Abstract

A three-dimensioinal measurement apparatus has a detecting sensor for measuring a distance to an object having a three-dimensional shape, which detecting sensor is comprised of a non-contact type detecting sensor or a probe type detecting sensor, a drive mechanism arranged to drive the detecting sensor and having orthogonal coordinates constituted by three orthogonal X, Y and Z axes, a control section for controlling an amount of driving provided by the drive mechanism on the basis of predetermined input information and for converting a measured distance provided by the detecting sensor into distance information corresponding to a required coordinate system and outputting the distance information thus converted, and a mounting device for detachably mounting the detecting sensor to a predetermined position. The non-contact type detecting sensor and the probe type detecting sensor are used, as required, while either of them is switched to the other. The mounting device includes an intermediate adapter secured to a Z-axis spindle of the drive mechanism, a mounting shaft associated with the detecting sensor, and a detachable nut for detachably mounting the mounting shaft to the intermediate adapter.
