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] like 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 resolution t...

Abstract

The invention relates to a three-dimensional image reconstruction method and system. The three-dimensional image reconstruction method comprises the following steps: pre-processing an original image to generate a first resolution two-dimensional image; re-sampling the first resolution two-dimensional image to generate a second resolution two-dimensional image of which the resolution is lower than that of the first resolution two-dimensional image; performing three-dimensional reconstruction on the sequences of the second resolution two-dimensional image to form a three-dimensional reconstruction image, and cutting an ROI (Region of Interest), in which a plurality of massive images constitute a three-dimensional reconstruction body, in the three-dimensional reconstruction image; calculating the coordinates, the width and the height of the ROI, and calculating the start frame and the terminate frame in the image sequences of the three-dimensional reconstruction body; processing the sequences of the first resolution two-dimensional image one by one according to the calculation results to obtain a plurality of massive image sequences; performing three-dimensional reconstruction on the massive image sequences to preview the ROI. The three-dimensional image reconstruction method and system can realize quick high-resolution previewing of images in the 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...
