Augmented reality registration method and device, equipment and storage medium

Abstract

The embodiment of the invention provides an augmented reality registration method and device, equipment and a storage medium, and the method comprises the steps: obtaining real space model data of a real space model, building a real space coordinate system corresponding to the real space model, and enabling the real space model to comprise a real biological model and a real three-dimensional reference model; according to the real space model data, creating a virtual space model corresponding to the real space model, creating a virtual space coordinate system corresponding to the virtual spacemodel wherein the virtual space model comprises a virtual biological model and a virtual three-dimensional reference model; and registering the virtual biological model and the real biological model based on virtual-real registration between the virtual space coordinate system and the real space coordinate system. According to the embodiment of the invention, high-precision virtual-real automaticregistration in augmented reality is realized.

Description

technical field [0001] Embodiments of the present invention relate to computer vision technology, and in particular to an augmented reality registration method, device, device, and storage medium. Background technique [0002] Augmented reality is a technology that uses computers to process images. This technology allows the fusion of real-world images seen by users with virtual information generated by computers, thereby enhancing users' perception of the real world. In recent years, augmented reality has been widely used in the medical field, especially in surgical navigation, augmented reality can provide doctors with more intuitive navigation. However, the virtual-real registration in surgical navigation is a difficult point. Only when the virtual and real are completely overlapped can doctors be given better surgical guidance. [0003] In the prior art, a virtual-real registration method based on manual, a virtual-real registration method based on electromagnetic track...

AI Technical Summary

Problems solved by technology

[0004] However, it is found that there are at least the following problems in the prior art: the registration efficiency and registration accuracy of the manual-based virtual-real registration method are low, and it is difficult to meet the high-precision and high-efficiency requirements of medical virtual registration

The virtual-real registration method based on electromagnetic tracking is susceptible to interference from electromagnetic fields, which affects the registration accuracy

The registration accuracy of the virtual-real registration method based on optical tracking is low, and it is difficult to meet the high-precision requirements of medical virtual registration.
