Abstract
An apparatus and method for measuring broken spot weld artifacts has a framework for supporting a light and a plurality of cameras for acquiring controlled images of a specimen with minimal distortion and parallax. The framework holds the specimen flat and in a reproducible position, controlling movement while imaging. The image data is received in a computer programmed with image processing software capable of isolating and measuring the artifacts. A calibration standard is used to correct for aberrations.
