Problems solved by technology

Among them, the direct volume rendering algorithm is more suitable for observing the internal structure of the object. The direct volume rendering algorithm has a large amount of calculation, and the speed of browsing the reconstructed image is slow. Resolution multi-frame image reconstruction speed is still unbearable

Embodiment Construction

[0035] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0036] Such as figure 1 As shown, an image three-dimensional reconstruction method includes the following steps,

[0037] Step 1, preprocessing the original image to generate a two-dimensional image with the first resolution; the preprocessed original image has the same image size, the same resolution, higher resolution, and better image quality; the first resolution The high-resolution two-dimensional image corresponds to a sequence of first-resolution two-dimensional images, and the sequence of first-resolution two-dimensional images is stored in a first preset directory.

[0038] Step 2, resampling the first-resolution two-dimensional image to generate a second-resolution two-dimensional image lower in resolutio...

Abstract

The present invention relates to a method and system for three-dimensional image reconstruction. The method includes: preprocessing the original image to generate a two-dimensional image with the first resolution; resampling the two-dimensional image with the first resolution to generate a second-resolution image A second-resolution two-dimensional image with a low resolution of the high-resolution two-dimensional image; perform three-dimensional reconstruction on the sequence of the second-resolution two-dimensional image to form a three-dimensional reconstruction image, and cut out a plurality of block images in the three-dimensional reconstruction image Composing the region of interest of the 3D reconstruction body; calculating the coordinates, width and height of the region of interest, and calculating the start frame and end frame in the image sequence of the 3D reconstruction body; according to the calculated result, the sequence of the first resolution two-dimensional image Process one by one to obtain multiple block image sequences; perform 3D reconstruction on multiple block image sequences to obtain a preview of the region of interest. The present invention can realize fast high-resolution image preview in a low-configuration environment.

Description

technical field [0001] The present invention relates to an image processing method and system, in particular to an image three-dimensional reconstruction method and system. Background technique [0002] 3D reconstruction is a technology that constructs 3D data from preprocessed 2D image sequences and displays them on a computer screen. Common 3D reconstruction algorithms include: isosurface rendering algorithm, direct volume rendering method, maximum intensity projection method, etc. These algorithms can be applied to 2D image data with different characteristics. Among them, the direct volume rendering algorithm is more suitable for observing the internal structure of the object. The direct volume rendering algorithm has a large amount of calculation, and the speed of browsing the reconstructed image is slow. The reconstruction speed of high-resolution multi-frame images is still unbearable. Contents of the invention [0003] The technical problem to be solved by the pr...
