Employees of the Reverse Engineering Laboratory of the State University of Management conducted research on the issues of 3D modeling.
The authors of the article “The Impact of 3D Scanning Data Processing Methods on the Quality of Final Solid 3D Models” are young scientists from the State University of Management: – Leading Researcher (Head of the Laboratory), Candidate of Technical Sciences, Associate Professor Vladimir Filatov; – Researcher, Candidate of Technical Sciences, Associate Professor Ilya Nefelov; – Specialist, Postgraduate Student Denis Yudin.
“As is known, with the help of 3D scanners, it is possible to scan the surfaces of any physical objects and make their virtual 3D models – digital twins,” says Vladimir Filatov. “This model can then be changed, and a new product can be printed or manufactured on machines, and it will take significantly less time compared to doing it from scratch. Such scanning is the first stage of reverse engineering.”
Some characteristics of a real object may prevent the correct transfer of its parameters to digital space. It may be transparent, glossy, mirror-like, have different textures or colors, have deep pockets (depressions) where light hardly penetrates or is reflected from surfaces inside it. For more accurate scanning, matting is used – the application of single-color anti-glare sprays that eliminate the properties of objects that are inconvenient for scanning.
Scientists from the State University of Management studied the deviations of the sizes of the obtained 3D model of the scanned object from its sizes measured in reality, and the influence of various sprays on this error. The studies showed how accurately the obtained 3D model coincides with the real object after scanning.
The authors reviewed methods for processing 3D scanning data, including primary processing, filling in missing surfaces, smoothing, splitting into primitives, and measurements in a virtual environment. Their impact on the quality of final solid-state electronic 3D models of scanned objects was assessed. Measurements of final length measures were performed in a virtual environment with subsequent analysis of the data obtained.
In the future, research will be aimed at studying algorithms and methods for processing the surfaces of scanned objects in order to improve the quality of digital twins of agricultural machinery.
The study can be read about in an article published in the November 2024 issue of the Standards and Quality journal.
