Visit Machine Vision<\/strong>, or Computer Vision (OPV)<\/strong>, is a technology that enables machines to analyze and interpret images or videos for a specific purpose. It is the equivalent of the eyes of the automation system, transforming visual information into digital data that can be used to make decisions.<\/p>\n

<\/p>\n

In-depth definition :<\/strong> Machine Vision is a complete system comprising high-resolution industrial cameras, special lighting, image processing software and analysis algorithms. Its role is to acquire, process and analyze images of parts or processes on a production line. With increasing reliance on\u2019Artificial Intelligence (AI)<\/strong> and the Machine Learning<\/strong>, Machine Vision is capable of carrying out inspection, measurement and guidance tasks with a speed, accuracy and consistency that far surpasses human visual capabilities, particularly in harsh environments. Series Production<\/strong> fast. It is an essential component of the Industrial Digitization<\/strong>.<\/p>\n

Revolutionary Applications in Operational Excellence<\/strong><\/h3>\n

The integration of Machine Vision is a major lever for the\u2019Operational Excellence<\/strong>, with direct impacts on the Quality<\/strong>, the Industrial Performance<\/strong> and cost reduction, key areas for SXE Consulting<\/strong> :<\/p>\n

A. Quality control at 100% (Zero Defect Inspection)<\/strong><\/h3>\n
    \n
  • Fault inspection :<\/strong> This is the most common application. Machine Vision can detect surface defects (scratches, cracks, inclusions), labeling errors, assembly non-conformities or color variations. Unlike human inspection by sampling, it enables the inspection of each part (100%)<\/strong> at line speed, guaranteeing the absence of major defects in customer deliveries.<\/li>\n
  • Dimensional Measurement and Conformity :<\/strong> It is used to check that the critical dimensions of a part comply with the tolerances specified in the Manufacturing file<\/strong> and the Technical specifications (CCT)<\/strong>. This check is crucial to the product's assembly and functionality.<\/li>\n<\/ul>\n

    B. Robotic Guidance and Automation (3D Vision)<\/strong><\/h3>\n
      \n
    • Pick-and-Place:<\/strong> 3D Vision enables robots to locate and pick up disordered parts (bin picking<\/em>) or adjust their trajectory in real time. This facilitates the automation of complex or ergonomically difficult tasks, increasing the TRS (Taux de Rendement Synth\u00e9tique)<\/strong> of the cell.<\/li>\n
    • Alignment and positioning :<\/strong> It ensures precise alignment of parts prior to welding, drilling or critical assembly, guaranteeing quality right the first time (First Time Right<\/em>).<\/li>\n<\/ul>\n

      C. Advanced Traceability and Logistics<\/strong><\/h3>\n
        \n
      • Code reading :<\/strong> The Vision Machine can read barcodes, QR codes and Data Matrix Codes (DMC) at very high speed, even on difficult or damaged surfaces. It thus ensures traceability<\/strong> of every component and finished product in the Supply Chain<\/strong>.<\/li>\n
      • Counting and Inventory Control :<\/strong> It can check the exact contents of a package or pallet before dispatch, improving the reliability of the product. Pulled Flow<\/strong> and inventory control.<\/li>\n<\/ul>\n

        Evolution through AI and Machine Learning<\/strong><\/h3>\n

        The addition of the\u2019IA<\/strong> has transformed Machine Vision, moving it from a simple rule-based verification (e.g. \u201cIf the surface is black, reject\u201d) to a more sophisticated intelligent inspection<\/strong> :<\/p>\n

          \n
        1. Variation tolerance :<\/strong> Vision systems based on Machine Learning<\/strong> are trained on thousands of defect examples. This enables them to tolerate normal, acceptable variability (e.g. slight variation in the texture of a raw material) and concentrate on detecting the real, critical defects, reducing false rejects and increasing accuracy.<\/li>\n
        2. Continuous learning :<\/strong> The system learns to recognize new types of defect over time. Each time a human validates an unrecognized defect, the image is added to the training database, ensuring a consistent Continuous Improvement<\/strong> quality control system.<\/li>\n<\/ol>\n

          The Role of Industrial Engineering in Integration<\/strong><\/h3>\n

          Implementing Machine Vision requires specialized expertise. In this case, the engineering consultant is called in to :<\/p>\n

            \n
          • Define Specifications :<\/strong> Choose the right combination of camera, optics and lighting for a given industrial environment (speed, temperature, dirt).<\/li>\n
          • Software integration :<\/strong> Ensure communication and interfacing of Vision data (inspection results) with the MY<\/strong> and the\u2019ERP<\/strong>, so that the data can be used for analysis of the Root Cause Analysis (RCA)<\/strong>.<\/li>\n
          • Sampling strategy :<\/strong> Although the Vision can do 100%, it is sometimes used to control critical points only, after the engineers of the Industrial Engineering<\/strong> have identified the Bottleneck<\/strong> quality process.<\/li>\n<\/ul>\n

            In conclusion, the Machine Vision<\/strong> is the essential tool for\u2019Intelligent Factory<\/strong> to guarantee uncompromising quality and automate inspection tasks, freeing up human resources for higher value-added activities.<\/p>\n
