AUTOMATED METHOD AND SYSTEM FOR THE CLASSIFICATION OF FROZEN TUNA ACCORDING TO SPECIES

摘要

The invention relates to an automated method and system for the classification of frozen tuna according to species, said tuna entering a scanning zone on a conveyor belt (22). The system comprises at least one laser emitter (24) for emitting a laser beam (28) onto the tuna (1), image capture means (26) for capturing three-dimensional images of the laser beam (28) projected onto the tuna (1), and data processing means for: detecting the laser beam (28) in each image; obtaining the rough profile (27) of the tuna from the detected laser beam (28); generating a three-dimensional point cloud (29) of the tuna, from the rough profiles obtained (27); breaking down the three-dimensional point cloud (29) into geometric parameters corresponding to measurements and relationships that define the biometrics of the tuna and its species; estimating the tuna species using a decision tree and a comparison of the geometric parameters of the tuna with a series of reference measurements and relationships.
