Abstract (en)
A device for sorting asparagus (3) according to blooming comprises a light source (25) that directs structured light on asparagus and a camera (21) for taking a picture of the asparagus. The device also has electronic processing facilities (19) to analyze the image of the light projected on the asparagus and on the basis of this analysis to determine a qualification with regard to the blooming. Finally, the device comprises sorting facilities to sort the asparagus on the basis of this qualification. The light source (25) illuminates the asparagus at an angle that differs from the angle at which the camera (21) takes a picture of the asparagus. Preferably the light source (25) illuminates the asparagus at a right angle to the longitudinal direction of the asparagus (3) and the camera (21) takes a picture of the asparagus (3) at an angle with regard to the longitudinal direction of the asparagus (3). <IMAGE>
