Long confined to the worlds of heavy industry or aerospace, the digital twin is now establishing itself as a cross-cutting technological standard, capable of transforming the way companies observe, understand, and manage their environments. At XXII, we have taken the bet on a visual, accessible, and real-time approach, driven by computer vision.

What exactly is a digital twin?

A digital twin is a virtual replica of a physical environment, powered in real-time by data from sensors, business systems, or videos. It is not just a simple static 3D model, but a living, dynamic, connected twin.

It can represent:

• a building or infrastructure,

• a public space, an intersection, a sensitive area,

• a production line, an industrial site,

• or even a store, a performance venue, a campus...

The goal? Provide a comprehensive, contextual, and actionable view of what is happening here and now, with a history and predictions.

Augmented view: video as the primary source

At XXII, we believe that video is the universal sensor par excellence. Already present in most environments, it is becoming — thanks to computer vision — a rich, structured, and useful data source.

By transforming each camera into a smart sensor, we are able to:

• locate objects, people, or vehicles in real-time,

• analyze behaviors and flows,

• detect anomalies or incidents,

• feed a precise and always up-to-date digital twin.

Use cases in all sectors

Smart cities

• Visualization of pedestrian and vehicle flows in real-time.

• Analysis of public space occupancy.

• Supervision of sensitive or high-stakes areas.

Industry

• Monitoring production processes.

• Visualization of machines and operators in a workshop twin.

• Detection of anomalies on production lines.

Retail & commercial spaces

• Mapping customer journeys in-store.

• Detection of congestion, queues, risky behaviors.

• Tracking attendance and time spent by area.

Tertiary & security

• Intelligent management of buildings (access, density, occupancy).

• Instant reaction in case of abnormal behaviors or intrusions.

• Management of security or maintenance operations from a centralized view.

A centralized platform: the role of CORE

Our CORE platform allows for the aggregation of all these video streams to construct a unified digital twin, viewable from a single interface. The user can:

• explore areas via an interactive map,

• receive smart alerts in case of deviations or danger,

• generate visual reports to support their decisions,

• or even manage multiple sites simultaneously from a central cockpit.

From monitoring to continuous optimization

The digital twin is not just for viewing. It also enables:

• analyzing historical data to understand root causes,

• crossing video data with business KPIs,

• simulating improvement scenarios (occupancy, journeys, security...),

• and acting faster thanks to contextual alerts.

The future: predictive, descriptive, prescriptive

With the gradual integration of visual language models (VLM), the digital twin becomes even more powerful:

“An unusual gathering is forming at the north entrance, not anticipated in the usual scenarios. Monitoring recommended.”

These models do not just see: they understand, explain, and suggest actions.
