Abstract

The invention discloses an augmented reality method for dental surgery and a device thereof. The method includes: acquiring a position and a posture of a first visual marker and a second visual marker; obtaining a transformation matrix between a second coordinate system and a first coordinate system according to the position and posture of the first visual marker and the second visual marker; obtaining an coordinate set of an object to-be-located at the first coordinate system according to the coordinate set of the object to-be-located in a virtual coordinate system, a transformation matrix between the virtual coordinate system and the second coordinate system, and the transformation matrix between the second coordinate system and the first coordinate system; obtaining a pixel coordinate set of the object to-be-located according to the coordinate set of the object to-be-located in the first coordinate system and a projection matrix of the first coordinate system to the pixel coordinatesystem, and displaying the object to-be-located on a two-dimensional image according to the pixel coordinate set. The augmented reality method and the device for dental surgery provided by the embodiments of the present invention improve the positioning accuracy of the object to-be-located.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of medical robots, and in particular to an augmented reality method and device for dental surgery. Background technique [0002] In recent years, with the clinical promotion of oral implant technology and the improvement of people's requirements for oral health, more and more patients choose to have implant restoration treatment for missing teeth. [0003] Oral implant surgery requires precise operations in a narrow space. Due to the narrow operating space of the oral cavity, it is difficult to directly observe the position of the implant for operation. The positioning of the implant position depends on the experience of the doctor, resulting in the positioning of the implant. If it is not accurate enough, it will easily cause the failure of implant surgery. [0004] Therefore, how to propose an augmented reality method for dental surgery, which can improve the positioning accuracy of ...
