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.

Abstract

A dual-screen linkage display method of a three-dimensional model two-dimensional view and naked-eye three-dimensional image belongs to the field of free stereoscopic display technology. The present invention includes: 1. Establishing a dual-screen linkage display system, including a processor configured with Optix, Leap Motion, a three-dimensional display screen, Flat display screen; 2. Set parameter values; 3. Import the pixel-viewpoint correspondence matrix of the 3D model and the 2D composite image; 4. Create a virtual camera array; 5. Set the reference virtual camera; View and naked-eye 3D images, including gesture interaction, updating camera parameters, generating and displaying 2D views and 2D composite images, forming naked-eye 3D images, etc.; the invention allows doctors to use palm rotation and grasping to control 3D medical models in real time The viewing angle and size scaling of the plane view and naked-eye stereoscopic images realize the interactive viewing of multi-view and multi-dimensional spatial information of anatomical structures, thereby improving the efficiency and reliability of medical treatment.

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...
