Abstract: In a position detection system that has a plurality of transmitters/receivers placed at least three positions: processing is executed to measure distances among the plurality of transmitters/receivers, each distance being measured a plurality of times, and obtain a minimum value for each distance; processing is executed to obtain an angle between each two adjacent straight lines, each of which is one of straight lines that mutually connect the plurality of transmitters/receivers, by using minimum values, each of which is the minimum value for each distance; and if the absolute value of the difference between 180 degrees and the sum of angles, each of which is the angle between each two adjacent straight lines, inside a triangle formed by straight lines that interconnect three of the plurality of transmitters/receivers is smaller than a predetermined value, processing is executed to take the minimum values as the true values of the distances.

Abstract: A position detection system performs first through third processes to measure, using high-frequency signals, a position of a slave device in a measurement area surrounded by parent devices. The first process measures distances between the slave device and each of the master devices a plurality of times, to obtain a minimum value of each of the distances. The second process obtains a position of an intersection point of two arcs among arcs respectively having the minimum value of each of the distances as a radius from respective centers of the master devices when a number of intersection points of the two arcs within the measurement area is one. The third process regards a center of gravity of the intersection points as a true position of the slave device when the intersection points are densely arranged.

Abstract: Accelerations (Ax, Ay, Az) in directions along (X′, Y′, Z′) detected by an acceleration sensor 10 are converted, based on a correction angle γ, which is an angle between a first detection axis X′ and a first posture axis X, into accelerations (Bx By, Bz) in directions along three posture axes (X, Y, Z). A pitch angle α and a roll angle ß, which indicate a posture of a portion to which the wearable device is attached, are calculated based on the accelerations (Bx By, Bz) obtained by the conversion based on the correction angle γ.

Abstract: A position detection system according to an embodiment of the present invention includes a plurality of fixed stations 20; and a sensor unit 10 including an inertial sensor that detects movement history of a mobile body 51 and a distance sensor that detects separation distances between the mobile body 51 and the fixed stations 20. A position of the mobile body 51 is determined by detecting a first arrival position P1 obtained based on the movement history, a second arrival position P2 obtained based on the separation distances, and a relative distance L1 between the first arrival position P1 and the second arrival position P2, and by comparing a range value R1 obtained based on the movement history with the relative distance L1. The range value R1 is changed based on the movement history.
