An augmented reality head-up display system has been developed to enhance road safety, displaying potential hazards as high-resolution 3D holograms directly in a driver’s field of view in real-time.

Presently, heads-up display systems in vehicles are confined to projecting two-dimensional information onto the windshield. This approach, while functional, restricts the depth and scope of the visual data that can be presented to the driver, potentially limiting the system’s effectiveness and user experience.

Researchers from the Universities of Cambridge, Oxford, and University College London (UCL) have created a three-dimensional representation of London’s streets using a 3D laser scanner and LiDAR data.

The team’s advanced system can project holographic representations of road obstacles obscured from a driver’s view, aligning these holograms with the actual size and distance of the real objects. For instance, a road sign hidden behind a large truck would be displayed as a 3D hologram, providing the driver with precise information on its location and content. This 3D holographic projection technology focuses the driver’s attention on the road rather than the windshield, potentially enhancing road safety by real-time projection of road obstacles and potential hazards from various angles.

The team have devised an augmented reality system that merges 3D holographic technology with LiDAR data to display objects within the driver’s view, matching their real-life size and distance. Tested on UCL’s Malet Street, the system transforms LiDAR data into detailed 3D holograms, offering a 360° view of obstacles with accurate depth perception. The system’s rapid scanning and real-time projection adapt to the dynamic nature of busy streets, ensuring up-to-date information.

The researchers emphasize that their study’s unique contribution is the ability to provide a 360° view of road hazards by carefully selecting data points from single scans of specific objects, such as trucks or buildings. This method significantly enhances the accuracy of hazard assessment. 

The team is presently working with Google to advance the technology for real-world car testing. They aim to conduct road tests, whether on public or private roads 2024.

  1. Gogreen with Solar sourced charging stations with lower service amount just sufficient enough for salary of a operator. No leverage of power charges and maintenance costs. I commented in my first comment but couldnt complete and disappeared
