Hi all,
I have a system of ultra-wideband transcievers (using chips from Decawave) that allows me to de accurate indoor positioning (20mm max deviation).
I'm using this sytem to locate a kind of remote control. The thing is, I also need to know in which direction this remote control is pointing while moving it. To be more precise, I want to know what the spot is that it is pointing at using its inbuild lidar sensor. The angle therefor needs to be pretty precise, as the spot could be several meters away.
Using an IMU I believe I'll be able to accurately calculate the roll and pitch (correct me if I'm wrong), but yaw is a problem. A magenetometer on its own is not that accurate too, so I have been reading about sensor fusion algorithms, such as the madgwick one. This does give me a yaw measurement, but I'm not sure how accurate it will be. Does anybody have any experience with this?
Maybe something with directional antennas?
And, if this does not work, could you think of a way to have my beacons be part of the orientation algorithm? They are at fixed locations anyways.
I'm trying to find a way to use the signals of one or more of the to locate my remote. If needed, it is possible to add more to the beacons then just the ultra-wideband transciever.
