Fish genus distinction central processing unit

PROBLEM TO BE SOLVED: To securely decide the kind and size of a fish by recognizing the surface pattern of the fish body and its pectoral fin shape by a reflected light image pickup mechanism and recognizing the shape of the fish body by the transmitted light image pickup mechanism. SOLUTION: A camera box 13 is equipped with the reflected light image pickup mechanism 101 which picks up reflected light from the fish body 12 by a camera 16 from right above the fish body 12. Further, the camera box 14 is equipped with the transmitted light image pickup mechanism 102 which picks up transmitted light including the silhouette of the fish body 12 by a camera 18 from right above the fish body 12. The reflected light image pickup mechanism 101 processes the image picked up by the camera 16 to extract feature quantities of the fish body surface pattern and pectoral fin shape. Further, the transmitted light image pickup mechanism 102 processes the image picked up by the camera 18 to extract feature quantities of the fish body shape. Then a fish body kind deciding means 21 is previously stored with a decision function for deciding fish kinds and inputs the extracted feature quantities to the function by the reflected light image pickup mechanism 101 and transmitted light image pickup mechanism 102 to decided the kind of the fish body 12.
