Why advanced imaging is the future of manufacturing quality control
In manufacturing, manual inspections have clear limits in speed and accuracy. This is why advanced imaging technology is becoming a key part of this process.
The key benefit of advanced imaging lies in catching issues that are hard to see with the naked eye. With the right cameras and software, it’s possible to elevate manufacturing quality control to new levels of precision.
How Does Advanced Imaging Work?
Advanced imaging starts with using camera hardware to create raw data. Then, you use a flexible vision software platform to extract actionable insights via:
- Multi-sensor compatibility
- Comprehensive processing libraries
- Graphical programming environments
- Hardware-agnostic deployment
- AI and deep learning
The key to making this approach work is to choose the right software for your needs. For example, your image measurement software should be easy to use and integrate with other key software solutions.
Why Is Advanced Imaging So Important?
There are plenty of reasons why advanced imaging technologies are the future of quality control. Here are five key examples.
1. Defect Detection
First, advanced imaging allows manufacturers to identify hidden product defects. This is done with 3D vision, which captures the shape and volume of items. That way, it’s much easier to notice cracks and surface irregularities.
Hyperspectral imaging also plays a role in defect detection. It reveals chemical signatures that help with detecting internal bruising or spoilage.
2. Automated Sorting
Quality control advancements extend to enabling consistent sorting and grading. The idea is to automate complex grading tasks and reduce waste as much as possible. Advanced imaging systems make this possible via:
- 3D imaging: It helps with sorting by volume and size
- Color cameras: They identify discoloration or blemishes
- Hyperspectral imaging: It evaluates moisture levels, sugar content, etc.
3. Label Verification
Accurate and legible labeling is essential for regulatory compliance and protecting brand reputation. High-res 2D cameras equipped with OCR and OCV can verify any printed text. This ranges from expiry dates to allergen information.
If there are still issues with legibility, AI-enhanced vision tools can help. They can compensate for variations in lighting, print quality, and so on.
4. Packaging Integrity
Ensuring packaging integrity often plays a key role in improving manufacturing processes. Thermal imaging can detect heat patterns to identify improperly sealed containers or faulty seals. Beyond that, 2D/3D vision systems can:
- Validate fill levels
- Verify packaging consistency
- Correct closure of lids or caps
5. Foreign Material Detection
Contamination poses serious health risks in food products. Thermal imaging allows you to identify foreign objects with different heat retention characteristics. This is particularly effective during cooled or heated processing.
Meanwhile, hyperspectral imaging can detect a wide range of non-metallic contaminants. Traditional metal detectors can take care of the rest.
Manufacturing Quality Control Made Easy
As far as manufacturing industry innovations go, advancing imaging is clearly here to stay. In fact, as imaging sensors become more and more affordable, their use in manufacturing quality control will only keep growing.
