Abstract

Un sistema ad alta risoluzione per la manipolazione di oggetti serve per differenziazione - identificazione degli oggetti, creando un profilo degli oggetti. Gli oggetti vengono singolarizzati su un trasportatore ed esplorati da un insieme lineare di unità CCD (2048 pixel per pollice - circa 81 pixel per mm) ad una frequenza di esplorazione di 10 MHz. Le transizioni di pixel corrispondenti a punti ai bordi degli oggetti vengono trasformate in un singolo valore di conteggio da un contatore che è sincronizzato con il dispositivo d'esplorazione ("scanner"). Un microprocessore con una memoria buffer "primo ad entrare, primo ad uscire" ("first in, first out") necessita solo di una capacità atta a trattenere i valori di conteggio anziché tutti i dati dei pixel.
