AI vision for industrial metrology

3D precision at the price of 2D hardware

inTens-Vision is an end-to-end platform focused exclusively on automated part inspection and dimensional accuracy. We train neural networks 100 % on synthetic CAD data in order to capture parts via 6D pose estimation — purely for exact spatial localisation. The actual measurement of dimensional accuracy (tolerances, distances, edge dimensions) is then performed by classic, subpixel-accurate edge tracing – executed highly efficiently on an NVIDIA GPU right inside the control cabinet.

System architecture

End-to-end AI vision platform across three core domains

Central management & training in the web UI, edge inference and metrology on the Jetson, data storage and traceability in a modern NoSQL structure – designed as one continuous loop, not as an isolated solution.

01 Web UI · Cloud

Central management, CAD database & synthetic training

Everything starts with the design data – not with the production line. The inspection task is created virtually while the factory is still being built.

  • STEP / IGES
  • ONNX / TensorRT
  • React Flow
  • Domain randomization
  • Central CAD database

    Central management of all 3D CAD models (STEP/IGES) – logically linked to the neural networks trained on them, their weights (ONNX/TensorRT) and the matching inspection configurations.

  • Virtual annotation (no-code)

    Users upload the CAD model and mark the features, edges, holes and distances to be inspected by drag and drop – directly on the 3D model or on rendered ideal views.

  • Automated synthetic pipeline

    An integrated renderer automatically generates thousands of photorealistic training images from the CAD model. Physically photographing parts is no longer necessary at all.

  • Domain randomization (sim-to-real)

    While rendering, the software automatically varies textures, metallic reflections, image noise, shadows and changing ambient light scenarios. The CNN becomes robust for daily shop-floor conditions without a single real photo.

  • Visual pipeline editor

    Using an intuitive flow chart, users define the logical inspection sequence: trigger → pose estimation → measure feature A → tolerance check → inspection report.

02 Edge · Control cabinet

Edge inference & hybrid metrology

On the line, two methods work hand in hand: the AI understands the position of the part, classic image processing delivers the incorruptible measurement.

  • NVIDIA GPU
  • 3 × 2 MP global shutter
  • Telecentric optics
  • Subpixel
  • Hardware basis

    A compact NVIDIA GPU for high-performance edge inference directly inside the control cabinet – connected to up to three 2-megapixel cameras: global shutter against motion blur, telecentric lenses for edges free of perspective and distortion.

  • 6D pose estimation (CNN)

    The CNN determines the exact three-dimensional position and orientation of the part (X, Y, Z + rotation) within milliseconds. Thanks to the intrinsic camera calibration stored at the factory, the pose is translated directly into metric data – the error-prone alignment relative to the conveyor belt is no longer needed.

  • Hybrid edge tracing

    The inspection features defined in the web UI are projected onto the real edge image with mathematical precision, based on the live 6D pose. A rule-based edge detection algorithm traces the contours with subpixel accuracy and delivers the final, tamper-proof millimetre measurements.

03 OT / IT infrastructure

Deployment, communication & data storage

What works on one line runs on all of them with a single click. And every measurement is retained as a structured data record.

  • OTA update
  • OPC UA / PROFINET / MQTT
  • NoSQL
  • Cloud-native OTA deployment

    Fully automated compilation of the pipeline including model optimisation via NVIDIA TensorRT – containers and models are then pushed straight to the edge devices in the factories via OTA update.

  • Line PLC integration

    Native OT interfaces (OPC UA, PROFINET, MQTT) on the Jetson transmit measurement results – OK/NOK and tolerance values – to the higher-level machine control within milliseconds.

  • NoSQL database & traceability

    Structured storage of all measurement reports (timestamp, part number, metric values), linked to the compressed image crops of the measured contours. Complete traceability and statistical process control (SPC) for early detection of tool wear.

We take the sim-to-real problem seriously

The leap from a perfect CAD rendering to a real image – scratches in the metal, minimal differences in reflection – is the biggest mathematical hurdle for a CNN. We address it with rigorous domain randomization: shadows, noise and textures are varied extremely during rendering so the network does not fail in a real factory.

Measuring stays mathematics, not an AI estimate

Industry rightly does not yet trust "pure AI" for measurement. That is why our approach is deliberately hybrid: the AI handles 6D pose detection, the actual measurement comes from classic subpixel edge tracing. Comprehensible, reproducible, auditable.

Market gaps

Five gaps we close in practice

Every one of these gaps costs manufacturers time, money or data quality today. On the left the market status quo, on the right our technical answer.

01

The time gap

Zero time to production thanks to CAD models

The challenge

Production lines often have to stand still, or prototype parts have to be built laboriously, just to capture hundreds of images for AI training.

Our solution

Because we train purely on synthetic CAD data, our software is ready before the first real part comes off the machine. Customers set up the inspection pipeline virtually while the factory is still being built – simultaneous engineering instead of waiting.

0 days

downtime for data collection

02

The complexity gap

True 3D pose detection with 2D cameras

The challenge

When complex parts tilt or rotate in space, classic 2D measurement windows can fail. As a rule this is solved with extremely expensive 3D hardware (laser, structured light).

Our solution

Via 6D pose estimation our system understands how the part is tilted in space from the image of a 2-megapixel camera alone. Virtually annotated edges are projected back onto the real 3D pose with mathematical precision: 3D intelligence at the price of 2D hardware.

2 MP

camera instead of a 3D laser

03

The scaling gap

OTA & fleet management instead of USB sticks

The challenge

Managing machine vision systems in factories feels like IT from 2005: updates are installed locally via USB stick or through rigid network drives.

Our solution

Our OTA architecture on top of the web UI breaks these silos open. A single quality engineer at headquarters creates an optimised pipeline and rolls it out to 50 Jetson systems in factories worldwide with one click.

1 click

for the entire fleet

04

The hardware cost trap

Embedded AI with Jetson instead of premium controllers

The challenge

Highly specialised controllers quickly cost €20,000 and more. Industrial PCs with expensive NVIDIA graphics cards are often required in the control cabinet.

Our solution

Our standard hardware is an extremely cost-efficient powerhouse with a module price below €1,000. The fact that it processes up to three 2 MP global shutter streams in parallel cuts hardware costs massively – and makes the system attractive for mid-sized companies too.

< €1,000

module price instead of a €20,000 controller

05

The data treasure gap

Modern NoSQL structure instead of Windows folders

The challenge

Established systems often discard image data or dump it unstructured into Windows folders. Searching millions of measurements for patterns – "show me every image where dimension X deviated by more than 0.2 mm" – becomes impossible.

Our solution

By natively storing measurement reports together with the exact image crops in a NoSQL database (MongoDB, CouchDB), we enable our customers to do real predictive maintenance and gapless traceability.

analysable measurement history

Core selling points

Five USPs that make the difference

Why quality managers, maintenance teams and purchasing can all agree on this platform.

  • 01

    Zero time to production

    Complete independence from real image data

    No production downtime, no photographing prototypes to collect training data. The system is 100 % CAD-based and ready before the first real part comes off the line.

  • 02

    3D precision at a 2D price

    AI-based 6D pose instead of expensive 3D sensors

    The 6D pose estimation dynamically computes positional changes and tilts in space. That eliminates the need for expensive and delicate 3D profile laser sensors or structured light projectors.

  • 03

    Zero calibration & plug-and-play

    MTTR close to zero when service is needed

    Combining factory-side intrinsic calibration with a live 6D pose removes the rigid alignment of the camera to the conveyor plane. In a service case the camera is simply swapped, without any local calibration effort.

  • 04

    Enterprise fleet management

    Central control instead of isolated systems

    No more servicing individual industrial PCs by USB stick. New inspection pipelines and optimised models are rolled out worldwide to every line via OTA update from a central web UI, in one click.

  • 05

    Maximum acceptance through a hybrid approach

    AI locates, classic mathematics measures

    A perfect division of labour: the AI handles localisation and understanding of the complex part, while classic subpixel mathematics (edge tracing) computes the dimensions incorruptibly. That creates immediate trust with quality managers.
