The Research And Realization Of The Methods Of Complicated Surface Reconstruction In Reserve Engineering

The reserve engineering technique is a Synthesize Science that includes computer assistance measure techniques, modern technological design techniques, CAD(computer assistance design) techniques, limited an analysis synthesize techniques and CAM( computer assistance manufacturing) techniques. But in this Thesis, what we want to discuss is just a brance of it-Material object reverse engineering . It refer to reconstruct the CAD modeling from the measured material object data, then use these models for analyses and manufacture of the products. And beyonding the foundation, we can carry out the error margin analysis of the products, quickly shape making, number controls Processing , borning the mold , the real imitate and so on .Surface reconstruction is one of key techniques in reverse engin eering. But because of its slowmoving that it influence the development of reverse engineering seriouly and become the bottleneck factor of whole technique progresses of its. since 90' s, along with reverse en gineering technique been appled in aviation, manufacturing, appliance and medical science realm, the theoretical research of the surface reconstruction has been launched quickly. Just because of it,this test selects a method of reconstructing the curved face of NURBS according to triangle mesh thoroughly analysising the method of surface reconstruction Contemporary . It finishs the NURBS surface reconstruction according to triangle mesh . This kind of method will makeing use both the vivid of the curved face of Bezier in triangle and the accuracy of NURBS in four directions, which can complicated surface reconstruction quickly and effiently。 in addition, it creats a...
