FIELD: measuring equipment.
SUBSTANCE: invention relates to measuring equipment and can be used in coordinate measuring apparatuses and vision systems for determining the proper coordinates and for spatial orientation relative to three surveying targets flashing at predetermined frequencies, located in a horizontal plane at the same distance from each other. The method for determining the proper coordinates using a videogrammetric system consisting of a videogrammetric apparatus and three surveying targets is characterised by the fact that the surveying targets are positioned in a horizontal plane at the same distance from each other and form a spherical coordinate system with the origin of coordinates in the geometric centre thereof, wherein the surveying targets flash at different frequencies, allowing the videogrammetric apparatus to detect and distinguish the targets, measure the angular coordinates and calculate the distance to the geometric centre formed by said surveying targets, resulting in determining the proper coordinates of the videogrammetric apparatus. The videogrammetric system for determining the proper coordinates consists of a videogrammetric apparatus and three surveying targets and is characterised by the fact that the surveying targets have different enumerations, wherein the videogrammetric apparatus identifies the surveying targets by the flashing frequency, determines the combination of enumerations of the surveying targets in the ordered sequence formed by the targets on the video image, and calculates the proper azimuth angle in the spherical coordinate system formed by the surveying targets.
EFFECT: automation of the process of determining the proper coordinates and design of the system ensuring higher speed and safety of work.
