Abstract

SE DESCRIBE UNA ESTACION DE INSPECCION DE CALIDAD AUTOMATIZADA PARA EVALUAR LAS CARACTERISTICAS DE LOS COMPONENTES DEL COLOR DE UN PRODUCTO. LA ESTACION DE INSPECCION INCLUYE UNA CAMARA DE VIDEO EN COLOR, PARA CAPTURAR TOMAS DE VIDEO DE LAS IMAGENES DEL PRODUCTO, Y UN SISTEMA DE CONTROL PARA ANALIZAR ESAS TOMAS DE VIDEO. EL SISTEMA DE CONTROL ESTA PROGRAMADO PARA REALIZAR UNA CALIBRACION DE REFERENCIA Y POSTERIORMENTE UNA CALIBRACION DE LA MUESTRA. DURANTE LA CALIBRACION DE REFERENCIA UN OPERADOR IDENTIFICA LAS AREAS DEL TIPO DE COMPONENTE A PARTIR DE UNA TOMA DE REFERENCIA REPRESENTADA DE UN PRODUCTO TIPICO. EL SISTEMA DE CONTROL CALCULA LAS CURVAS DE DENSIDAD DEL VALOR DEL COLOR A PARTIR DE LAS AREAS IDENTIFICADAS. LAS CURVAS DE DENSIDAD SE CALIBRAN ENTONCES UNAS CON RESPECTO A OTRAS GRADUANDO CADA UNA DE LAS CURVAS DE DENSIDAD MEDIANTE UN FACTOR DE GRADUACION. LOS FACTORES DE GRADUACION PUEDEN SER SUMINISTRADOS DIRECTAMENTE POR EL OPERADOR O PUEDEN CALCULARSE VALORES POR DEFECTO MEDIANTEEL SISTEMA DE CONTROL. LOS VALORES DEL FACTOR DE GRADUACION POR DEFECTO SE CALCULAN SUMANDO EL PRODUCTO DE LA CURVA DE DENSIDAD CORRESPONDIENTE Y UN HISTOGRAMA COMPLETO DE UNA TOMA DE VIDEO DE MUESTREO A LO LARGO DE UNA GAMA DE VALORES DE COLOR. LOS PIXELES INDIVIDUALES SE CLASIFICAN COMO UNA DE ENTRE UNA PLURALIDAD DE TIPOS DE COMPONENTES DE ACUERDO CON LA CURVA DE DENSIDAD CALIBRADA MAS ALTA EN EL VALOR DEL COLOR DE LOS PIXELES.
