GeoVID – Video-Based Crowd Monitoring for Critical Infrastructure and Major Events

Privacy-friendly. Precise. Ready to use right away.

The Challenge: Security in real time

Major events, train stations, airports, industrial facilities – anywhere large numbers of people gather in confined spaces, dangers can arise quickly and without warning. Critical crowding, sudden changes in crowd flow, or bottlenecks often develop within seconds and require immediate, coordinated action.

However, the reality of many current operational situations shows that event organizers, security services, and authorities such as the police and fire department often work with isolated information. This fragmented information base makes it difficult to maintain the necessary overall overview in an emergency – precisely when rapid, interagency coordination is most urgently needed. Furthermore, crowds are highly dynamic. Conventional, analog observation methods are barely capable of capturing these complex developments in a timely manner and evaluating them thoroughly.

Our Approach: An objective situation picture instead of vague estimates

GeoVID is an AI-supported system developed at Fraunhofer IOSB for video-based detection and analysis of crowds (crowd monitoring) in distributed urban environments. The focus is not on the individual, but on the collective behavior of the crowd: crowd density, distribution, directions of movement, and speeds are captured in real time and displayed on a shared, interactive situational picture. This creates an objective, shared situational picture for all stakeholders – without delay and without room for interpretation.

The AI detects people but does not recognize individuals

The AI detects where people are located but does not identify them. It generates a heat map from which the number of people and their density can be determined. GeoVID converts this information into a georeferenced grid (people per square meter). This density data can be displayed on a map without the underlying camera image—that is, completely anonymously.

The principle is illustrated by the three images above, each showing the same situation in a different way, as well as by the following video (Juicy Beats Festival, Dortmund 2024):

Features at a Glance

Real-time analysis
Video data from moving and stationary camera platforms is processed without any noticeable delay. Deep learning algorithms provide precise counts of people and crowd density estimates—significantly more reliable than manual estimates.

Georeferencing
Individuals and groups of people are precisely located in three-dimensional space and displayed on interactive maps. Emergency responders can see at a glance where problems are developing.

Dynamic analysis
The speed and direction of movement of the crowd are continuously tracked. Congestion, bottlenecks, or sudden movements of people fleeing are detected early—before they escalate.

Hierarchical hotspot display
A grid-based visualization that scales with zoom levels enables high-performance data transmission and immediate visual orientation, even for very large areas.

Seamless integration
GeoVID is fully compatible with existing camera infrastructure and is operated via a web-based interface—without costly hardware investments.

Data protection as a fundamental principle, not an afterthought

GeoVID was developed from the ground up based on the principle of “Privacy by Design”:

  • Focus on the collective: The analysis focuses exclusively on the behavior of the crowd, not on individual persons.
  • No storage of personal data: The system operates entirely without storing any personal data. Data is reduced to the absolute minimum necessary to actively protect the rights of data subjects.
 

Interested?

GeoVID is currently in the final phase of development and is available for pilot projects and collaborations. Please contact us – we’d be happy to explain how the system can be used in your specific environment.

Application fields

GeoVID is designed for organizations and institutions that are responsible for the safety of large crowds and rely on a reliable, data-protection-compliant situational picture.

Event organisers and event management

Whether it’s a music festival, a sporting event, or a city festival – anyone who organizes large events bears a great responsibility for the well-being of attendees. GeoVID helps organizers identify bottlenecks and dangerous crowding at entrances, stages, or restroom facilities early on and take targeted action to address them. Crowd flows can be analyzed in real time and precisely managed. The result: a higher level of safety and more efficient staffing.

 

 

Government agencies and organizations with security responsibilities (BOS)

Police, fire departments, and public safety services benefit from a shared, real-time situational picture. Information silos are a thing of the past. High-risk areas are automatically visualized, allowing emergency responders to be directed precisely to the right locations – based on objective AI-generated crowd counts rather than vague estimates.

 

 

Operators of critical infrastructure

At train stations, airports, and industrial facilities, GeoVID ensures continuous monitoring during daily operations. Anomalies in human activity are automatically detected as soon as they emerge. Operators are provided with a preventive tool to defuse critical situations before they escalate. Seamless integration into existing camera infrastructure ensures that no costly retrofitting of the technical infrastructure is necessary.
