Bone Modeling and Simulation Methods

Abstract

The invention provides a skeleton modeling and simulating method, which comprises the following steps: (1) carrying out CT scanning on a skeleton to obtain image data, and obtaining point cloud data; (2) carrying out a basal plane projection according to the outline of point cloud data and obtaining a parameter value of the point cloud data and a surface control point; (3) carrying out a body interpolation on the surface control point as a known condition, and obtaining a body parameterized model by a discrete Coons body interpolation algorithm; (4) setting a plurality of sampling points, dividing a plurality of nodes from the body parameterized model, and determining gray values of the surface control point and an inner control point through the least square method principle and quadratic optimization; (5) obtaining a skeleton model of the skeleton according to the parameter values and the grey values of the sampling points; and (6) carrying out a mesh subdivision to obtain element meshes, assembling element stiffness matrixes of the element meshes into a global stiffness matrix, obtaining the value of an unknown quantity, and finally displaying the processing result of the value of the unknown quantity.

Description

technical field [0001] The invention belongs to the field of bone model construction, and in particular relates to a more accurate bone modeling and simulation method. Background technique [0002] Simulation is to use the model to reproduce the essential process that occurs in the actual system. With the development of science and technology, the application of simulation technology is becoming more and more extensive. It is applied to electrical, mechanical, chemical, hydraulic, thermal and other systems, as well as social, economic, Biomedical, management and other systems. In terms of biomedicine, simulation has an important meaning in the history of human medicine. With biomedical simulation, doctors can improve technology through virtual patients, which reduces the pain of patients, and is low-cost, repeatable, and intuitive. Human collision injuries are the most common. Therefore, the research on bone collision injury has very important medical value. At present, ...
