Reverse Engineering Reconstruction Method of Knee Joint Based on Moving Least Squares

摘要：

This paper researches the application of CT images processing.On the basic introduction of CT image theory and features of CT images,the methods of image processing applied to the CT image have been studied.Utilizing image processing technique,CT images of knee joint will be processed to generate knee joint features contours through contours recognition and digital simulation in CT images of knee joint.Then in terms of Moving Least-Squares fitting theory,knee joint surface will be built and closed topologically through knee joint features contours by the use of Imageware RE software as to rebuilt 3D knee joint and get geometric parameter exactly.During rebuilding of knee joint model,this paper has solved some problems: orientation of contours,spline approximate,and fractal of curved surface as to guarantee accuracy of model.
