Abstract
System and method for position and posture detection are provided to determine whether to update an original position and posture information of a surgical machine during surgery navigation. The system includes a sensing element, a displacement and/or angle sensing element and a processor. A coordinate signal of a marker module generated by the sensing element and a displacement and/or angle signal of the marker module generated by the displacement and/or angle sensing element are received by the processor and used to create a transformation matrix. A position and posture information of the surgical machine is obtained using the transformation matrix and the coordinate signal and provided to determine whether to update the original position and posture information.
