Borescope inspection method and device

2:

• The method as claimed in claim 1, the method comprising:
• before calculating the 3D triangulation data, rectifying the two stereoscopic partial images on the basis of a predefined calibration.

3:

• The method as claimed in claim 1, the method comprising:
• adapting the 3D CAD reference model by the 3D triangulation data before the 2D image data are projected onto the 3D CAD reference model.

4:

• The method as claimed in claim 1,
• wherein the 2D image data are generated by superimposing the stereoscopic partial images.

5:

• The method as claimed in claim 1,
• wherein the projection point is determined beginning with a position of the stereo borescope that is determinable by a borescope guide device.

6:

• The method as claimed in claim 1,
• the method comprising:
• controlling a borescope guide device in such a way that all predefined regions of the component are captured sequentially by the stereo borescope, wherein the 3D triangulation data or the 2D image data generated in each case by way of the two stereoscopic partial images are combined with the aid of the 3D CAD reference model.

7:

• The method as claimed in claim 1,
• wherein the component to be recorded is blades of a gas turbine, wherein a rotation angle position of the blades to be recorded are taken into account when registering the 3D triangulation data to the 3D CAD reference model.

8:

• The method as claimed in claim 7,
• wherein the rotation angle position of the blades to be recorded is controlled in such a way that all blades of a turbine or compressor stage are captured.
