Summary - F.747.16 (03/2025) - Requirements for 3D machine vision-based surface defect detection service of industrial products

Recommendation ITU-T F.747.16 provides the requirements for 3D machine vision-based surface defect detection service of industrial products. Three-dimensional (3D) machine vision can obtain the complete geometric information of the real 3D scene, and the images with depth information can be used to achieve high-precision measurement, detection, positioning, reconstruction, and scene understanding. It can process various types of industrial products that cannot be processed by two-dimensional (2D) machine vision (e.g., highly reflective surfaces and low-contrast surfaces), such as electronic products and printed circuit board (PCB) surface detection, free-form surface optical mirror measurement, and measurement and detection of steel product surfaces or curved surfaces, etc.
