BRICS Researchers to Develop 3D Infrastructure Software

ST. PETERSBURG, Russia, Jan. 9, 2018 — Using laser scanner survey technology and photography, researchers from Russia, China and India aim to develop software for creating informative 3D-models of urban infrastructure objects.

Scientists at the Peter the Great Saint Petersburg Polytechnic University (SPbPU), in collaboration with the East China Normal University and the Indian Institute of Technology Roorkee, will develop a software to analyze 3D images of infrastructure objects and collect data using the laser scanner survey technologies and photography. The project won the the Brazil, Russia, India, China and South Africa (BRICS) Science, Technology and Innovation (STI) framework program competition for countries in those fields.

"In cooperation with our foreign colleagues, we analyze the point clouds obtained by laser scanner survey technologies and develop the software that enables to recognize the particular features of the materials, the texture of the objects and its changes,” said Vladimir Badenko, professor in the Institute of Civil Engineering at SPbPU. “Our developments can be used for monitoring and repair of the road infrastructure, as well as on the preservation of objects of cultural and historical heritage.”

The software will be useful at all stages of the object's lifecycle, including detecting defects, building information modelling and carrying out renovation.

The international team of scientists will develop the tools for processing the raw data of laser scanning survey at the first stage, transforming the information about the object into the point clouds of suitable density. For the point clouds' visualization, researchers create the image projections and combine them with photography data, significantly improving the quality of laser scanning point cloud segmentation. Using such projections for object modeling enables the display all 3D data on the plane and, accordingly, improves the quality and processing speed. In addition, it helps to adjust the required display scale of the object and to obtain the most accurate image without shadows.
