چکیده
This paper proposes a soft tissue grasping deformation model, where BP neural network optimized by the genetic algorithm is used to realize real-time and accurate interaction of during virtual surgery. In epidermis divided into meshes, meshes generate displacements under action tension. The relationship between tension displacement mesh determined proposed cylindrical spiral spring model. trained based on sample data point vertical tension, so as obtain force any epidermis. experiment platform built using PHANTOM OMNI haptic hand controller 3D Max software, which simulation human abdomen realized. experimental results show that model has good visual feedback, can meet requirements for in
