This paper presents an attempt to improve efficiency of cut tile measurement function by developing
an ‘electronic eye’ device using image processing techniques. The automated system consists of a mechanical
unit and an image processing unit. A conveyer belt used to move cut tiles one after the other. The camera unit
situated above the conveyer belt is directly connected to a computer for image acquisition. Constant light
condition was maintained by use of an external light system. The developed algorithm was capable of capturing
images of the tiles moving on the conveyer belt automatically. Then image processing techniques were applied
to calculate pixel length and pixel width of a cut tile. These pixel values were converted to length and width in
mm scale and data saved in a text file. If the cut tile dimensions were not in the given range, the system sounds
an alarm. The system presented in this paper is capable of measurement of tile dimension 0.4 mm of least
measurement and measurement time is reduced from 20 s to 2.5 s compared to manual method. Furthermore,
the number of employers can be reduced to one compared to work of three people involved in manual method.
