 <\/p>\n

The working principle can be summarized in four core steps:<\/p>\n

    \n
  1. Image Acquisition<\/strong><\/li>\n<\/ol>\n
      \n
    • Process<\/strong>: The system captures an image of the object using an\u00a0industrial camera<\/strong>\u00a0and specialized\u00a0lighting<\/strong>.<\/li>\n
    • Key Elements<\/strong>:\n
        \n
      • Illuminazione<\/strong>: Provides stable, uniform illumination to\u00a0highlight features of interest<\/strong>\u00a0and suppress noise.<\/li>\n
      • Telecamera<\/strong>: Converts light into a digital image signal.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
          \n
        1. Image Processing<\/strong><\/li>\n<\/ol>\n
            \n
          • Process<\/strong>: The raw image is sent to an\u00a0image processor<\/strong>\u00a0for preprocessing.<\/li>\n
          • Key Operations<\/strong>:\u00a0Noise reduction, contrast enhancement, edge sharpening<\/strong>\u00a0to prepare the image for analysis.<\/li>\n<\/ul>\n
              \n
            1. Feature Extraction and Analysis<\/strong><\/li>\n<\/ol>\n
                \n
              • Process<\/strong>: The system’s “brain” analyzes the processed image against preset\u00a0standards or templates<\/strong>.<\/li>\n
              • Key Operations<\/strong>:\n
                  \n
                • Measurement<\/strong>: Calculates pixel distances and converts them to real-world dimensions.<\/li>\n
                • Pattern Matching<\/strong>: Compares the image to a known good template.<\/li>\n
                • Recognition<\/strong>: Reads characters, barcodes, etc.<\/li>\n
                • Location<\/strong>: Finds object edges, centers, or feature points.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
                    \n
                  1. Result Output and Action<\/strong><\/li>\n<\/ol>\n
                      \n
                    • Process<\/strong>: The system makes a decision based on the analysis.<\/li>\n
                    • Key Operations<\/strong>:\n
                        \n
                      • Pass\/Fail Judgment<\/strong>: Decides if the object is acceptable.<\/li>\n
                      • Data Output<\/strong>: Sends results to a PLC, robot, or host computer.<\/li>\n
                      • Action Triggering<\/strong>: Often sends an I\/O signal to control a\u00a0reject mechanism<\/strong>\u00a0or guide a\u00a0robot<\/strong>.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

                        Summary: An optical inspection machine uses precise hardware to capture high-quality images and powerful software algorithms to simulate human observation and judgment, ultimately performing inspection tasks with far greater speed, accuracy, and consistency than a human operator.<\/strong><\/p>","protected":false},"excerpt":{"rendered":"
