LiDAR head-up display could improve road safety
Researchers from the universities of Cambridge, Oxford and UCL have developed a LiDAR based augmented reality head-up display for use in vehicles.
The technology aims to improve road safety by ‘seeing through’ objects to alert of potential hazards without distracting the driver. Using LiDAR (light detection and ranging) data to create ultra-HD holographic representations of road objects, the images are beamed directly to the driver’s eyes instead of 2D windscreen projections used in most head-up displays.
“Head-up displays are being incorporated into connected vehicles, and usually project information such as speed or fuel levels directly onto the windscreen in front of the driver, who must keep their eyes on the road,” said lead author and Cambridge engineering PhD candidate Jana Skirnewskaja. “However, we wanted to go a step further by representing real objects as in panoramic 3D projections.”
According to the team, early tests show that the images appear in the driver’s field of view according to their actual position, creating augmented reality. Researchers believe this could help drivers to see through visual obstructions in instances such as a large tree or truck hiding a road sign. The study has been published in Optics Express.
