Document Type and Number:

WIPO Patent Application WO/2020/007111

Kind Code:

A1

Abstract:

Disclosed in the present application are a registration method for visual navigation of a dental implant surgery, and an electronic device. The method comprises: obtaining a target tooth registration three-dimensional model, a target tooth registration solid model, and a second target tooth model; obtaining a position and attitude matrix of the target tooth registration three-dimensional model in a virtual coordinate system according to coordinates of at least three points on a base three-dimensional model obtained after the registration of the target tooth registration three-dimensional model in the virtual coordinate system; and installing the target tooth registration solid model on a registration standard board, obtaining a position and attitude matrix of the target tooth registration solid model in a visual coordinate system according to three optical markers and the points on the target tooth registration solid model corresponding to the at least three points, and obtaining a correspondence between the virtual coordinate system and the visual coordinate system according to the two position and attitude matrices. The present registration method and electronic device for visual navigation of dental implant surgery improve registration accuracy between the two coordinate systems.
