- Abstract:
- The techniques for digital image acquisition and digital image processing used to identify defects in transparent elements are described in the paper. The block diagram of the test set-up, algorithm of the software developed for identifying geometrical parameters of defects are presented here. The set-up, presented in the paper is proposed for glass quality production control at final and intermediate production line of double glassed windows. The other applications are foreseen. One of the very important feature is calibration of the image with the use of reference glasses, light correction and adjusting parameters of the set-up according to requirements. Calibration is achieved with the of use patterns prepared ahead of time and also with a use of the same set-up. Glass can be categorised depending on number of defects and percentage of defected area or can be disqualified at production line if any permanent defect is found in observed element.
