eye images in VE3D.

 

In the Virtual Earth Map Control SDK v6.1, the PixelToLatLong method  uses my calibration and ray-poly intersection algorithms.
