Abstract

A non-contact method for spatial position measuring of the objects near the smooth water surface (sea roughness code 0 points) is proposed, based on machine vision technology application. The feature of this method is the possibility of simultaneous measurement of the object height and angular orientation. The algorithm of the measurement system operation is considered. Developed installation description is given intended for the proposed method study. The measurement accuracy of height in the range of 500-1000 mm was 2-3% during the experiment. Measurement error of the angular orientation did not exceed 10%. The error sources and ways of the measurement accuracy improvement are analyzed.
