Apparatus and method for scanning a surface of an article
An apparatus and a method for scanning a surface of an article such as a wooden piece transported along a travel path axis, are capable of generating two complementary color image frames representing the surface of the article in an efficient way. While the sensing field of an imaging sensor is directed transversely toward the travel path axis, a first linear-shaped light beam characterized by a first wavelength is directed toward the scanning zone to form a first reflected line onto the article surface.
