Abstract:
1. A multisensor coordinate measuring device for measuring points on a surface of a workpiece, said device comprising: an x-ray computer tomography sensor system as a first sensor system for acquiring three-dimensional datasets of said workpiece, and comprising an x-ray source and at least one x-ray sensor; and a tactile and/or optical sensor system as a second sensor system, integrated within the multisensor coordinate measuring device and movable relative to the workpiece in x-, y- and/or z-direction; wherein the first sensor system and the second sensor system measure the points on the surface of the workpiece by using a common coordinate system; wherein the x-ray and tactile and/or optical sensor systems are movable relative to each other and to the workpiece; and wherein the workpiece is rotatable 360° relative to the x-ray system about a rotation axis that is perpendicular to the measuring beam direction of the x-ray computer tomography sensor system; and wherein for the measuring of the workpiece, n-sensors simultaneously struck by x-rays are assigned to the x-ray source, and wherein the x-ray source is adjusted between consecutively performed measurements relative to the workpiece at a base angle α, and wherein sensors arranged one after the other are aligned, twisted, or tilted relative to each other at an angle α/n.
