Abstract
2-D vision approach used to measure dimensions of complex cross-section of an object is presented in the paper. Considering the complexity of profile in cross section, some methods for edge detection and geometric elements recognition are studied. The means that can acquire a fine boundary image is adopted. A special approach for recognizing all geometric elements in image is presented. The recognition is processed by matching elements in image with corresponding elements in a standard graph. The standard graph is drawn according to the machine drawing. The measurement for total parameters is accomplished at the same time. The measure precision is ± 0.05mm.
