Robust and Efficient Estimation of Elasticity Parameters using the linear Finite Element Method
نویسندگان
چکیده
Realistic elasticity parameters are important for the accurate simulation of deformable objects, e. g. in medical simulations. In this paper, we present an approach for estimating elasticity parameters for isotropic elastic materials using the linear Finite Element Method. Employing the initial undeformed geometry and a measured forcedeformation relation, the method computes the elasticity parameters based on Quadratic Programming. The structure of the stiffness matrix is employed to accelerate the estimation process. Experiments suggest, that the parameter estimation approach can be used for noisy data.
