A method for constructing an internal organization model and a terminal device

Abstract

The present invention is applicable to the field of virtual simulation technology, and provides a method for constructing an internal tissue model and equipment thereof, including: acquiring scan data about the internal tissue of a target object, and generating a three-dimensional model of the internal tissue based on the scan data Constructing a tissue mechanics model for each of the three-dimensional tissue models; based on the three-dimensional model, determining a plurality of model groups with adjacent relationships, and establishing a contact force function corresponding to each of the model groups; according to the three-dimensional model, The tissue mechanics models corresponding to each of the three-dimensional tissue models in the three-dimensional model and the contact force functions corresponding to all the model groups generate internal tissue models corresponding to the internal tissue. The internal organization model constructed by the invention can not only simulate and restore the internal organization in three-dimensional form, but also enable the constructed virtual model to respond to interactive operations, thereby improving the simulation degree of the model.

Description

technical field [0001] The invention belongs to the technical field of virtual simulation, and in particular relates to a method for constructing an internal organization model and a terminal device. Background technique [0002] With the development of computer technology, the application of virtual simulation technology has become more and more extensive, such as the application in the field of virtual surgery, which provides important guidance for the actual surgical process. Therefore, how to build a virtual scene that fits the actual situation, such as building a corresponding visual model for a real object in a simulation environment, has become the key to virtual simulation technology. [0003] In the process of simulating the internal tissue, the fidelity of the internal tissue model constructed in the process of responding to interactive operations, such as responding to pressing, puncturing, suturing, etc., will directly affect the accuracy of the virtual simulatio...

Problems solved by technology

[0004] In view of this, the embodiment of the present invention provides a method for building an internal organization model and a terminal device to solve the existing model building technology, which often only involves the construction of a three-dimensional model of the internal organization. When interacting with the above-mentioned three-dimensional model , the 3D model cannot respond based on interactive operations, and the reality of virtual simulation is low
