Visual Inspection Equipment
LCD Display Metrology
Surface features such as scratches, spots and pits are still inspected manually, which raises inspection cost and brings misjudgment, missed defects, low accuracy and inconsistent standards. This system applies algorithms for LCD defect inspection, including camera calibration, image correction and pattern matching, with a simple template that accounts for two types of distortion to reduce image distortion.
- Minimum defect resolution
- 0.008 mm
- Inspection speed
- 16 s/PCS
- Max inspection size
- 150×300 mm
Specifications
- Defect types
- Scratches, edge chipping, pitting, bubbles and other defects
- Suitable products
- LCD screens
- Inspection method
- Inline / offline
- Inspection system
- VisionOne software platform
Highlights
Balanced: a good balance of inspection speed and accuracy
Image processing: image segmentation, edge-feature extraction, mathematical morphology and other analysis techniques
