[0018] In the following, in conjunction with the accompanying drawings, the method for segmenting the interrupted layer image of the CT film scan image of the present invention will be further explained in detail.
[0019] Figure 1 is a CT film scan image to be segmented. In the figure, there are several CT tomographic images arranged on a CT film. Therefore, before the 3D reconstruction, the tomographic image must be segmented from the film scan image one by one.
[0020] In this embodiment, the specific steps of the tomographic image segmentation method are:
[0021] 1) Determine the resolution of the reference tomographic image according to the length actually represented by the scale and the pixel coordinates of the two endpoints on the scanned image;
[0022] The CT film scan is made into a CT film scan image, and one of the tomographic images that need to be segmented is used as a reference image, and the two end points of the reference tomographic image ruler are automatica...
