Abstract: An embodiment of this application provides a method for measuring dimensions to reduce measurement time and improve production efficiency. Specifically, the method includes: obtaining a first image and a second image of a to-be-measured workpiece, where the first image and the second image are images captured by a first camera and a second camera at different positions respectively; extracting a first corner set of the to-be-measured workpiece from the first image and a second corner set of the to-be-measured workpiece from the second image separately; rectifying position coordinates of the first corner set and position coordinates of the second corner set to obtain a position coordinate value of the first corner set and a position coordinate value of the second corner set in a same coordinate system; and obtaining dimensions of the to-be-measured workpiece based on the position coordinate value of the first corner set and the position coordinate value of the second corner set.

Abstract: Examples described herein provide a method that includes comparing features in an image (312) of a part with features of models (302) in a database and creating a list of candidate models for the part. The method further includes rendering a three-dimensional (3D) model at a pose/scale of an imaging system (310) to generate a synthetic image (308) that contains features of the part. The method further includes creating a part representation based on the features of the part, wherein the part representation depicts a defect (320) of the part. The method further includes classifying a region of the part based on a set of rules for the part to determine whether the defect (320) is within an allowable tolerance for the part.

Abstract: A quality of a formed layer of a build structure being fabricated by an additive manufacturing machine is assessed. A digital image is obtained of a portion of the formed layer of the build structure within a build layer. First region image data including data corresponding to a first region of the formed layer is separated, via a computer processor, from second region image data including data corresponding to one of or both a second region of the formed layer or a first region of the build layer outside of the formed layer based on a layer image template. A subset of image intensity data corresponding to a subset of the first region image data is analyzed, via the computer processor, to determine a characteristic value based on the analysis. An alert is sent, via the computer processor, when the characteristic value deviates from a preset range.

Abstract: Methods of inspecting fan blades (70) of a gas turbine engine (20) for abnormalities are disclosed. One method utilizes a neural network (108) to determine whether a photographic image (114) of at least one fan blade (70) depicts an abnormality of the at least one fan blade (70). Another method uses a dimensional reduction technique on one or more first photographic images (110) that depict at least one first fan blade (70) to obtain basis vectors, utilizes the basis vectors to obtain a reconstructed version of a second photographic image (114) that depicts at least one second fan blade (70), and determines whether the at least one second fan blade (70) includes an abnormality based on a difference between the second photographic image (114) and the reconstructed version of the second photographic image (114). Another method determines whether a fan blade (70) includes an abnormality based on contrast differences between adjacent areas of an image.
