System and method for estimating tuna caught by species on board fishing vessels

摘要

System and method for estimating tuna caught by species on board fishing vessels. The system comprises: # - means capturing images (10) to capture color images of tuna in transit through a passageway (40); # - lighting means (20) for illuminating the passageway (40) diffused light; # - a control module (30): # - draw the outline of the individuals in the images; # - generate the hidden parts of partially hidden individuals; # - get geometric parameters of each individual by pattern matching Geometric; # - obtaining parameters coloring of each individual, extracting the percentage of color band; # - estimating tuna species to which the individual belongs, using the geometrical parameters and coloring of each tuna as input of a neural network artificial relating morphological characteristics, shape and color of tuna species; # - estimating tuna caught by species.
