I asked iPi about the quality of the RealSense sensor already and was told it's quality isn't optimal for iPi Tracking, so I doubt would be any different if trying a real time tracking solution, at this point in time anyway, actually recommended the Orbbec Astra Pro, as you can still connect multiple sensors to one PC, but for quality of noise output compared to the Kinect v2, I am not sure, hopefully iPi will do videos for each cam as well.
I don't see the need in my case to upgrade any peripherals either, I am sticking with my PS Eyes in v4 as well, but may test a Kinect "real time" tracking option for my own curiosity :)
BUT... If I had the space to fully justify an upgrade, I think the Logitech Brio would be an optimal indoor camera for use with iPi, but @ $199, I would need the increased studio capture area to justify the purchase, it has 1080p @ 60fps / 720p @ 90fps and RightLight tech that would be very handy for iPi recording and a much wider FOV than any other HD cam in it's class, but I don't know much about the action cams, the cut rate ones available, although I don't think they have the same tech for best video output with iPi, I could be wrong on that, but I do see that the new high end action cams have voice control record start, wonder if it works with multiple cam set ups to eliminate a simultaneous start switch? There are some that are Wifi, so wondering if iPi Recorder v4 will support that when using multiple cams.
Link to many HD Action Cam models:
https://www.gearbest.com/4k-60fps-action-cam-_gear/There are several "real time" Depth Sensor SDKs out there now, but the tracking quality to me is far from optimal, and none that can use multiple sensors, but cool they can stream into other 3D packages in real time, but not a significant task for me.
I am sure they will do their best, just from the release of iPi v3 to where it is now has made leaps in improvement in tracking to me personally with my set up.
I am also wondering, with the new build video task, if you can export the individual 1080p RGB footage from multiple depth sensors, (wearing the correct colored clothing), and use those videos to track inside iPi Studio 4... that is if a user already has at least 3 Kinect v2, or other sensors, I am guessing it would take at least 3 sensors video views to track optimally, but I don't know, maybe only 2 would track ok if set up in a 90 degree set up, but still only 1080p @ 30fps video output.
