SPATIAL POSITION IDENTIFICATION APPARATUS AND IDENTIFICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a simply structured spatial position identification apparatus and a spatial position identification method capable of easily identifying a spatial position of an object. Ž

SOLUTION: The spatial position identification method includes the steps of generating a magnetic field G in a direction parallel to a Z-axis by a magnetic field generator 2 to be disposed in a three-dimensional coordinate system; detecting a first angle θ1formed by a first reference line L1with an X-axis by a first magnetic field detector 3 to be disposed at a first reference point A, the first reference line L1being a straight line passing the first reference point A and a point C1which is a projected generation point C of the magnetic field G onto an XY plane; detecting a second angle θ2formed by a second reference line L2with the X-axis by a second magnetic field detector 4 to be disposed at a second reference point B, the second reference line L2being a straight line passing the second reference point B and the point C1which is the projected generation point C of the magnetic field G onto the XY plane; and detecting a third angle θ3formed by a third reference line L3with a Y-axis by a third magnetic field detector 5 to be disposed at an origin O, the third reference line L3being a straight line passing the origin O and a point C2which is the projected generation point C of the magnetic field G onto a YZ plane, thus identifying the spatial position of the magnetic field generator 2.
