Abstract: Systems and methods for infrared thermographic inspection of large-scale composite structures such as sections of an aircraft fuselage. Optical metrology is used to precisely locate the infrared images relative to a three-dimensional coordinate system of the composite structure. The optical metrology may comprise laser tracking or photogrammetry or both. In some embodiments, the optical metrology comprises laser tracking merged with photogrammetry.

In the case of thermographic porosity measurements, the infrared imaging data can be correlated with thickness data to determine the porosity of the composite structure in the inspection area.

Abstract: Optical image data is acquired by irradiating a pattern with light emitted from a light source. A threshold value is specified by internally dividing a minimum value and a maximum value of a signal amount of reference image data by a division ratio. A position corresponding to a signal amount of a threshold value is determined as an edge of a pattern of the reference image data. A position of a signal amount equal to the threshold value is determined as an edge of the pattern of the optical image data. A line width error is obtained as a difference between a first line width of the optical image data and a second line width of the reference image data. A new threshold value is specified in the case of fluctuation of a light quantity of the light source or decrease of a contrast value of the optical image data.

Abstract: This disclosure concerns image quality assessment. In particular, there is described a computer implemented method, software, and computer for assessing the quality of an image. For example but not limited to, quality of the image of a face indicates the suitability of the image for use in face recognition. The invention comprises determining (112) a similarity of features of two or more sub-images of the image (608) to a model (412) of the object which is based on multiple training images (612) of multiple different objects of that type.
