Abstract

The invention discloses a generation method and device for tracer identification information. The method comprises the following steps of: obtaining the three-dimensional coordinate of each near-infrared luminous point under the coordinate system of an optical positioning system; carrying out decentration on the three-dimensional coordinate, and carrying out minimum plane fitting on a point set obtained after the decentration; obtaining a projection point of the point set to a minimum plane, and according to the projection point and a normal vector of the minimum plane, determining a new three-dimensional coordinate system; according to an offset quantity which is transformed into the coordinate system of an optical positioning system by the new three-dimensional coordinate system, obtaining a rotary translation relationship; and according to the rotary translation relationship, calculating the three-dimensional coordinate of each near-infrared luminous point in the new three-dimensional coordinate system, and according to the three-dimensional coordinate, generating the tracer identification information. The tracer identification information generated by the above method can be used in different optical positioning systems, and has high compatibility.

Description

technical field [0001] The present invention relates to the technical field of tracer positioning, in particular to a method and device for generating identification information of a tracer. Background technique [0002] With the rapid development of the interdisciplinary application of robotics and medical science, research on surgical robots and surgical navigation has been more and more widely used in the medical field. At present, the surgical navigation system and surgical robot system based on the optical positioning system mainly determine the position of the tip of the surgical instrument by identifying the tracer clamped on the surgical instrument to achieve precise positioning and ensure surgical accuracy and stability. [0003] Since different surgical instruments are used in the actual operation process, the tracers on each surgical instrument are different, and different optical positioning system manufacturers define different identification files and protocols...
