Device and method for rapidly detecting defects of wide glass

Abstract

The invention discloses a device and a method for rapidly detecting defects of wide glass. The automatic conveying table is used for preventing conveying of the detected wide glass; the line-scan digital camera is used for collecting an image of the detected wide glass; the blue linear parallel light source is used for assisting the line-scan digital camera in supplementing light to collect images; and the high-performance GPU processing server is used for efficiently processing the images acquired by the linear array camera to extract the defects of the wide glass. The three linear array cameras are arranged in a front-back staggered manner, so that the full coverage rate of the wide glass is ensured; and the blue linear parallel light source is used for assisting in acquiring images with relatively strong defect contrast, so that the problem of rapid detection of the wide glass defects is effectively solved, and the wide glass defects can be rapidly and efficiently detected at one time. The detection platform is simple and flexible in structure, convenient to use and high in automation degree; meanwhile, the image noise reduction processing of the detection method does not cause great damage to the defect image of the glass, so that the extraction of the glass defect is facilitated, and the reliability is high.

Description

technical field [0001] The invention relates to the field of industrial automation machine vision detection, in particular to a device and method for rapid detection of wide-width glass defects. Background technique [0002] At present, the glass defect monitoring system mainly uses manual or laser detection. Manual detection has problems such as high cost, low detection efficiency, high false detection rate, and people are prone to fatigue. Laser detection uses the principle of Moore interference for detection, and its detection is easy. Affected by external interference, the detection accuracy is affected. The principle of moiré interference is that the moiré fringes in the grating are relatively thin. Complicated computer image processing technology to process interference pattern fringes will consume a lot of detection time, and the detection cycle is very slow. Therefore, the present invention proposes a wide-width glass defect rapid detection device and method to solve...
