Photogrammetry at Google Scale

Veselin Dikov

The Satellite View and Street View of Google Maps and Google Earth are created by combining satellite, aerial and ground level imagery. In this presentation I will introduce Google's “Photogrammetry” team and its mission to transform raw imagery (and some other sources) into rich consumer and analytic geo-spatial products. To meet its ambitious goal, the team develops and applies—at a massive scale— advanced photogrammetric techniques: from machine vision, bundle adjustment and calibration, to 3D reconstruction, 3D localization, and machine learning. We’ll conclude with a deep dive into the problem of co-alignment of large corpora of geographic imagery and data.
