Abstract

SE PROPORCIONA UN SISTEMA DE CREAR UNA IMAGEN DE LOS CONTORNOS DE LA SUPERFICIE DE UNA PIEZA METALICA DE TRABAJO (10), COMO UNA BANDA DE MOLDE CONTINUA, QUE INCLUYE UNA LAMINA DE LUZ PLANA DE FRECUENCIA UNICA (28) DIRIGIDA PARA INCIDIR SOBRE UNA SUPERFICIE (12) DE LA PIEZA DE TRABAJO (10), Y UNA VIDEOCAMARA (30) SITUADA EN FORMA ADECUADA PARA OBSERVAR LA SUPERFICIE (12) SOBRE LA QUE INCIDE LA LUZ, DE FORMA QUE, CUANDO LA SUPERFICIE (12) DE LA PIEZA DE TRABJO (10) ES PLANA, LA VIDEOCAMARA (30) DETECTA UNA LINEA RECTA, CUANDO LA SUPERFICIE (12) ES IRREGULAR, LA VIDEOCAMARA (30) DETECTA UNA LINEA NO RECTA Y CREA UNA IMAGEN BIDIMENSIONAL DE LA LUZ DETECTADA, SUMINISTRANDO ESTA SEÑAL A UN PROCESADOR (34), EL CUAL A SU VEZ CREA UNA IMAGEN DE LA PIEZA DE TRABAJO (10) QUE PUEDE VISUALIZARSE MEDIANTE UN MONITOR DE VIDEO (36, 39) Y/O UNA IMPRESORA (38). EL PROCESADOR (34) EXTRAE UNA DIVERSIDAD DE VALORES PARAMETRICOS CUANTITATIVOS DE LAS IMAGENES.
