Seam Inspection
AI vision that checks every bag for badly sewn seams and missing labels, so defective bags don't reach your customers.
Captic Seam Inspection checks every bag on your line for badly sewn seams, and optionally for missing labels, before it leaves your site. For each bag it returns a pass/fail result with a confidence score, and your line rejects the bad ones.
Why seams are hard to inspect
Manual inspection is slow, inconsistent and expensive, and a single defective bag that reaches a customer can lead to a claim. Traditional vision systems need to be programmed for every defect type, and struggle with the natural variation in bags, print and sewing.
What it does
Detects badly sewn seams on every bag, at line speed.
Detects missing labels, as an option.
Gives a clear result: pass or fail, with a confidence score your PLC can act on.
Logs every inspection. Each image and result is stored, giving you full traceability. Review them in Captic Cloud.
Improves over time. When something changes on your line, such as a new bag type, new print or different lighting, we retrain the model with your images.
At a glance
Inspection time
Under 300 ms per bag
Checks
Seams; labels optional
Output
Pass/fail and confidence score, to your PLC
Camera
Typically an Advantech ICAM-540, mounted over the conveyor
Rejection
By your line, usually the existing check-weigher
Traceability
Every image and result logged
How it works
A trigger from your line tells the system a bag is in view.
The camera captures the bag.
The AI checks the seam, and the label if enabled.
The result is sent to your PLC through the Integration Flow.
Your line, usually the check-weigher, rejects bags that fail.
Setting up
Follow Getting Started to go from delivery to the first inspected bag.
Key settings
Region of interest (ROI): the part of the image that is inspected.
Sensitivity: how strict the inspection is, which trades off missed defects against false rejects.
