The project was the winner of the international scientific consortiums competition of the BRICS (Brazil, Russia, India, China and South Africa) countries in science, technology and innovation, part of the BRICS STI Framework Programme.
The team is developing software that will process raw data of laser scans, creating point clouds from the scan data. The researchers will create the image projections and combine them with photography data, which significantly improves the segmentation quality of the point clouds created from the laser scanning. Using those projections allows for the display of all 3D data on the monitor and improves the quality and processing speed. It also helps to adjust the required display scale of the object and to obtain the most accurate image, without shadows.
“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, a professor in the Institute of Civil Engineering at Peter the Great St. Petersburg Polytechnic University. “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 BRICS STI Framework Programme was established in 2015, and was aimed at facilitating cooperation between countries to find solutions to issues involving sustainable agriculture, food security, natural disasters, water resources and pollution treatment, new and renewable energy, energy efficiency, space research, geospatial technology, medicine and life sciences, new materials and nanomaterials, photonics, information and communication technology, ocean and polar sciences, and other areas. In 2016, the first call went out for projects involving researchers from multiple BRICS states.
Much of the data in the 3D scanning project is being processed at the Supercomputer Center at Peter the Great St. Petersburg Polytechnic University.
