HypeVR Crazy Camera Rig Captures Volumetric VR Video (14 Cameras)

HypeVR is working to bring live-action volumetric 360 video to VR. The company’s crazy camera rig, built to capture the necessary data, is a mashup of high-end cameras and laser scanning tech.

HypeVR recently shot a brief demonstration of the output of their rig, which they say can capture ‘volumetric’ VR video that allows users to move around in a limited space within the video, similar to Lytro’s Light field capture which we saw the other day. Traditional 360 video capture solutions don’t allow any movement, effectively locking the user’s head to one point in 3D space, reducing comfort and immersion.

The HypeVR rig used to capture the footage appears almost impractically large; consisting of 14 high-end Red cameras and a Velodyne LiDAR scanner, HypeVR says the rig can “simultaneously capture all fourteen 6K [Red cameras] at up to 90fps and a 360 degree point cloud at 700,000 points per second.”

With similar capture approaches we’ve seen in the past, the video data is used to ‘texture’ the point cloud data, essentially creating a 3D model of the scene. With that 3D data piped into an engine and played back frame-by-frame, users can not only see live-action motion around them, but also move their head through 3D space within the scene, allowing for much more natural and comfortable viewing.

The most common method for enabling movement inside a space is through photogrammetry. One of the more famous companies in that space is Farm51, who are known in the industry for creating Chernobyl VR. Their work has involved multiple trips to Chernobyl to photograph thousands of images into a full 360 immersive Virtual Reality experience.

Now we see that the next generation in 360 VR creation may well come from vendors like HypeVR who say that this massive camera platform is not the only option for capturing volumetric VR video. The company’s purportedly patent pending capture method is camera agnostic, and can be applied to smaller and more affordable rigs, which HypeVR says are in development.

So while the time consuming process for 360 immersive video from real environments is still reliant on the photograph, we can most certainly keep an eye out for vendors like HypeVR to see where they take us next.
