Industrial Visual Inspection

Defect inspection and reject control

A camera-based quality check for production lines that gives each part a pass or fail verdict on a local computer. Failed parts can be pushed off the line automatically, and results go to the PLC and the MES. It suits factories that want to catch surface flaws, missing parts or wrong labels without sending images off site.

Results reported by the design's authors on their own test setups. Yours depend on the site, so we confirm them in a pilot.

The problem

Why it matters.

Human inspectors tire and judge inconsistently, batch measurement only samples parts, and rule-based vision trips over glare and worn labels, so defects slip through or lines stop for nothing.

The flow

From signal to action.

01SenseTriggerA photo sensor sees the part arrive and fires the camera and a strobe light so the image is sharp.
02SenseStation cameraA GigE, USB3 or existing RTSP camera, or an all-in-one reCamera Pro, captures the part.
03DecideInspection hostA fanless reComputer runs an INT8 defect, assembly or OCR model on every frame.
04ActReject outputOn a fail, an isolated digital output drives a relay that triggers the pneumatic reject arm.
05ConnectPLC and MESVerdicts go to the PLC over Modbus TCP and to the MES as MQTT events, while images stay on the plant network.

Reject output

How it works

Step by step.

01Pick the camera type for each station and choose a host sized to the number of cameras and the line speed.
02Mount the camera rigidly over the part, fix the lighting and add a calibration target if you need sizes in mm.
03Run a trial on the live line to collect your own good and bad samples.
04Retrain or fine-tune the starter model on those samples and set thresholds for your false alarm rate.
05Wire the reject output through a relay and map OK and NG coils in the PLC.
06Go live and review flagged images on the local web panel.

Before you install

A rigid mount over each station with the whole part in the field of view.
Stable lighting, with a strobe synced to a photo trigger on fast lines.
Wired Gigabit Ethernet or PoE from cameras to host, and Ethernet to the PLC.
An external relay for the reject actuator, since the digital outputs cannot drive solenoids directly.
Space for a DIN rail or panel mount near the line, within the host's -20 to 60 °C range.

Good to know

High catch rates need retraining on defect samples from your own line; the starter model is only a baseline.
Size checks are not a certified gauge and cannot replace a CMM.
reCamera Pro is limited to PCB defects and cannot do missing-part or size checks.
Multi-station rollouts and PLC wiring are integration work, usually done with a specialist.

How we deliver it

Paper to site, one team.

01Site surveyWe walk the site, or review photos and drawings, and agree what to measure and where each device goes.
02PilotOne lane, one line or one room first. We tune it on your conditions and agree what good looks like.
03Roll outWe supply the hardware in India with GST invoices, install it, and connect it to the systems you already run.
04SupportSpares, remote checks and model updates, with one team to call when something changes.

Questions

Asked before buying.

Do images leave the factory?

No. Inference runs on the local host and only verdict records go to the PLC and MES.

Can it work with our existing cameras?

Yes, an existing RTSP IP camera can feed the host, mainly for packaging and presence checks. Surface defects usually need a GigE camera with strobe lighting.

Will it work out of the box on our parts?

Only as a starting point. Expect a trial run and retraining on your own defect samples before relying on it.
