Three-dimensional virtualization processing method and system for tomographic image

Abstract

The invention provides a three-dimensional virtualization processing method and system for a tomographic image, solving the technical problem that defects exist in three-dimensional virtual object stereoscopic vision expression of an existing virtual reality technology for the tomographic image. The three-dimensional virtualization processing method comprises the steps that a transparent image layer covering a field angle is established in an object scene of a virtual reality space, and reference dot matrixes are arranged on the transparent image layer, and reference points in the reference dot matrixes are evenly distributed in a matrix mode; an object in the object scene is interactively controlled to form an intersection process with the transparent image layer; and in the intersectionprocess, local blanking of the reference dot matrix is formed according to the main object, and local blanking of the secondary object is formed according to the reference dot matrix. For the three-dimensional virtualization processing method, enhancement processing of three-dimensional imaging is performed on gray-scale map attributes of an anatomical object formed by a tomographic image, and integrity of information contained in a gray-scale map is maintained at the same time; and the stereoscopic visual perception of the anatomical object is highlighted by utilizing the blanking position and the blanking outline, so that the two-dimensional perception and the three-dimensional dislocation perception formed when the anatomical object is continuously observed 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...
