METHOD FOR TECHNICAL DIAGNOSTICS OF EARTH COVER OF RAILROADS AND MOTOR ROADS Russian patent published in 2007 - IPC G01C11/00 

FIELD: technical diagnostics of railroads and motor roads, estimation of technical condition of earth cover by remote probing methods with usage of aero-space filming in various spectral ranges.

SUBSTANCE: method includes aero-space filming of road in visible and infrared spectrum ranges, decoding on basis of image of visible range of upper structure of road and structure of earth cover, generation of map on image of visible range. Marked on the map is axis of railroad way or motorway cover, sources of possible deformations are decoded on images of visible and infrared ranges, counted from limits of sources are appropriate distances within limits of earth cover objects, generating zones of possible development of deformations of earth cover. Performed further are search and decoding of deformations of earth cover in zones of their possible development. Measured on basis of image of visible range are all deviations of real location of limits of objects from planned and if deviation values exceed predetermined threshold values, deviation zone is considered to be zone of development of deformation of earth cover.

EFFECT: increased speed due to usage of materials of one-time aero-space filming only for diagnostics and limiting area of search for deformations by zones of their possible development.
