1. A system for position and posture detection configured to determine whether to update an original position and posture information of a surgical machine stored in a surgery navigation system after moving or changing posture of the surgical machine and/or a marker module mounted on the surgical machine, the system comprising:
a sensing element configured to sense a marker of the marker module and generate a coordinate signal;
a displacement and/or angle sensing element configured to sense the marker module and generate a displacement and/or angle signal; and
a processor configured to receive the coordinate signal and the displacement and/or angle signal, wherein the processor is configured to create a transformation matrix according to the displacement and/or angle signal while the coordinate signal is different to an original coordinate signal of the marker and generate a position and posture information of the surgical machine using the transformation matrix and the coordinate signal, the position and posture information is configured to be used to determine whether to update the original position and posture information.
