Abstract: An apparatus investigates a technical device using a borescope. The apparatus has: a guide tube which is introducible through a borescope opening on the technical device to be inspected using the borescope; and a repeatedly plastically deformable carrier configured to guide a borescope head arranged at one end of the carrier. The guide tube is designed to deform the carrier during the passage of the carrier through the guide tube.

Abstract: An apparatus is used for inspecting a technical device using a borescope. The apparatus has a repeatedly plastically deformable and elongated carrier which is guidable in a deforming unit. The deforming unit has a stationary guide configured to axially guide the carrier at an outlet end and an actuator which is designed to axially guide the carrier and can be moved in at least one direction perpendicular to the gap between the guide and the actuator in order selectively to apply a bending moment to the carrier guided by the guide and the actuator. A borescope head is arranged at that end of the carrier which protrudes from the outlet end of the deforming unit.

Abstract: A borescope includes an electronic image capture unit having two image capture sensors as a borescope lens at an end of a shaft that is designed for being inserted into a borescope opening, a position and alignment of the image capture sensors in relation to one another being suitable for ascertaining three-dimension (3D) information using triangulation; and a pattern projector configured to project a pattern into a common recording region of the image capture sensors. The pattern projector includes: a fundamentally optically imaging light-guide bundle, which is made up of statistically distributed optical fibers having differing transmittances, to whose input surface a light source is coupled and whose output surface is aligned with the region captured by the image capture sensors.

Abstract: 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.

Abstract: A method for borescope inspection of a component uses a stereo borescope for recording the component. The method includes: generating two stereoscopic partial images by means of the stereo borescope; calculating 3D triangulation data from the two stereoscopic partial images; registering the 3D triangulation data to a 3D CAD reference model of the component captured by the stereo borescope, while determining a projection point; projecting 2D image data determined from the two stereoscopic partial images onto the 3D CAD reference model from the determined projection point; and determining damage by image analysis of the projected 2D image data and by ascertaining deviations of the registered 3D triangulation data vis-à-vis the 3D CAD reference model.

Abstract: 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.
