A virtual brain surgery simulation method based on high fusion augmented reality

Abstract

The invention discloses a virtual brain surgery simulation method based on high-fusion augmented reality, which includes: fully considering the mechanical properties of living soft tissues, integrating viscoelasticity into the deformation model of human soft tissues, and conducting biomechanical tests on real soft tissues, Determine the parameters of the soft tissue physical mechanics model, so as to obtain accurate deformation calculation results. Real-time dynamic scene information with high realism is established by rendering the background of highly simulated brain tissue area through dynamic texture mapping; mirror environment texture mapping is performed on the virtual brain tumor model to obtain a realistic texture homologous to the brain tissue environment; the combination of the two The quasi-fusion output realizes the synchronization effect on virtual and real textures, presents three-dimensional scenes through the binocular vision system, and enhances the sense of reality and immersion of the system.

Description

technical field [0001] The invention relates to the technical field of computer simulation, in particular to a virtual brain surgery simulation method based on high-fusion augmented reality. Background technique [0002] Existing virtual brain surgery simulation training systems, such as NeuroTouch, use the mesh method to calculate and simulate the deformation process of virtual brain group values. When simulating brain surgery operations such as cutting and suction, the topological structure of the virtual brain tissue grid needs to be changed, which undoubtedly increases the difficulty and complexity of deformation calculation. At the same time, the use of virtual reality to render the surgical simulation results has a large gap with the real brain surgery scene. The surgeon cannot obtain a high sense of immersion during training, and the simulation training results are inferior to the real surgery. . Contents of the invention [0003] The present invention designs and...
