摘要： A borescope includes an electronic image capturing unit having at least one image capturing sensor with a receiving cone at a first end of a shaft, the shaft having a shaft axis and through which data and supply lines for the image capturing unit are led. The image capturing unit is arranged on a rotary head. The rotary head is secured to the first end so as to be rotatable about the shaft axis such that an axis of the receiving cone is not parallel to the shaft axis at the first end and so that the rotating head is arranged to capture a panoramic image.

摘要： A method uses a flexible endoscope to inspect one or more hard-to-reach components of a gas turbine. The flexible endoscope has at least one image capture unit, which is configured to capture visual image information and associated 3D data, and which is located at a free end of the flexible endoscope. The method includes: introducing the flexible endoscope through an inspection opening; capturing the visual image information and the associated 3D data by the at least one image capture unit; comparing the captured 3D data to a 3D model of a component to be examined, and based on the comparison, ascertaining a relative pose of the at least one image capture unit in relation to the component; and texturing the 3D model with the visual image information captured by the at least one image capture unit, in accordance with the ascertained relative pose of the image capture unit.
