Image scanning method for metallic surface and image scanning system thereof

An image scanning system for a metallic surface, comprising:

• a driver component carrying an object, a metallic surface of the object being divided into a plurality of areas along an extension direction, the driver component being further used for sequentially moving one of the plurality of areas to a detection position;
• a light source component configured to face the detection position, providing far infrared light to illuminate the detection position, wherein a light wavelength of the far infrared light is associated with the object, and a light incident angle of the far infrared light relative to a normal line of the area located at the detection position is less than or equal to 90 degrees;
• a photosensitive element configured to face the detection position, capturing a detection image of each of the areas sequentially located at the detection position, wherein a photosensitive axis of the photosensitive element is parallel to the normal line;
• and
• a processor coupled to the photosensitive element, receiving the plurality of detection images of the plurality of areas, and combining the plurality of detection images into an object image, the processor further comprising an artificial neural network system for performing a prediction procedure according to the object image to identify in the object image a regional image presenting a surface structure of the object.
