Use SolVision's Feature Detection feature to learn the location points that need to be identified on the tray, and then use Segmentation technology to perform optical character recognition (OCR), which can greatly optimize the traditional AOI workflow. It is not restricted by the displacement, skew and character defects of the identification screen, and can accurately identify the source of individual materials. With the increase of the number of learning pieces, the ability of AI to identify characters can also be continuously optimized, making character identification no longer difficult.
