ellipse fitting support vector machine power distribution equipments bolt detection online detection least square method random sampling principle
A novel ellipse fitting approach based on the least square method and random sampling principle is proposed to detect bolts in complex live working scenes and solve the problems of the effects of illumination,environment and noise on traditional ellipse fitting.A sorting method based on nonlinear support vector machine is proposed to classify bolts from distractors and solve the problem of alike edge of bolts and elliptical distractors.Experimental results show that,the proposed method can detect the bolts effectively and accurately from distractors.
