3D Technology Against Hate in the Stadium

Published on April 01, 2026 | Translated from Spanish

The recent friendly match between Spain and Egypt in Cornellà was marred by Islamophobic and xenophobic chants, now under investigation by the Mossos d'Esquadra. In the face of unanimous condemnation from the authorities, a crucial question arises: how can technology help eradicate these behaviors? The answer lies in the forensic application of 3D tools and audiovisual analysis, capable of transforming a stadium into an intelligently monitored environment to identify and sanction these acts.

Acoustic Triangulation and Forensic 3D Reconstruction 🎯

Current technology allows for a precise response. Through networks of strategically distributed microphones, acoustic triangulation can be used to locate the exact origin of offensive chants with meter-level precision. This data is cross-referenced with the 3D reconstruction of the stadium sector, generated from surveillance cameras or even photogrammetry. The result is an interactive forensic visualization: a 3D model of the stands where the audio can be isolated, the precise location of its origin viewed, and clear, irrefutable evidence presented to a judge, beyond subjective testimony.

Towards Intelligent and Ethical Stadiums ⚖️

Beyond mere sanction, this technological approach promotes prevention. The real possibility of being identified through these tools acts as a deterrent. Integrating these systems into the security of smart stadiums reinforces the commitment that sports be an inclusive space, as pointed out by councilor Berni Álvarez. It is not about mass surveillance, but the ethical use of technology to defend, as indicated by Carlos Prieto, the values of respect and dignity that must prevail.

Can 3D seat mapping and facial recognition technology, integrated into stadiums, effectively identify and deter groups that initiate hate chants?
