Embodiment Construction
[0132] The core of the present invention is to generate the first DRR image library along the out-of-plane corner direction of the first imaging plane and the second DRR image library along the out-of-plane corner direction of the second imaging plane; The X-ray image is used as the registered image, and the DRR image in the first DRR image library is used as the reference image to estimate the in-plane translation parameters, in-plane rotation parameters and out-of-plane rotation parameters of the first X-ray image; The second X-ray image of is used as the registered image, and the DRR image in the second DRR image library is used as the reference image to estimate the in-plane translation parameter, in-plane rotation angle parameter and out-of-plane rotation angle parameter of the second X-ray image respectively; according to An image registration result is obtained from the parameter estimation results of the first X-ray image and the second X-ray image.
