Abstract

Se describe un método para detectar un defecto en una lámina de vidrio, que comprende los pasos: (i) dirigir un haz convergente desde una fuente de iluminación sobre una superficie de la lámina de vidrio para iluminar el defecto; (ii) enfocar un dispositivo de captura de imágenes en un primer plano para obtener imágenes del defecto en la lámina de vidrio; (iii) capturar una primera imagen del defecto; (iv) realizar un paso de ajuste; (v) capturar una segunda imagen del defecto. Cada una de las imágenes primera y segunda comprende una primera porción respectiva del defecto iluminado y una segunda porción respectiva debida a la reflexión de una porción del haz desde la superficie del vidrio. En la primera imagen del defecto, la primera porción es más brillante que la segunda porción, y en la segunda imagen del defecto, la primera porción es más oscura que la segunda porción. También se describe el aparato para llevar a cabo el método.
