FIELD: construction.
SUBSTANCE: as per signals of three laser beacons installed along the profile of an automobile road being built, by means of two equally-spaced digital picture cameras installed on a frame of a road building machine and made in the form of photosensitive matrixes arranged in focal plane of a photographic lens, processing of a digital image picked off photosensitive matrixes is performed to determine coordinates of images of laser beacons, coordinates of three laser beacons are calculated relative to the road building machine, and then, position of the road building machine relative to the automobile road is determined.
EFFECT: automation of a process; improvement of measurement accuracy.
