| Abstract: | A model for measuring relative depth on the fracture surface by means of computer aided instrumentation is built up according to the principle of measuring distance from stereo vision,and an improved Levine's method of detecting a pair of corresponding points is proposed. The relative depth on metal fracture surfaces,as examples,are calculated with the method presented. The results show that the method holds a good stability and high precision. |
