Abstract. An optoelectronic system for determining the spatial position of complex engineering structures is considered. The influence of the optoelectronic system rotation on the error in measuring displacement of reference element is analyzed. Using vector algebra and matrix analysis, a method is proposed for determining the effect of the angle of rotation of the optoelectronic system basic block and direction of the rotation axis on the coordinates of the images of reference elements located at the points of measurement of spatial coordinates of the engineering structure. Calculating the reference element image coordinates in the plane under analysis, performed in the MatLab environment for the given turning points, shows that the result of operation of such optoelectronic systems is affected not only by the angle of rotation, but also by the point at which the system rotates.
Keywords: optical-electronic deflectometer, deflection, control element, analysis field, beam deflection system, invariant system, vector analysis
