PURPOSE:To measure without contacting the shape of an object having a three- dimensional shape by providing a noncontacting displacement meter at the tip of an arm movable toward a material to be measured and by detecting potential vectors of the movement quantity and rotation quantity of an axial direction of from the basis point of a non-contacting displacement meter. CONSTITUTION:The direction of a vector EF between a basic point E of an optical displacement meter 22 and a measuring point F on a runner blade 4 to be measured is found by finding a rotary angle against a rotary base 12 of a rotary ring 14 with the 1st servomotor 16 and the size of vector is found by a trigonometrical survey of the noncontacting displacement meter 22. And the movement position of to the axial direction of the noncontacting displacement meter 22 is detected with the 2nd servomotor 28 and the size of vector DE is found therefrom, also the direction of vector DE from point light sources 10a, 10b, 10c is found. Further vector CD is found and a potential vector AF from a fixed coordinate origin A is found. |
