| Abstract: | A method of skeleton retrieval based on machinery parts model is proposed.The mechanical parts extracted from the parts library are pretreated,such as chamfering,fillet and round hole,to ensure that the parts are not hollow after processing.The skeleton model is obtained by using the electric field method to extract the part model after the pretreatment.The similarity degree of the part model is calculated by using the skeleton tree matching test.The test proves that the method can quickly realize the skeleton retrieval of the part model. |
