Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO EFICAZ Y A UN APARATO (20) PARA DETERMINAR LA LOCALIZACION Y LA ORIENTACION APROXIMADA DE UN CODIGO DE BARRAS (33) SOBRE UN SUSTRATO (14). EL PROCEDIMIENTO DE LA INVENCION ES REALIZADO PREFERENTEMENTE POR UN LOCALIZADOR DE CODIGO DE BARRAS OMNIDIRECCIONAL QUE COMPRENDE UN CIRCUITO INTEGRADO ESPECIFICO DE APLICACION QUE INCLUYE UNA O MAS SISTEMAS DE COMPUERTAS PROGRAMABLES DE CAMPO (FPGAS). LA IMAGEN DIGITAL ES UNA REPRESENTACION DE UN BIT (POR EJEMPLO BLANCO/NEGRO) DE UNA IMAGEN DE VIDEO EN ESCALA DE GRISES DE OCHO BITS ESTANDAR PRODUCIDA POR UNA CAMARA CCD (16). EL USO DE UNA SEÑAL DE VIDEO DIGITAL DE UN BIT REDUCE LA CANTIDAD DE MEMORIA DE ALMACENAMIENTO DE MASA REQUERIDA PARA ALMACENAR MEMORIA DE CODIGOS DE BARRA Y FACILITAR LA MANIPULACION DE LA SEÑAL DE VIDEO POR EL CIRCUITO INTEGRADO ESPECIFICO DE APLICACION. EL LOCALIZADOR DE CODIGO DE BARRAS OMNIDIRECCIONAL (20) PROCESA, EN TIEMPO REAL, UNA SEÑAL DE VIDEO DIGITAL (19) QUE DEFINE UNA IMAGENEN PIXELS (30) DE UN TRANSPORTADOR QUE LLEVA PAQUETES (14A, 14B) A TRAVES DEL CAMPO DE VISION DE UNA CAMARA CCD (16). EL LOCALIZADOR DE CODIGOS DE BARRAS (20) DIVIDE LA IMAGEN DE VIDEO (30) EN UNA PLURALIDAD DE CELULAS Y PRODUCE DOS SEÑALES DE SALIDA, UNA SEÑAL DE CELULA DE DETECCION DEL CODIGO DE BARRA (21) Y UNA SEÑAL DE CELULA DE ORIENTACION DEL CODIGO DE BARRAS (22) PARA CADA CELULA. UN ORDENADOR HOST (23) RESPONDE A UNA SEÑAL "VERDADERA"DE CELULA DE DETECCION DE CODIGO DE BARRAS (21) PARA UNA CELULA ALMACENANDO LA PORCION DE LA IMAGEN DE VIDEO (30) QUE CORRESPONDE A LA CELULA EN UNA MEMORIA DE ALMACENAMIENTO EN MASA (24). EL ORDENADOR HOST (30) TAMBIEN ALMACENA UNA REPRESENTACION DE LA SEÑAL DE CELULA DE ORIENTACION DE CODIGO DE BARRAS (22) PARA CADA CELULA EN LA QUE LA SEÑAL DE CELULA DE INDICACION DE CODIGO DE BARRAS (21) ES "VERDADERA". EL LOCALIZADOR DE CODIGO DE BARRAS OMNIDIRECCIONAL (20) PERMITE ASI QUE EL ORDENADOR HOST (30) ALMACENE SOLAMENTE AQUELLAS CELULAS DE LA IMAGEN DE VIDEO (309 QUE CONTIENEN DATOS DE CODIGOS DE BARRAS. LOS DATOS DE CODIGO DE BARRAS PUEDEN ENTONCES SUMINISTRARSE A UN LECTOR DE CODIGO DE BARRAS (23) PARA UN POSTERIOR PROCESAMIENTO.
