The width measuring system adopts dual industrial CCD cameras to proceed the online measurement of the steel plate on the roller bed by using the principle of stereo vision technology, and combines the high-speed digital signal processing technology and programming software to process the signals accordingly, and displays the relevant data and measurement curves, so that we can realize precise control of the steelmaking process during production.

The system realizes the width measurement of the slab through the line scan cameras installed on both sides of the gantry slab, and the measurement data is transmitted to the host system through the optical fiber. Accurately calculate the actual width of the slab and the width deviation of the slab from the data collected by the linear array CCD camera with up to 8K pixels and the relative position of the double linear array CCD cameras installed on site. Then we can the actual parameter data and allowable deviation parameters of the slab by using the host system software part, so as to realize the alarm control.
