PROBLEM TO BE SOLVED: To provide a position/pose detection device that can detect a pose (direction) with respect to a ground coordinate system without using a magnetic shield room and the like.SOLUTION: A position/pose detection device comprises: a magnetic marker 1 that is composed of a single magnetic dipole; and a plurality of vector magnetic sensors 35 that detects a magnetic field generated by the magnetic marker 1. The magnetic marker 1 is composed of an alternative current magnetism marker, and the number of the vector magnetic sensor 35 is three or more when the vector magnetic sensor 35 is a two-axis vector magnetic sensor, and the number thereof is two or more when the vector magnetic sensor 35 is a three-axis vector magnetic sensor. The magnetic marker 1 and the vector magnetic sensor 35 are electrically insulated, and the position/pose detection device is configured to use more than six pieces of magnetic field data obtained by detecting, by the vector magnetic sensor 35, the magnetic field to be generated by the magnetic marker 1 to obtain a position of the magnetic marker 1 and a direction vector thereof, in which when a single axis vector magnetic sensor is used, the number of the vector magnetic sensor 35 is more than six. In addition to the vector magnetic sensor 35, the position/pose detection device further comprises a synchronous signal magnetic sensor 3 detecting a synchronous signal of the magnetic marker 1.SELECTED DRAWING: Figure 5 |
