Development of mono laser vision system for 3D measurement of panels with various bevel edges

In this paper, we describe the development and implementation of mono laser vision system which is used to measure large scale panels with various beveled-edges in the ship-building processes. Our laser vision system comprises of a mono camera including 4 laser-diodes and an optical band pass filter using triangulation technique. As clearly seen from this configuration, we can use only one camera to measure the edge points of large scale panels. Image processing which is an effective method to search for an edge point amongst various beveled edge shapes is presented below. Also to evaluate the below proposed algorithm, experiments were performed under real ship building environments.
