<P>PROBLEM TO BE SOLVED: To provide a three-dimensional measuring jig that can, in addition to realizing improvement in measuring accuracy where a measuring point is on a plane or at an edge, accurately measure three-dimensional coordinates of the measuring point even when it is on a concave, and a three-dimensional measuring method using this jig. <P>SOLUTION: A three-dimensional measuring jig 1 that holds a spherical reflector R for use in obtaining three-dimensional coordinates of a measuring point P on a work W with a laser measuring device L comprises a measuring groove 4 that slidably holds the reflector R and an indication point 31 in contact with the measuring point P on the work W. The measuring groove 4 is formed in a direction of approaching or moving away from a region in which the measuring point P is present, and the indication point 31 is arranged at least on the extension of a line segment d linking the center Rp of the reflector R held by a far end part 41 away from the measuring point P of the measuring groove 4 and the center Rp of the reflector R held by a near end part 42 closer to the measuring point P of the measuring groove 4. <P>COPYRIGHT: (C)2012,JPO&INPIT |
