Here's some background on the amazing Intel drone displays at the Olympics.
Wired article here
Future headline: "10,000 drones fall from sky when power to network servers fail." Intel seems to be more focused on marketing rather than innovation. It's hard to respect an organization that has so many resources when they use digital "smoke and mirrors" to give the illusion of advanced capabilities. Much more impressed by the DIY and open-source communities exploration into true autonomous based systems. 3D light brights in the sky are so 2013. :)
Sadly, this article doesn't tell us anything we don't already know and haven't already known for several years.
Are they using RTK GPS or some other positioning technology?What's really interesting is how the algorithms are able to generate motion paths such that one vehicle won't run into another and not only that but the fact that they are able to handle the rotor wash and turbulence generated by a vehicle's nearest neighbors.
@Nikola the pathing is derived from whatever 3D modeling environment they're using. You too can build a 3D light bright with an open source 3D modeling tool such as Blender. Check out particle paths/meshes. Once you have your model and simulation, assign your drone pixel to a particle and transmit it's 3D position delta during playback. Hopefully, each UAV is tolerant to network interruption for some small period of time, not sure? The driving force in this display is the heavy handed networking. Not sure if you read the article and or watched the video, but the aircraft are not very tolerant to weather conditions. That being said, Intel has executed the equivalent of extreme eating in the entertainment drone world; why eat one hot dog when you can eat 350? Wonder if Intel has calculated the costs in time/energy/dollars per pixel flown to create, roughly, a 10 x 10 x 10 volumetric display? Probably the most exceptional aspect of what they are doing are logistics based around resource management and allocation for a given event. Measuring the health/fitness of an aircraft to perform a piece of a larger task and creating a system around managing that is more of a story, in my opinion, than the 3D display. Anyone who has built these kinds of systems know that the "magic" is in the doing/process, not really the result. Sure glad I'm not the poor slob in charge of the (1200 x N) battery management for the project(battery charging hell, so to speak).
Notice that the show was prerecorded (from article linked above) : "Also like the Super Bowl, the opening ceremony production you'll see on your TV - or streaming device - was prerecorded. That's less of a cheat than an insurance policy; tiny drones can only handle so much abuse, and Pyeongchang is a cold and windy city."
Same for the Super Bowl Lady Gaga Drones show : "How on earth did Intel get away with it? The short answer is, it taped the show earlier this week." ( https://www.wired.com/2017/02/lady-gaga-halftime-show-drones/?mbid=... )
So it's always prerecorded, and honestly it looks more like computer graphics than real drones :
This Chinese drone shows seems much more realistic, especially regarding the speed at which drones are moving. And also their use of many colors, which seems logical as they can apparently produce billions of colours :
