3D City Modeling with TLS (Three-Line Scanner) Data

The TLS (Three-Line-Scanner) system is a new aerial camera system developed by STARLABO, Tokyo. Due to its flexibility in image and GPS/INS recording and the possibility of its mounting on different aerial platforms it can be used in a great variety of applications. We report about a project of producing 3D city models with TLS data. Essentially we have interfaced TLS data with CyberCity Modeler functionality and have produced two data sets over Yokohama. We will report briefly about the current status of TLS functionality (the system is still under development) and we will describe the related generation of city models. We show highresolution photo-textured models of Yokohama, including items like street lamps, roads, waterways, parking lots, bridges and trees. The combination of two modern technologies from sensing and processing opens interesting perspectives for future applications in 3D virtual environment generation.
