Different quality level processes and products for ground-based 3D city and road modeling

Abstract

This paper proposes ideas and some solutions for providing different quality level processes and products of a ground-based Mobile Mapping Data Collection System (MMDCS) for 3D city and road modelling. The primary products are image-based databases with different georeferencing qualities. Then cooperative applications of terrestrial and aerial images for higher level processes such as road-marks extraction and building reconstruction are discussed. We will also show that an image database is of great potential to improve quality of positioning in autonomous navigation applications.
