System and method for mapping navigation space to patient space in a medical procedure

A method of providing an apparatus for registration in a medical procedure, the method comprising:

• providing a rigid member;
• providing a plurality of markers configured to couple with the rigid member, providing the plurality of markers comprising providing a plurality of retro-reflective circular targets, providing the plurality of retro-reflective circular targets comprising providing each retro-reflective circular target of the plurality of retro-reflective circular targets with:
• a reflective surface portion visible by a camera of a tracking system to enable capture of image data in a tracking space by the tracking system;
• and
• a distinct identifiable portion visible by a 3D scanner of a colour 3D scanner system to enable capture of 3D scan data in a 3D scanner space by the colour 3D scanner system, the 3D scanner space distinct from the tracking space;
• and
• providing a connector mechanism configured to couple the rigid member with a reference element having a reference location,
• providing each retro-reflective circular target comprising providing each reflective surface portion with an infrared (IR) retro-reflective center for visibility by the camera of the tracking system,
• providing each retro-reflective circular target comprising providing each distinct identifiable portion with a contrasting coloured ring for enabling image data extraction from a colour point cloud collected by the colour 3D scanner system,
• providing each distinct identifiable portion with a contrasting coloured ring comprising providing each contrasting coloured ring with a contrasting colour distinct from another contrasting coloured ring, and
• providing the plurality of retro-reflective circular targets comprising providing the plurality of retro-reflective circular targets configured to facilitate stitching individual frames within the colour point cloud and improving accuracy of a 3D scan by the 3D scanner of the colour 3D scanner system.
