Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA EXPLORACION DE UN CODIGO DE BARRAS, CONSTITUIDO POR LOS PASOS SIGUIENTES: A) ADQUISICION DE UNA PRIMERA EXPLORACION DE CODIGO DE BARRAS A LO LARGO DE UNA LINEA DE EXPLORACION. B) IDENTIFICACION DE LA FAMILIA A LA QUE PERTENECE EL CODIGO DE BARRAS. C) DETERMINACION DE LA ANCHURA DE AL MENOS UNO DE LOS CARACTERES DE SINCRONISMO. D) CALCULO DE LA ANCHURA ESTIMADA DE CADA CARACTER DEL CODIGO QUE SE EXAMINA, SOBRE LA BASE DE LA ANCHURA DEL CARACTER DE SINCRONISMO CONSIDERADO. E) DETERMINACION DE UN CARACTER DESPUES DE UNO DE LOS CARACTERES DE SINCRONISMO, CONTANDO UN NUMERO DE M ELEMENTOS, IGUAL AL NUMERO DE ELEMENTOS QUE CONSTITUYE CADA CARACTER EN LA FAMILIA PERTENECIENTE IDENTIFICADA. F) DETERMINACION DE LA ANCHURA DE DICHOS CARACTERES SIGUIENTES: G) COMPARACION DE SI LA ANCHURA DE DICHO CARACTER SIGUIENTE DIFIERE DE LA ANCHURA ESTIMADA DE UNA MAGNITUD INFERIOR CON RESPECTO A UNA TOLERANCIA PREFIJADA. G1) SI DICHA COMPROBACION PROPORCIONA UN RESULTADO POSITIVO, IDENTIFICACION DE DICHO CARACTER Y REITERACION DE LOS PASOS (E,G) INCLUSIVE, HASTA QUE SE ALCANCE EL OTRO CARACTER DE SINCRONISMO. G2) SI DICHA COMPROBACION DA UN RESULTADO NEGATIVO, ETIQUETADO DE DICHO CARACTER SIGUIENTE, COMO UN "CARACTER INCODIFICABLE".
