I saw the image you’re referencing yesterday. The unit appeared to be a plane, briefcase sized. It had two fisheye lenses about 10cm diameter each and separated by what I expect is an average human IPD. So I think that unit was simply capturing 180 degree stereo video. Not enough to compute volume without most of it being some ML inference.
