Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Algorithm for Determining the Parameters of the Foundation of Buildings and Structures by Processing Georadar Images A.A. LOKTEV, D.A. LOKTEV, V.V. KOROLEV, A.A. KUZNETSOV In this paper, algorithmic and mathematical support for processing images obtained using a georadar complex is being developed. The proposed approach to image processing of images for the subsequent determination of engineering and mechanical characteristics of the soil, the presence in it of areas of flooding and soil decompression, voids, utilities, masonry, concrete elements, underground streams is based on the aggregation of methods for determining the parameters of reflected electromagnetic waves, the use of image blurring as an informative criterion determining the state of a real object, and algorithms for constructing the contour of an underground element with different properties of electrical conductivity and dielectric permittivity. The proposed solutions can be implemented in a hardware and software complex used for the construction and rapid processing of georadolocation profiles of sections located in the railway right-of-way. Keywords: electromagnetic wave, reflection coefficient, blur function, dielectric permittivity, diffraction pattern, image contour construction algorithm. DOI: 10.25791/pribor.4.2022.1331 Pp. 11-17.
