Abrégé

The inspected object (9) is illuminated by different light sources (5, 6, 7 and 8) with a common intensity. The light sources {5, 6, 7 and 8) comprise LED emitters (50, 60, 70 and 80) of different wavelengths: Red, Green, Blue and Near-Infrared Radiation (NIR), and are arranged surrounding the optical axis (4) of the one shot camera. The object (9) may either be in a static position or in movement following a predetermined route on a surface (10) wherein several objects (9) are analysed consecutively The different images are captured in one shot using a digital image capturing device (3) and the images obtained are: Aibedo, Gradient, Range Map, Colour and NIR images which can then be processed and used as an aid to obtain a 3D reconstruction of the object.
