Abstract: At least one carrier is applied onto an object, the at least one carrier including two optically different markings that are spatially separated on the carrier. At least one camera images the object from different spatial directions and a computer executes a program to evaluate images acquired by the at least one camera. Three-dimensional surface measurement of the object is provided by positioning the object onto a central region of a base, applying the carrier onto the object, and acquiring a plurality of images of the object from the different spatial directions.

Abstract: An apparatus and a method for automatic inspection of through-holes of a component is provided. The proposed apparatus includes an imaging module, an image processing module and an analysis module. The imaging module generates a thermographic image of the component by passing a medium through the through-holes and capturing infra-red radiation emitted from the component while the medium is flowing through the through-holes. The image processing module fits the thermographic image on a digital image obtained from geometrical data of the component. The image processing module is further masks the fitted thermographic image using a digital image mask to extract regions corresponding to through-holes in the thermographic image. The digital image mask is computed based on a determination of positions of through-holes on the digital image. The analysis module evaluates the masked thermographic image to determine an irregularity or blockage in one or more of the through-holes.

Abstract: A device for checking the passability of a through-hole of a component includes a front section and an inflatable balloon. The front section is configured so that it can be pressed into or onto the through-hole. The inflatable balloon is fluidically connected to the front section. In one embodiment, a middle section is provided, which is formed as a tube, wherein the inflatable balloon, is fluidically connected to the front section via the middle section.

Abstract: A testing system for examining the coating and open cooling-air holes of turbine blades includes a positioning device for an infrared camera with two degrees of freedom, a rotating-pivoting device for positioning the turbine blade, and a rotatable air duct arranged on the rotating-pivoting device. The rotatable air duct is configured for introducing into the turbine blade air at a temperature higher or lower in comparison with the turbine blade.

Abstract: By combined flow of gas in the hollow component with outlet holes in a body of the component and thermographic measurement of heated air exiting the component through the outlet holes, the component can be examined. The component is examined in an apparatus in respect of its cooling air consumption and selected desired cross sections of cooling-air openings. A process is to supply gas to a gas calming chamber, convey the calmed gas into the component, and thermographically measure the gas exiting the outlet holes.

Abstract: Method for object marking using a three-dimensional surface inspection system using two-dimensional recordings and method by simple recording of two-dimensional images of a component and comparing the images with a known three-dimensional model for enabling the three-dimensional real structure of a component to be captured using best fit. Photographing measuring points in a measuring point pattern and orienting the component with reference to markers at the points enables orienting the two-dimensional images with the three-dimensional model.

Abstract: The three-dimensional real structure of a component can be captured by means of best fit by simply recording two-dimensional images and comparing a known three-dimensional model. A component is placed on a measurement stage having reference marks and is photographed several times in two-dimensions. The photo recordings are compared with a three-dimensional model of the component. A three-dimensional model is produced using best fit of the two-dimensional recordings and the stored model.
