Problem statement: Optical-electronic systems can be used to control the elements of large objects such as radio telescope mirrors, floating docks, bridges etc. Often, large objects have smart electromechanical systems (SEMS) to adjust the position of their elements in space. The processing unit uses reference marks to calculate the spatial position of the object’s elements and gives commands to the adjustment mechanisms to set the elements at a given position. An external force may be exerted on the measuring system and the system may rotate about an arbitrary axis. Therefore, the spatial coordinates will be calculated with an error. Purpose of research: Development of an algorithm to compensate for the random rotation of the measuring system. Results: Algorithm for finding the direction of the rotation axis and the rotation angle of the measuring system is proposed. The results of calculating the spatial coordinates on the theoretical and experimental models were compared. The developed algorithm in combination with the optical scheme allows to create measuring systems with selective invariance. Practical significance: The developed algorithm allows to increase the accuracy of measuring the spatial coordinates of the object. The proposed optical-electronic system can be used together with such systems as SEMS and automatic control systems.
