FIELD: instrumentation.SUBSTANCE: present group of inventions relates to measuring equipment, and can be used to check the railroad, in particular to determine deviation of the railroad from the design position. Method of check of spatial position of railroad means that using the receiving and analyzing systems two images of space adjacent to the railroad are obtained. Using the processing and control block the reference mark is detected on the obtained images, and coordinates of the reference elements of the reference mark are determined by preliminary measurements of the mutual spatial position of the check elements. Then displacement of the check elements relatively to the base point of the devices coordinate system in vertical, longitudinal and transverse directions are determined, angles of rotation of the reference mark around the vertical and longitudinal axes, as well as angle of system rotation relatively to the transverse axes is measured. Set of obtained values of displacement of each check element relative to the datum point of the devices coordinate system is compared with the pre-measured mutual spatial position of the mass elements. Based on the results of such comparison the displacements of the reference mark in vertical, longitudinal and transverse directions are determined. Correction of the obtained displacements is made considering the obtained angles of rotation, and railroad position is determined.EFFECT: reduced error of determination of the railroad position.2 cl, 1 dwg |
