University of Bath develops VR camera system
- Details
Virtual reality headsets are becoming increasingly popular for gaming, and with the global pandemic restricting our ability to travel, this system could also be a cheap and easy way to create virtual tours for tourist destinations.
Conventional 360° photography stitches together thousands of shots as you move around one spot. However, it doesn’t retain depth perception, so the scene is distorted and the images look flat.
Whilst state-of-the-art VR photography, which includes depth perception, is available to professional photographers, it requires expensive equipment, as well as time to process the thousands of photos needed to create a fully immersive VR environment.
Dr Christian Richardt and his team at CAMERA, the University of Bath’s motion capture research centre, have created a new type of 360° VR photography accessible to amateur photographers called OmniPhotos.
This is a fast, easy and robust system that recreates high quality motion parallax, so that as the VR user moves their head, the objects in the foreground move faster than the background. This mimics how your eyes view the real world, creating a more immersive experience.
Dr Richardt and his team presented the new system at the international SIGGRAPH Asia conference on Sunday 13 December. He said: “Until now, VR photography that uses realistic motion parallax has been the preserve of professional VR photographers, using expensive equipment and requiring complex software and computing power to process the images.
“OmniPhotos simplifies this process so that you can use it with a commercially available 360° camera that only costs a few hundred pounds. This opens up VR photography to a whole new set of applications, from estate agent’s virtual tours of houses to immersive VR journeys at remote tourist destinations. With the pandemic stopping many people from travelling on holiday this year, this is a way of virtually visiting places that are currently inaccessible.”
