A researcher at the University of Twente has developed software to 95 percent of the buildings can be automatically generate a 3D model. The software makes use of laser data and would work much faster and cheaper than existing methods.
The developed 3D software, built by the now-promoted Biao Xiong, uses lidar data. This point cloud consisting of an average of eight measurements per square meter for the Netherlands, are generated by measurements with lasers from helicopters or airplanes and linked to GPS data. The information is freely available via the so AHN Netherlands.
The software can recognize Xiong roof structures based on the lidar data, including details such as dormers, and so modeling parts of buildings. By combining the data can be modeled complete buildings. The level of detail would be significantly greater than with existing software.
Xiong claims further that its software is able to automatically from 95 percent of the buildings to generate a representative 3d-model. The remaining 5 percent can be manually modeled in the software. Moreover, the method is fast: the researcher claims to have a laptop in a week’s time 3D models made of the entire city of Enschede. A complete model of the Netherlands would be with more manpower in a few months to put together.
The researcher, together with four colleagues began the start-up Dipper. They want to build on the basis of software applications developed by those who are going to be used by other companies. Xiong see eg opportunities for companies like Google that are still a lot of time and money would be lost to generate current and throbbing 3d models for its Maps service card. The highly automated process that has been incorporated into its software, Google would significantly save on costs and be able to provide more timely information
