In order to solve the problems in 3D vision measurement such as low inspection efficiency and low location precision and so on,an efficient method of ellipse detection and location is proposed.Using high-reflective characteristic of the retro-reflective targets,the Canny detector is applied to the gray level image in order to obtain a binary edge-map.Edge contours points are extracted from the edge-map and divided into several groups according to the continuity.Ellipse objects can be recognized by using major axis information of an ellipse.An ellipse fitting method based on the Heteroscedastic Errors-In-Variable(HEIV) model is applied to realize the precision locating of the ellipse objects.Experimental results show that the method has such advantages as fast speed,automation,high precision and good robustness and can be extensively applied to the vision measurement.
