A detection system based on modulation of line structured laser image of glass comprises processing section (2), control system, and roller conveying mechanisms (5). Detection mechanism (6) provided over entrance of the processing section (201) comprises shell and camera (602) with laser (601) which emits beam on the surface of the glass in the gap between sliding rollers. Focal plane of the camera (602) corresponds to the beam irradiation surface, and signal output terminal of the camera (602) is connected with the control system in such a way that when glass passes the detection area, laser irradiates the glass surface and the line structured laser is modulated based on the glass to form laser modulation image with distribution of light and shade, staggered movement direction, or distorted laser lines. The camera (602) will transmit the captured glass information and parameters to the control system. In the system, the detection mechanism (6), with integral design and compact structure, can be easily fitted over the entrance of the processing section (201), has strong adaptation to other processing means, has no special requirements on incident angle of light and angle of detection surface during detection, and obtains highly accurate data through measurement. |
