3-D measurement of features, including cut-outs and/or grooves
Various embodiments may include a measuring device for three-dimensionally sensing elongate cut-outs comprising: an assembly for positioning and fixing on an elongate cut-out of a body; and a 3-D measuring head connectable to the assembly to be aligned with the elongate cut-out for the respective 3-D surface measurement of the elongate cut-out.
1. A measuring device for three-dimensionally sensing elongate cut-outs, the device comprising:
an assembly for positioning and fixing on an elongate cut-out of a body defining a first longitudinal axis; and
a 3-D measuring head connected to the assembly and movable in relation to the assembly for alignment with the elongate cut-out for the respective 3-D surface measurement of the elongate cut-out;
the assembly including:
a clamping device with clamping jaws, wherein each clamping jaw is configured to detachably connect to an end surface of an end face inside the elongate cut-out;
a plate defining a second cut-out extending along a second longitudinal axis, wherein the second cut-out frames the elongate cut-out when the second longitudinal axis is aligned parallel to the first longitudinal axis;
a centering jaw operable to center the second cut-out in relation to the elongate cut-out.
2. The measuring device as claimed in claim 1 , further comprising a computer for processing and 3-D reconstruction of the 3-D data of the elongate cut-out generated by means of the 3-D measuring head;
wherein the computer forms a 3-D model of the elongate cut-out.
3. The measuring device as claimed in claim 2 , wherein the computer compares the 3-D model with a CAD model of the elongate cut-out.
4. A method for sensing elongate cut-outs, the method comprising:
positioning and fixing an assembly on an elongate cut-out of a body, the elongate cut-out defining a first longitudinal axis;
connecting and aligning a 3-D measuring head with the assembly for a 3-D surface measurement of the elongate cut-out; and
three-dimensionally scanning the surface of the elongate cut-out by guiding the 3-D measuring head along the longitudinal axis of the elongate cut-out;
wherein the assembly includes: a clamping device with clamping jaws, wherein each clamping jaw is configured to detachably connect to an end surface inside an end face of the elongate cut-out;
a plate defining a second cut-out extending along a second longitudinal axis, wherein the second cut-out frames the elongate cut-out when the second longitudinal axis is aligned parallel to the first longitudinal axis; and
a centering jaw operable to center the second cut-out in relation to the elongate cut-out.
5. The method as claimed in claim 4 , further comprising processing and reconstructing the 3-D data generated by means of the 3-D measuring head to form a 3-D model of the elongate cut-out.
6. The method as claimed in claim 5 , further comprising analyzing the 3-D measured data by comparing the 3-D model with a CAD model of the elongate cut-out.
7. The method as claimed in claim 6 , further comprising displaying models of the elongate cut-out.
8. The method as claimed in claim 4 , further comprising detaching the assembly and the 3-D measuring head from the groove and positioning and fixing the assembly on a second elongate cut-out.
