Abstract
Example systems and methods are described for validating a manufacturing tolerance of a structure. A method includes receiving a digital image of a cross-section of the structure at an interface of a computing device, identifying an outer boundary of the structure from the digital image, selecting a region of the outer boundary based on changes in a first derivative or a second derivative of points of the outer boundary, identifying a geometry feature of the region of the outer boundary by comparison to stored templates of geometry features of the structure, making a comparison of the geometry feature of the region of the outer boundary to a manufacturing specification for a corresponding portion of the structure, and determining whether the structure is within a manufacturing tolerance based on the comparison of the geometry feature to the manufacturing specification.
