Abstract:
Disclosed is an image registration and an augmented reality system and an augmented reality method thereof which is suitable for solving the problem of spatial localization of the temporomandibular joint (TMJ) in arthroscopic surgery. The system comprises a three-dimensional scanning model building device, a stereoscopic image photographing device, a projection device and an arithmetic unit. The three-dimensional scanning model was constructed by preoperative or intraoperative imaging of the patient, and the surface three-dimensional model constructed by the stereoscopic image photographing device was spatially aligned to remove the surface (skin layer) of the three-dimensional image to display the TMJ image. Through the calibration of the stereoscopic image photographing device and the projection device, accurate, three-dimensional TMJ image location information is projected onto the patient's body to achieve the purpose.

Claim (Index 10):
A method of image registration and augmented reality, comprising:\n A. Scanning a cranium of a body by utilizing a three-dimensional scanning model building device to generate a plurality of anatomic images, and then building a three-dimensional scanning model according to the plurality of anatomic images; B. Capturing a plurality of skin surface images of the cranium and ears of the body by utilizing a stereoscopic image photographing device, and then building a surface three-dimensional model according to the plurality of skin surface images; C. Correcting and aligning the three-dimensional scanning model and the surface three-dimensional model according to a plurality of structural reference points on surfaces of a temporal portion and the ears of the body through an arithmetic unit, and then combining the aligned three-dimensional scanning model with the aligned surface three-dimensional model to visualize a three-dimensional image; D. Projecting the three-dimensional image onto a corresponding skin surface of the body; and E. Removing the surface three-dimensional model of the three-dimensional image, and displaying at least an internal tissue image of the body of the three-dimensional image.
