NEAR-SURFACE OBJECT SENSING DEVICE AND SENSING METHOD |
摘要 |
Disclosed is a near-surface object sensing device, including a printed circuit board, a plurality of magnetic sensors arrayed on the printed circuit board to sense the magnetic field of an external magnetic object and generate a magnetic sensing signal, a multiplexer connected to the magnetic sensors for selecting and outputting the magnetic sensing signal, and a microprocessor connected to the multiplexer for receiving the magnetic sensing signal, wherein the microprocessor includes a sampling algorithm module for converting the magnetic sensing signal into a magnetic field distribution image, and a six-dimensional coordinate-calculating module for calculating six-dimensional coordinates of the external magnetic object. The sensing device of the invention is compact, low energy consuming and can accurately provide users with a convenient and intuitive user interface with three dimensional locations and position information in a near-surface space. |
