Abstract

Este invento propõe num sistema para tirar medidas de pescado, que compreende três elementos centrais: um projetor de luz estruturada, uma câmara e uma superfície onde o pescado está posicionado. Por via da triangulação dos raios de luz projetados e observados pela câmara, o sistema produz sucessivos mapas tridimensionais do que observa. Contudo, o sistema apenas seleciona e guarda uma malha tridimensional por cada nova amostra de interesse. Isso é essencial para se ter um e um só mapa tridimensional por cada amostra de pescado, e não um conjunto massivo de mapas tridimensionais, desnecessário para o processo de medição. Este invento propõe saber, de forma automática, a cada instante, se existe pescado sobre a superfície visualizada pela câmara e guardar apenas uma vez a malha tridimensional do pescado. A informação disponibilizada na malha tridimensional permite a determinação de distâncias rigorosas entre quaisquer dois pontos sobre a superfície do pescado.
