Centre for Digital Built Britain completed its five-year mission and closed its doors at the end of September 2022

This website remains as a legacy of the achievements of our five-year foundational journey towards a digital built Britain
 
Title card for Teaching a Computer to See video

To asset owners and managers, understanding how people move through and use the built environment is a high priority, enabling better, more user-focused decisions. However, many of the methods for getting these insights can feel invasive to users of the built environment. The latest output from Digital Twin Journeys looks at how a researcher at the University of Cambridge has solved this problem by teaching a computer to see. Watch the video to learn more.

Working from the University of Cambridge Computer Laboratory, Matthew Danish is developing an innovative, low-cost sensor that tracks the movement of people through the built environment. DeepDish is based on open-source software and low-cost hardware, including a webcam and a Raspberry Pi. Using Machine Learning, Matthew has previously taught DeepDish to recognise pedestrians and track their journeys through the space, and then began training them to distinguish pedestrians from Cambridge’s many cyclists.

One of the key innovations in Matthew’s technique is that no images of people are actually stored or processed outside of the camera. Instead, it is programmed to count and track people without capturing any identifying information or images. This means that DeepDish can map the paths of individuals using different mobility modes through space, without violating anyone’s privacy.

Matthew’s digital twin journey teaches us that technological solutions need not be expensive to tick multiple boxes, and a security- and privacy-minded approach to asset sensing can still deliver useful insights.
