Abstract

METODO DE LOGICIAL CARA VISION ARTIFICIAL EN METALOGRAFIA. TIENE POR OBJETO REALIZAR UN ANALISIS CUANTITATIVO A PARTIR DE MUESTRAS METALURGICAS DE FORMA RAPIDA Y PRECISA. CUENTA CON: UNA PRIMERA FASE DE OBTENCION DE UNA IMAGEN DE LA MUESTRA A ESTUDIAR UNA SEGUNDA FASE DE DIGITALIZACION Y ALMACENAMIENTO DE LA IMAGEN; UNA TERCERA FASE DE CALIBRACION EN LOS DOS EJES DE LA IMAGEN, DETERMINANDO LA RELACION ENTRE PIXELS Y DISTANCIA REAL; UNA CUARTA FASE DE SELECCION DE LAS PARTICULAS QUE PRESENTAN UN NIVEL DE GRIS, DENTRO DE UNOS UMBRALES ESTABLECIDOS, DIFERENTES DEL RESTO DE LA IMAGEN; UNA QUINTA FASE DE CALCULO DE PARAMETROS MORFOMETRICOS DE LOS OBJETOS SELECCIONADOS; UNA SEXTA FASE DE SELECCION DE UMBRALES EN TRES PARAMETROS; UNA SEPTIMA FASE DE SOBREIMPRESION DE UNA REJILLA PARA CALCULO DE PARAMETROS EXTEREOLOGICOS. LA CUARTA FASE PUEDE CONSISTIR EN CONTORNEAR UN AREA, MARCAR DOS PUNTOS EXTREMOS Y DEFINIR DOS SEGMENTOS PARA MEDIR EL AREA, LINEAS Y ANGULOS RESPECTIVAMENTE.
