Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the concrete implementation of the present invention is described in detail:

[0026] attached figure 1 It is the overall structure diagram of the glass detection device, mainly including 1 support stand 2 hood 3 camera 4 light source 5 glass to be tested 6 proximity switch 7 host computer 8 switch 9 motor 10 pulley 11 transmission belt, set 5 glass to be tested to stick and roll when running The side of the platform is operated from bottom to top. After starting the system, the 9 motor starts and drives a driving idler to rotate, and drives the entire rolling platform to move through the 11 transmission belt. When the 5th glass to be tested passes through the 6th proximity switch, the 3rd camera and the 4th light source are automatically turned on, and the 3rd camera takes pictures according to a certain frame rate, and transmits the photo to the 7th host computer for processing; since the image taken by the 3rd camera is...

Abstract

The present invention designs a painted glass defect detection system based on a CCD area array camera, aiming at the current situation that glass manufacturers generally use artificial methods to detect defects on painted glass. It consists of a mobile stage, 5 CCD area array cameras with lenses, 1 strip-shaped red light scanning light source, network cables, switches, host computers, and corresponding fixed facilities. It is mainly divided into two modules, one is the glass image The acquisition module, the second is the glass image processing module, and the two modules are connected through the network. The processing program uses the edge finding operator to judge the glass area and extract statistical defect information.

Description

technical field [0001] The invention relates to the field of online glass detection. Aiming at the current situation that glass manufacturers generally use artificial methods to detect defects on painted glass, a visual online inspection system based on area array cameras is designed. It can detect the number and size of defects on painted glass and identify the types of defects. At the same time, it can meet the requirements of general production lines, with high detection accuracy and stable and reliable detection results. Background technique [0002] For a long time, the defect detection of glass has been carried out offline with special detection equipment. However, some overseas institutions of online detection technology have already reached a considerable level, while the domestic level is relatively backward. [0003] Germany's LASOR company is a company that specializes in providing online detection systems. The company's 2F1 detection system uses digital photog...
