For those interested in filmmaking, I'm looking at FreeIMU or SpacePoint Scout as a relative location and orientation tracking kit. Links below. http://www.pnicorp.com/products/spacepoint-scout https://viacopter.eu/multirotor-shop/sensors/freeimu-0-4-3-multicopter-store The idea behind it, I think, would be to attach the kit to the camera within a greenscreen room, then to move around in that room and record the data along side the film. That data would then be shifted into a 3d program to render out the background within say, a star ship bridge, and match the two together. Wondering if people have ever come across or used this kit in the past, or have any opinions on what I'd like to try? It doesn't seem to pricy either. Which is good! Cheers, J.
