An Image-Based Hairline Crack Identification Method for Metal Parts

Accurate detection and measurement of hairline cracks on metal parts, typically less than 1mm wide, are important for remanufacturing. However, this task remains challenging due to the small crack size, high reflectance of the metal surface, and the lack of reliable real-size measurement methods. Th...
