Abstract
A surgical navigation system comprising a positioning marker on a surgical instrument, a tracer on a bone, a binocular camera, and a computer. The tracer has a navigation tracer surface. The positioning marker comprises a navigation surface. The binocular camera is connected to the computer, and transmits acquired information of the tracer and the positioning marker to the computer. The computer and a computer readable storage medium each separately store a computer program for performing a surgical navigation method: generating three-dimensional models of a bone and the surgical instrument, and obtaining tracer registration information and calibration information of the positioning marker; receiving real-time information of the tracer and the positioning marker acquired by the binocular camera; and calculating spatial position of the bone and the surgical instrument, and fusing, in real-time, the information with the three-dimensional models to obtain dynamic images of a real-time positional relationship therebetween.
