Abstract

The invention provides an integrated surgical navigation method and system based on augmented reality and a storage medium, and the method comprises the steps: generating a corresponding virtual 3D organ model image according to image scanning data of a patient; the virtual 3D organ model image comprises a guide graph corresponding to a preset operation scheme; obtaining a positioning tracking image through shooting of a binocular infrared camera of a terminal device; obtaining a real image of the operation area through shooting of a visible light camera of the terminal equipment; calculating a relative position matrix between a target organ and the terminal equipment according to at least three infrared reflective balls in the positioning tracking image; and according to the relative position matrix, generating and displaying a virtual reality fusion image from the real image of the operation area, the virtual 3D organ model image and the guide graph thereof. Surgical navigation assistance is achieved, repeated interruption and switching of visual attention of an operator are avoided, and the operator can conveniently, efficiently, conveniently and accurately perform an operation according to the operation scheme.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an integrated surgical navigation method, system and storage medium based on augmented reality. Background technique [0002] With the development of computer technology, the important role of computer-aided surgery simulation and aided design in surgical treatment has been widely recognized. Before the operation, the best operation plan can be formulated in the computer software, and the operation can be performed accurately according to the preoperative design during the operation, which can greatly improve the operation effect and reduce the operation risk. [0003] Surgical navigation technology is a method to help surgeons perform surgery accurately according to the virtual surgery plan, and has been widely used in neurosurgery, maxillofacial surgery, spinal surgery and other fields. The navigation system guides the surgeon during the operation by determining the r...
