| description | The invention relates to a spheroid bone model sphere center positioning method and system based on an optical navigation system. The method comprises the steps that a transformation matrix of a first positioning tool under an optical positioning camera coordinate system is acquired; the tip of the second positioning tool slides at a preset point position on the surface of the spheroid bone model, and real-time three-dimensional coordinates of the preset point position on the surface of the spheroid bone model under the optical positioning camera coordinate system are collected; according to the transformation matrix and the real-time three-dimensional coordinate of the preset point location on the surface of the spheroid bone model in the optical positioning camera coordinate system, obtaining the three-dimensional coordinate of the preset point location on the surface of the spheroid bone model in the first positioning tool coordinate system; constructing a point location coordinate set according to the thr |
