Abstract
A displacement sensing system is disclosed. Two image capturing devices are settled at to opposite ends of a coordinate axis of the planar area, respectively, for capturing images of the planar area and an object placed thereon. Four pre-established LUT databases and an interactive four-matrix lookup table process are implemented to determine actual coordinates of the object on in the planar area.
