| Abstract: | A novel 3D features based automatic workpiece recognition system is proposed.The system is developed in Unigraphics environment and the automatic recognition of workpiece with high speed and high accuracy is realized.The feature vector for workpiece recognition is composed of three eigenvalues of 2nd order central moments matrix,three principal inertia moments and the volume of the workpiece.Principle of automatic recognition based on workpiece's 3D features is described,and constructions of the system are presented.Efficiency of the system is validated through the experiments of 3D workpiece recognition. |
