specific Embodiment 1

[0039] The invention provides a three-dimensional image processing method applied in zygomatic 3D printing, the method comprises the following steps:

[0040] S1, save the three-dimensional image of the zygomatic bone as an STL file, and slice the model in the STL file according to the method of uniform slice, the thickness of the slice is T1, and number the slices from bottom to top, denoted as p 1 , p 2 , , p n , where n is the number of uniform slices;

[0041] S2, get two adjacent slices p i , p i+1 The heights h1 and h2 of the middle position on the z-axis, and then obtain the areas s1 and s2 corresponding to the heights h1 and h2 in the three-dimensional image of the cheekbones. i , p i+1 Adjust the thickness of the slice; if so, execute S3, then add 1 to i, and execute S2 again; if not, add 1 to i directly, execute S2 again; when i=n-1, execute S4; where i is 1, 2, ..., n-1;

[0042] S3, for p i , p i+1 Adjust the slice thickness of the two slices, and use the ...

specific Embodiment 2

[0056] The present invention also provides a three-dimensional image processing system applied in 3D printing of cheekbones, characterized in that the system includes the following modules:

[0057] The uniform slice module is used to save the three-dimensional image of the zygomatic bone as an STL file, and slice the model in the STL file according to the method of uniform slice. The thickness of the slice is T1, and the slices are numbered from bottom to top, marked as p 1 , p 2 , , p n , where n is the number of uniform slices;

[0058] The calculation and judgment module is used to obtain two adjacent slices p i , p i+1 The heights h1 and h2 of the middle position on the z-axis, and then obtain the areas s1 and s2 corresponding to the heights h1 and h2 in the three-dimensional image of the cheekbones. i , p i+1 Adjust the thickness of the slice; if so, execute the slice thickness adjustment module, then add 1 to i, and re-execute the calculation and judgment module; i...

Abstract

The three-dimensional image processing method in the zygomatic 3D printing provided by the present invention, according to two adjacent slices p i ,p i+1 The height of the middle position on the z-axis obtains the areas s1 and s2 corresponding to the corresponding heights in the original zygomatic three-dimensional image, and judges whether to adjust the slice thickness of two adjacent slices according to the ratio of s1 and s2. If adjustment is required, re-slice two adjacent slices. By improving the slicing method, the original 3D image can be used to correct the uniform slice, avoiding the problem of excessive differences between the printed cheekbones and the 3D image model, and helping to reduce the impact of the staircase effect in 3D printing.

Description

technical field [0001] The present application relates to the technical field of 3D printing, and in particular, to a three-dimensional image processing method and system for 3D printing of cheekbones. Background technique [0002] Bone is an important organ of the human body, but due to traffic accidents, diseases and other reasons, there are a large number of bone repair operations in the world every year. The cheekbones of the face are an important component of the facial skull. Some accidents will cause damage to the cheekbones. Severely damaged bones may require replacement of the cheekbones. However, the cheekbones are not a standard part, and everyone's cheekbones are different, and customized cheekbones will bring greater financial pressure to patients. 3D printing is a new type of additive manufacturing technology. One of its important features is that it can be customized. The basic principle of 3D printing is to input the model data into the 3D printer according ...
