Social Distancing Detection Tool Using Deep Learning

The COVID-19 pandemic accelerated the adoption of Artificial Intelligence and Computer Vision technologies for public health and safety applications. One of the most impactful innovations was the Social Distancing Detection Tool, which uses Deep Learning and Computer Vision to monitor physical distancing between individuals in real time.

By analyzing video feeds from CCTV cameras and surveillance systems, these tools can identify people, calculate distances, and generate alerts whenever social distancing norms are violated.

In this guide, we'll explore how Social Distancing Detection works, the technologies behind it, implementation approaches, and real-world applications.
