METHOD FOR MONITORING ROADWAY OF AUTOMOBILE ROADS Russian patent published in 2021 - IPC G01C7/04 

FIELD: geodetic control in the road construction industry.

SUBSTANCE: invention relates to the field of geodetic control in the road construction industry. The method for monitoring the roadway of automobile roads is characterized by the fact that they create a high-precision raster 3D model using stereo photography with digital cameras and satellite equipment. At the same time, three digital cameras are used for stereo photography, two cameras are mounted at the ends of the horizontal base, and the third is installed between them and shifted in height, stereo photography is performed in dynamics, three sets of satellite receivers are used to determine the coordinates of the photographing centers. Photogrammetric processing is carried out by constructing geometric models for each triplet of images without building a common phototriangulation network in the coordinate system specified by the coordinates of the photographing centers, 3D terrain models are built for each triplet in a single coordinate space.

EFFECT: increasing the productivity of the survey, as well as ensuring the construction of a continuous high-precision raster 3D model of the roadway.
