Abstract

UN SISTEMA PARA LA DETECCION SIN CONTACTO DE LAS GRIETAS DE UNA SUPERFICIE PARA PIEZAS DE TRABAJO TALES COMO BOLITAS COMBUSTIBLES NUCLEARES QUE TRANSPORTA LAS BOLITAS DE MANERA CONTINUA A LO LARGO DE UNA TRAYECTORIA ILUMINADA AL TIEMPO QUE LAS HACE ROTAR. UNA CAMARA DE EXPLORACION DE LINEAS REGISTRA UNA SERIE DE EXPLORACIONES DE LINEAS DE LAS BOLITAS Y SE DIGITALIZAN LOS VALORES RESULTANTES DE LA REFLECTIVIDAD DE LAS BOLITAS. LOS VALORES DE LOS PIXELS SE COMPARAN CON LOS UMBRALES DEFINIDOS ADAPTIVAMENTE BIEN ESTABLECIENDO UNA MEDIA Y/O UTILIZANDO UN FILTRO DE RESPUESTA A LOS IMPULSOS FINITOS DE VIDEO PARA GENERAR UN MAPA BINARIO DE PIXELS "BUENOS" Y "MALOS", QUE DEFINE TAMBIEN LOS BORDES DE LA BOLITA EN EL MAPA. UN PROCESADOR CUENTA Y ASOCIA LOS PIXELS MALOS PARA DEFINIR LOGICAMENTE Y EVALUAR MANCHAS DE PIXELS MALOS. EL PROCESADOR VERIFICA LA COINCIDENCIA DE LOS PIXELS DE LOS BORDES CON LA LINEA DE REBORDE NOMINAL QUE MAS COINCIDA CON EL BORDE, PARA ENCONTRAR GRIETAS EN LOS BORDES. SE SELECCIONAN O RECHAZAN LAS BOLITAS ASI EVALUADAS. UNOS ELEMENTOS DETECTORES FOTOGRAFICOS SE NORMALIZAN EN CUANTO A SU GANANCIA Y DESVIACION. EL DESPLAZAMIENTO DEL DATO DE PIXELS CANCELA LA OBLICUIDAD PRODUCIDA AL EXPLORAR LAS BOLITAS EN MOVIMIENTO. UNOS FILTROS DE CONVOLUCION CANCELAN LOS PIXELS MALOS AISLADOS Y AUMENTAN EL CONTRASTE EN EL BORDE. PARA EL PROCESAMIENTO DE LAS AREAS ADYACENTES, SE PUEDE DIVIDIR EN CUADRADOS LA IMAGEN DE PIXELS DE LAS BOLITAS, EVALUANDOSE LAS GRIETAS QUE PUENTEAN LOS CUADRADITOS COMO UNA SOLA MANCHA. EL APARATO SE UTILIZA PREFERENTEMENTE EN LA PRODUCCION DE TUBERIAS PARALELAS PARA ENCONTRAR LOS DEFECTOS QUE PUDIERA HABER EN LAS PAREDES LATERALES Y EN LOS BORDES Y SE PUEDE APLICAR A UNA SERIE DE TABLEROS DE VME MODULARES.
