| Abstract: | In the field of medicine,especially in the aspect of adjusting area,3-dimensional structure of body is always needed in assistant diagnosis and assistant analysis, and it' s necessary for doctors to get accurate character points of the skull. In this article,a method on B spline curve fitting technology to medel is fully described. The question to be solved has been put forward firstly, then the flow chart is described,followed by the detailed steps to implement. |
