Abstract

PROCEDIMIENTO Y DISPOSITIVO DE INSPECCION DE PARED DE COSTADO PARA RECIPIENTES. SE GENERA UN SEÑAL DE COMPARACION QUE REPRESENTA LA DIFERENCIA DE MAGNITUD ENTRE DOS SEÑALES DE VIDEO SUCESIVAS REPRESENTATIVAS DE PUNTOS DE INSPECCION ADYACENTES SOBRE UN RECIPIENTE. LA SEÑAL DE COMPARACION ES GENERADA COMO COCIENTE ENTRE LAS DOS SEÑALES DE VIDEO. EL DENOMINADOR DE ESTE COCIENTE ESTA CONSTITUIDO POR LA SEÑAL DE VIDEO DE MAYOR MAGNITUD DE AMBAS. LA SEÑAL DE COMPARACION GENERADA DE ESTE MODO ES INSENSIBLE A VARIACIONES GLOBALES DE LUZ A TRAVES DEL RECIPIENTE.
