Problems solved by technology

However, the 3D reconstruction model generated based on the existing Marching Cubes method is a set of scattered triangular faces, and not all of the obtained triangular faces are connected. It is inconvenient to simulate the operation of the system, which makes the existing systems of this type particularly complicated, and usually needs to be implemented on a workstation
[0007] Moreover, the existing surgical simulation system generally

Embodiment Construction

[0031] Referring to FIG. 1 , it is a schematic flowchart of an embodiment of a method for establishing a three-dimensional model of an unknown human skeleton proposed by the present invention. The method includes an image data acquisition step, a model data extraction step, a model data compression step and a model data reconstruction step.

[0032] For the image acquisition step, since the 3D reconstruction of the unknown body cannot obtain volume data through direct measurement on the entity, the volume data in the original image is generally obtained by scanning the entity containing the unknown volume with a CT scanning device.

[0033]However, due to the interface problem of traditional CT, it is hindered to directly obtain the original scanning data, and it needs to rely on the tomographic film to reconstruct the model. As a result, there is a lot of data loss, large errors, and obvious distortion. Therefore, it is best to use helical CT. Spiral CT collects data continu...

Abstract

The establishing process of 3D interacting model of human unknown skeleton body includes the image data obtaining step, model data extracting step and model data re-constructing step. The model data re-constructing step includes tissue processing via mobile cube process to create triangular plane set, model recording of re-configuring and recording 3D model by means of the corresponding relation between the position of tissue in body data and the B+ tree structure in the B+ tree data structure mode, and model data re-constructing via positioning tissue and its triangular plane by means of data search mode of B+ tree structure based on the connection relation of tissues in recorded 3D model under B+ tree structure. The present invention also discloses one method of applying the said method in 3D interacting simulated body's bone operation, and the real-time interactive operation simulation provides reference for forming optimal operation plan.
