Creating 3D Models of Maior Cities

摘要

Surprisingly, the idea of a web-based 3D map of Moscow came to a Russian real estate developer in a dream in early 2001. Since the quality of airborne data was insufficient to create photorealistic 3D models, terrestrial imagery would be used - and with Russia's capital city featuring more than 150,000 buildings, the project was ambitious to say the least. This article describes the team's approach to surveying such a complex city environment and the new techniques developed for producing photorealistic 3D models of buildings quickly and cost-efficiently.
