Abstract
An apparatus for the industrial measurement of bores in a measurement object is provided. The apparatus includes a measurement probe which can be introduced into the bore and at which at least one distance sensor is provided with which the instantaneous distance of a reference point of the measurement probe from a wall of the bore can be determined. The measurement probe is rotatably supported at a holder which is fixed with respect to the measurement object and/or whose position relative to the measurement object is known. An evaluation device receives a number of sequentially determined distances in the course of a rotation of the measurement probe.

An apparatus for the industrial measurement of bores in a measurement object having:
- a measurement probe which can be introduced into the bore and at which at least one distance sensor is provided with which a distance of a reference point of the measurement probe from a wall of the bore can be determined,
- wherein the measurement probe is rotatably supported at a holder which is fixed with respect to the measurement object and/or whose position relative to the measurement object is known, wherein an evaluation device is designed to receive a number of sequentially determined distances in the course of a rotation of the measurement probe, and
- wherein means are provided for determining the inclination of the measurement probe relative to the holder and correction means are provided for compensating movements and error positions of the measurement probe with reference to the inclination.
A method for the industrial measurement of bores in a measurement object, by means of a measurement probe which can be introduced into the bore and at which at least one distance sensor is provided with which a distance of a reference point of the measurement probe from a wall of the bore can be determined,
- wherein said method includes the following steps:
- introducing the measurement probe into the bore;
- rotating the measurement probe in the bore, with the distances being determined repeatedly or continuously during the rotation;
- determining the inclination of the measurement probe relative to the holder;
- and
- compensating movements and error positions of the measurement probe (10) with reference to the inclination.
