Abstract

Sistema y procedimiento automatizado de clasificación de atunes congelados por especie, que acceden a una zona de escaneado por una cinta transportadora (22). El sistema comprende:#- al menos un emisor láser (24) encargado de emitir un haz láser (28) sobre el atún (1);#- medios de captación de imágenes (26) para capturar imágenes tridimensionales del haz láser (28) proyectado sobre el atún (1);#- medios de procesamiento de datos para:#- detectar el haz láser (28) en cada imagen;#- obtener el perfil bruto (27) del atún a partir del haz láser (28) detectado;#- generar, a partir de los perfiles brutos (27) obtenidos, una nube de puntos tridimensional (29) del atún;#- descomponer la nube de puntos tridimensional (29) en parámetros geométricos que corresponden a medidas y relaciones que definen la biometría del atún y su especie;#- estimar la especie del atún mediante un árbol de decisión y una comparativa de los parámetros geométricos del atún con una serie de medidas y relaciones patrones.Automated system and procedure for classification of frozen tunas by species, which access a scanning area by a conveyor belt (22). The system comprises: # - at least one laser emitter (24) responsible for emitting a laser beam (28) on the tuna (1); # - image capture means (26) to capture three-dimensional images of the laser beam (28) projected on tuna (1); # - data processing means for: # - detecting the laser beam (28) in each image; # - obtaining the raw profile (27) of the tuna from the detected laser beam (28) ; # - generate, from the raw profiles (27) obtained, a three-dimensional point cloud (29) of tuna; # - decompose the three-dimensional point cloud (29) into geometric parameters that correspond to measures and relationships that define the biometrics of tuna and its species; # - estimate the tuna species using a decision tree and a comparison of the geometric parameters of tuna with a series of measures and standard relationships.
