Abstract

There is provided a computer-implemented system for measuring a bulb diameter of an installed one-sided fastener in a structure. The system includes the structure and the installed one-sided fastener installed in the structure. The installed one-sided fastener has a fastener bulb with the bulb diameter. The system includes an optical imaging system. The system includes image data, including a first image of the fastener bulb, and a second image of the fastener bulb. The system includes a post image processing system, to process the image data, and to determine a bulb diameter measurement of the bulb diameter. The post image processing system includes a control system with a computer system, a trained artificial intelligence model trained to identify the installed one-sided fastener and to define edges of the installed one-sided fastener, and one or more of, an edge detection process, an ellipse fitting process, and a stereo vision process.
