Abstract

UNA CAMARA DE VIDEO CCD DE ALTA RESOLUCION (6) SE POSICIONA Y SE ALINEA CON RESPECTO A UN OBJETO ILUMINADO (7) DE TAL FORMA QUE EL BORDE RECTO DEL OBJETO, O UNA LINEA DE JUNTA RECTA ENTRE UNA ZONA DE BRILLO Y UNA ZONA OSCURA DE SU SUPERFICIE, CRUCE EL CAMPO DE VISION DE LA CAMARA EN UNA DIRECCION SUBSTANCIALMENTE PARALELA A LAS LINEAS DE LA MATRIZ ORTOGONAL DE LA CAMARA DE LINEAS Y COLUMNAS DE LOS ELEMENTOS SENSIBLES A LA LUZ, PARA DIVIDIR DICHO CAMPO DE VISION EN ZONAS OBSCURAS Y DE BRILLO. UN ALMACENADOR Y DIGITALIZADOR DE LA TOMA (9) CONVIERTE LAS SEÑALES INDIVIDUALES GENERADAS POR LOS ELEMENTOS EN VALORES GRISES DIGITALES. LOS VALORES GRISES DERIVADOS DE LOS ELEMENTOS DE CADA FILA SE SUMAN MEDIANTE UN COMPUTADOR (10) PARA PRODUCIR UNA MATRIZ LINEAL DE VALORES DE SUMA RELACIONADOS POSICIONALMENTE CON LAS COLUMNAS RESPECTIVAS, Y EL COMPUTADOR DETERMINA ENTONCES LA POSICION DEL BORDE O JUNTA CALCULANDO EL VALOR MEDIO DE DOS DE LOS VALORES DE SUMA SELECCIONADOS RESPECTIVAMENTE DE UNA FILA RECEPTORA DE ENERGIA DE LA ZONA BRILLANTE Y OTRA RECEPTORA DE ENERGIA DE LA ZONA OSCURA Y ESTABLECIENDO UNA POSICION EN LA MATRIZ PARA EL VALOR MEDIO, Y DE ESTA FORMA PARA SUS CARACTERISTICAS, INTERPOLANDO EL VALOR MEDIO ENTRE LOS DOS VALORES DE SUMA INMEDIATAMENTE SUPERIOR E INFERIOR A EL EN MAGNITUD.
