Abstract

PURPOSE:To measure three-dimensional free curved surfaces with high accuracy and high efficiency by a device wherein an analog output type displacement detector is used and an error due to a contact at the leading end of a probe which has a finite radius is compensated with correction computing for the measurement of a three-dimensional shape. CONSTITUTION:A three-dimensional shape of a body 12 to be measured which has a three-dimensional free curved surface is measured. A spherical contact 16 at the leading end of a probe 11 comes into contact with the body 12 thereby to read coordinate values. If the contact 16 has its leading end tapered into an ideal needle-like shape, a leading end position of the probe should coincide with an actual measuring position. But, the contat is of a sphere having a finit radius R and a surface of the body is inclined with a slope theta, so that a geometrical error is caused. Therefore, displacements ex-epsilonz in rectangular three axial directions in the state the contact is in contact with the surface of the body are detected, and then correction amounts Hx-Hz are computed based on thus detected displacements and the radius R. Coordinate values X-Z of the measured position is compensated thereupon, thereby to obtain correct outputs XT-ZT.
