Quality Control & Vision Inspection

Sub-0.05% defect escape on high-throughput lines, with an audit trail regulators love.

Manual QA on high-throughput production lines is a losing battle — humans cannot sustain the concentration required, defects escape, and compliance auditors want more than production teams can produce. Colony deploys computer vision inspection at critical line points, trained on the client's own defect library, with a complete auto-generated audit trail.

01 / The Friction

Human QA cannot keep up. The regulator will not accept “we tried.”

On a line running at 200 units per minute, a QA inspector has 300 milliseconds per unit. Manual inspection is best-effort at 92–95% coverage; escape rates of 0.5–1% are typical. That is fine until a defect reaches a hospital, a supermarket, or a regulator — then it is not. The compliance audit trail is the second problem — assembling it manually consumes days per financial period.

Signals it is you

Defect escape rate above 0.2%

QA team unable to sustain multi-line coverage

Compliance audit preparation running to days

Recurring recalls, complaints, or customer-side rework charges

02 / The Intervention

A camera at every critical point, a classifier trained on your own defect library, and an immutable audit trail.

Colony installs industrial-grade vision cameras at every yield-critical line transition, runs a computer-vision classifier trained specifically on the client's own defect corpus, and streams every classification event to an immutable audit log. Reject decisions happen at line speed; compliance reports are generated on demand.

Components

Component · 01

Industrial vision cameras

GigE Vision, IP69K where required, sub-1ms shutter for high-line-speed applications.

Component · 02

Line-side edge inference

NVIDIA Jetson Orin class — inference at line speed with no cloud dependency.

Component · 03

Client-specific classifier

Fine-tuned on the client's own defect library — no generic model.

Component · 04

Auto-reject actuator

PLC-level integration via OPC UA — reject decisions execute at line speed.

Component · 05

Compliance report generator

BRCGS, FSSC 22000, ISO 22000 and HACCP — auto-populated from the audit ledger.

03 / Tech Stack

What lives under the hood.

Vision Transformer

Fine-tuned ViT on client-specific defect corpus.

Edge inference

NVIDIA Jetson Orin with a TensorRT-optimised runtime; sub-line-speed latency.

PLC integration

OPC UA to any line-control PLC (Siemens, Rockwell, Beckhoff).

Audit ledger

Cryptographic chain-of-custody with regulator-grade export.

04 / The Impact

Reported weekly. Reconciled quarterly.

Defect escape rate driven below 0.05% within one quarter. Scrap and rework savings compound month over month. Compliance audit preparation reduced from days to hours; auditors can pull any inspection event by SKU, time and line in seconds. QA staff redeployed from repetitive inspection into root-cause quality engineering.
