<P>PROBLEM TO BE SOLVED: To provide a three-dimensional displacement measuring device capable of measuring displacement with accuracy using a three-dimensional displacement measuring unit having a simple structure. <P>SOLUTION: The three-dimensional displacement measuring device uses a three-dimensional displacement sensor 1 in which wire potentiometers 2 having pulleys wound with wires 3 therearound to detect the lengths of the wires 3 drawn on the basis of rotation angles of the pulleys rotated by drawing the wires 3 are mounted at peripheral direction angle 120° intervals at three portions on a base plate 11, and an output signal from each of the three wire potentiometers 2 of the three-dimensional displacement sensor 1. Only if the drawn lengths of the wires 3 of the three wire potentiometers 2 are measured, a three-dimensional position at a displacement measuring end 5 at a vertex of a triangular pyramid comprising the three wires 3 can be uniquely specified, and the three-dimensional position can be easily converted into a right-angle three-dimensional coordinate of XYZ using a conversion formula. <P>COPYRIGHT: (C)2013,JPO&INPIT |
