Abstract
Provided is a method for acquiring labeled data, including acquiring a 3D-3D registration sample, wherein the 3D-3D registration sample includes a sample 3D image, a reference 3D image and 3D-3D registration data, and the 3D-3D registration data includes correspondence data between the sample 3D image and the reference 3D image; generating at least one dual-2D-image based on the sample 3D image, wherein each dual-2D-image is a combination of 2D projection images of the sample 3D image in two different directions; and generating 2D-3D registration data corresponding to each dual-2D-image based on the 3D-3D registration data, wherein each 2D-3D registration data includes correspondence data between the dual-2D-image and the reference 3D image.
