Double-screen linkage display method for two-dimensional view and naked-eye three-dimensional image of three-dimensional model

Abstract

A double-screen linkage display method for a two-dimensional view and a naked-eye three-dimensional image of a three-dimensional model belongs to the technical field of free three-dimensional display, and comprises the following steps: 1, establishing a double-screen linkage display system which comprises a processor configured with Optix, Leap Motion, a three-dimensional display screen and a flat display screen; 2, setting parameter values; 3, importing a pixel-viewpoint corresponding matrix of the three-dimensional model and the two-dimensional composite image; 4, creating a virtual camera array; 5, setting a reference virtual camera; 6, displaying the two-dimensional view and the naked-eye three-dimensional image of the three-dimensional model in a linkage manner, including the steps of gesture interaction, camera parameter updating, generation and display of the two-dimensional view and the two-dimensional composite image, formation of the naked-eye three-dimensional image and the like. According to the invention, a doctor can control the viewing angle and size zooming of the plane view and the naked eye three-dimensional picture of the three-dimensional medical model in real time by using the rotation and grabbing of the palm, so that the interactive viewing of the multi-view and multi-size space information of the anatomical structure is realized, and the medical efficiency and reliability are improved.

Description

technical field [0001] The invention belongs to the field of autostereoscopic display technology, and in particular relates to a dual-screen linkage display method of a two-dimensional view of a three-dimensional model and a naked-eye three-dimensional image based on Optix and Leap Motion. Background technique [0002] Presenting an intuitive three-dimensional digital model of the patient's tissues and organs on a traditional flat-panel display is a medical image visualization method favored by doctors at present. With the increasing demand for high precision and presence in the medical field for case diagnosis, clinical observation, remote consultation, preoperative planning and intraoperative navigation, the shortcomings of this method have gradually become prominent. The two-dimensional view is not convenient to simultaneously present the multi-view spatial information of the patient's anatomical structure, resulting in poor stereoscopic depth and dynamic interactivity of...

Problems solved by technology

The two-dimensional view is inconvenient to present the multi-view spatial information of the patient's anatomical structure at the same time, resulting in poor stereoscopic depth and dynamic interactivity of the picture

Flat-panel display technology has matured, and two-dimensional views are clear, while naked-eye three-dimensional display technology is still in the exploratory stage, and optical stereoscopic images are difficult to balance in terms of clarity, depth of field, and viewing angle.
