Glass fragments detector for a jar filling process

The inspection system presented in this paper is a glass fragments detector for a jar filling process. It is based on an important optical property of glass. Namely, intense specular reflections which are produced when the glass is illuminated with proper lighting. Careful control of the lighting environment allows these reflections to occur only when glass fragments are present in the jars. A standard black and white camera is used to measure the luminous intensity of the scene. An electronic circuit processes the video signal in real-time and detects the presence of glass fragments from input images.< >
