Project Challenge

Scenario background and key pain points

  • Modules are large and reflective, so local defects are affected by ambient light and camera angles.
  • Frame, ribbon, label and glass defects differ and require region-specific modeling.
  • Inspection results need unified records by batch, process and defect type.
Technical Approach

JIVISION technical approach

  • Divide inspection regions by module structure and design multi-angle capture with stable illumination.
  • Build defect detection, region segmentation, label recognition and abnormal-grade judgment flows.
  • Output defect snapshots, coordinates, classification results and data-feedback records.
Operating data and final acceptance indicators are confirmed through customer samples, onsite tests and agreed acceptance criteria.
