RADIOGRAPHIC INSPECTION OF MECHANICAL FASTENERS

原文（中国語）

A system for automated inspection of an installed fastener includes a radiographic generator, a radiographic sensor, and a computer device. The radiographic generator is operable for directing scanning beams of electromagnetic radiation, e.g., x-rays, toward a workpiece having the installed fastener, for instance a rivet. The radiographic sensor collects a radiographic image of a workpiece inclusive of the installed fastener. The computer device processes the image via one or more trained characterization models to localize the installed fastener within the image, and identifies a presence or absence of a defect in the installed fastener. The computer device also characterizes a quality of the installed fastener based on the presence or absence of the defect, and thereafter generates an inspection report indicative of the quality of the fastener. This may include generating an annotated or color-coded image of the installed fastener.
