Laser system for controlling glass drawing
speed
|
Application domain
The
system is designed for control of glass drawing processes. |
Operating principle
The system is based on the correlation method of measuring motion
speed. The first photodetector of a CCD-camera reads image of a
glass-sheet edge at fixed time intervals. The images acquired are
digitized and compared to each other. The distance passed by the
glass edge in a time interval between frames and, hence, the glass
movement speed, is calculated from the position of the maximum of
the correlation function in the selected image zones.
Simultaneously, by processing of the image from the second
photodetector the transverse displacement of the glass tape is
calculated. |
The system consists of
-a TV camera with two CCD-linear arrays and image processor;
-a semiconductor laser illuminator;
-a control and display panel equipped with a graphic display, a numeric
speed value indicator and a linear indicator of the glass
displacement value. The control panel forms input signals for the
automatics which controls the glass drawing process line and
transmits information to workshop supervisor’s PC;
-an optical extender and a blind which reduce effects of extraneous
light sources.
