To develop a magnetic type azimuth/position measurement device capable of generating a three-dimensional magnetic field in space sufficient for a whole body of a patient and measuring an azimuth and a position of a motion device with an embedded magnetic field sensor, in the sufficiently large three-dimensional space, with the spatial resolution of 20 µm or smaller, the azimuth resolution of 0.2° or smaller, a positional error of 100 µm or smaller, and an azimuth error of 1° or smaller. There is provided a magnetic type azimuth/position measurement device including a three-dimensional magnetic field generating device that generates a uniform magnetic field and an inclined magnetic field independently along an X axis, a Y axis, and a Z axis in given three-dimensional space, a uniaxial magnetic field sensor that measures a strength of the magnetic field, and an arithmetic operation apparatus that calculates a position and an azimuth of the magnetic field sensor in the three-dimensional space. |
