Abstract

The invention provides a three-dimensional virtualization processing method and system of a tomographic image, which solves the technical problem that the existing virtual reality technology has defects in the stereoscopic expression of three-dimensional virtual objects of the tomographic image. The method comprises: establishing a transparent layer covering the angle of view in the object scene of the virtual reality space, arranging a reference point matrix on the transparent layer, and the reference points in the reference point matrix are evenly distributed in a matrix; interactively controlling the objects in the object scene and The transparent layer forms the intersecting process; in the intersecting process, the local blanking of the reference lattice is formed according to the main object, and the local blanking of the secondary object is formed according to the reference lattice. Aiming at the grayscale map attribute of the anatomical object formed by the tomographic image, the three-dimensional imaging is enhanced, while maintaining the integrity of the information contained in the grayscale map. The stereoscopic perception of the anatomical object is highlighted by using the blanking position and the blanking contour, so that the two-dimensional feeling and the three-dimensional dislocation feeling formed during continuous observation of the anatomical object are weakened.

Description

technical field [0001] The present invention relates to the technical field of virtual reality technology, in particular to a method and system for three-dimensional virtualization processing of tomographic images. Background technique [0002] In the existing technology, machine learning algorithms such as deep learning can be used to obtain the basic contour features of specific medical objects such as tissues or organs in medical tomographic images, and then form basic three-dimensional data and contours of independent tissues or organs through fitting between tomographic images . In virtual reality technology (VR), the three-dimensional accuracy of scene objects in the virtual field of view is high, and the tomographic image is a grayscale image. Due to the lack of basic three-dimensional data of medical objects, virtual imaging cannot obtain a better user experience. It is mainly reflected in: among them, medical objects are often closely combined with each other, so t...
