Virtual anatomical object observation method and system based on tomographic image

Abstract

The invention provides a virtual anatomical object observation method and system based on a tomographic image, and solves the technical problem that stereoscopic vision expression of a virtual anatomical object of the tomographic image has defects. The method comprises the steps of: establishing a transparent image layer covering a field angle in an object scene, enabling the axis of the transparent image layer to intersect with or is perpendicular to the focal plane of equipment presenting a virtual reality space, and arranging a reference dot matrix on the transparent image layer; interactively controlling an object in the object scene to form an intersection process with the transparent image layer; in the intersection process, forming reference dot matrix local blanking according to the main object, and forming secondary object local blanking according to the reference dot matrix, comprising: reference points of the reference dot matrix are set to be transparent blanking in an intersection surface outline formed by the main object; and setting the passage portion to be transparent blanking within an intersecting surface profile formed by the secondary object. The stereoscopic visual perception of the anatomical object is highlighted, so that the two-dimensional perception and the three-dimensional dislocation perception formed when the grayscale map of the anatomical objectis 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 observing virtual anatomical objects based on 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 th...
