主 题:Kriging interpolation method membrane analogy twist deformation virtual soft tissue surgery simulation
摘 要:Real-time performance and accuracy are two most challenging requirements in virtual surgery *** difficulties limit the promotion of advanced models in virtual surgery,including many geometric and physical *** paper proposes a physical model of virtual soft tissue,which is a twist model based on the Kriging interpolation and membrane *** proposed model can quickly locate spatial position through Kriging interpolation method and accurately compute the force change on the soft tissue through membrane analogy *** virtual surgery simulation system is built with a PHANTOM OMNI haptic interaction device to simulate the torsion of virtual stomach and arm,and further verifies the real-time performance and simulation accuracy of the proposed *** experimental results show that the proposed soft tissue model has high speed and accuracy,realistic deformation,and reliable haptic feedback.
