The main idea is embed high-resolution images into the view of 360 sphere. That is a slick demo by Ricoh, but you can do similar things cheaply with a normal camera and your own software or inexpensive software like pano2vr or krpano.
See this.
StructionSite might be able to use the same technique with your own app for shots that require more detail.
There’s really so much potential with 360 images right now that there’s no shortage of million dollar ideas. Just have to build um. 
Would love to see you guys hit the jackpot with software to help construction builders.
