Problems solved by technology

[0003] However, when the patient lies on the back, the suboccipital muscles and skin will be stretched, the skin will shift, or the markers will fall off due to the weak adhesion of the markers, or the markers will be shifted artificially, which will cause the markers to shift, which will increase the positioning deviation of the surgical model. , thus affecting the preoperative registration accuracy

Abstract

The invention discloses an operation model imaging method and device based on the mixed reality technology and a storage medium, and the method comprises the steps: obtaining a lesion feature image and feature information of five sense organs of a target object; performing three-dimensional modeling according to the lesion feature image and the feature information of the five sense organs to obtain an operation model; and obtaining a solid model, and projecting the operation model to the solid model according to the feature information of the five sense organs. According to the scheme provided by the embodiment of the invention, the imaging registration of the operation model and the entity model is realized by acquiring the feature information of the five sense organs of the target object, and compared with the technical scheme in the prior art that the imaging registration of the operation model and the entity model is realized by acquiring the mark point image of the skin surface of the patient; according to the technical scheme, the problem of inaccurate projection of the operation model caused by skin displacement of the patient can be avoided, so that the pre-operation registration precision is effectively improved.

Description

Technical field [0001] The present invention relates to but is not limited to the field of image processing technology, in particular to a surgical model imaging method and apparatus based on mixed reality technology, storage medium. Background [0002] In recent years, with the rapid development of digital orthopedics and holographic digital technology, mixed reality technology (Mixed Reality, MR) has been widely used in the medical field. Mixed reality technology is a digital holographic imaging technology that allows users to observe 3D stereoscopic images in all directions without restriction by projecting 3D stereoscopic images in 3D space. In the medical field, doctors can visualize the patient's lesion in the form of three-dimensional stereoscopic images to achieve the function of guiding surgery. In related technology, the surgical model is established by collecting the patient's lesion data, and the marker point is set on the surface of the patient's head skin, the label...
