关键特征

  The system adopts the international leading high-resolution industrial camera, with custom special three-color filter, combined with the filtering algorithm that meets the human sensory characteristics, can stably detect the defect with a minimum defect size of 26μm and a maximum detectable 10μm. For Mura defects, Quantitative grading, stable detection of 2mm × 2mm, contrast ratio of more than 3% of Mura defects, the device has exceeded the detection quality level of the human eye, and can provide higher detection efficiency. The system can be divided into online and offline modes. At the same time, it can be specially developed according to the production line requirements and various camera numbers can be upgraded to achieve optimal efficiency configuration.
