Paper Abstract

This paper describes the development of a transverse deflection measuring system for floating dry docks. The system consists of a set of reference marks and a measurement unit. When the measurement is performed in outside for the inspection of real structures, the influence of external conditions can lead to change the position and the direction of a measurement unit. In this case, the deflection of the object cannot be measured because the effect of the camera movement is included in the measured deflection. The aim of the work is to analyze and estimate the rotation parameters of the measurement unit relative to an arbitrary axis. The result of the estimation rotation parameters can be used to compensate the error caused by the rotation of the measurement unit in the development of electro-optical system for transverse deflection measuring system for floating dry docks.
