Solution
Using UWB (Ultra Wide Band) ultra-wideband technology, the relative distance and angle between the "receiving end module" and the "pointing end module" can be accurately obtained. The "pointing end module" is integrated with IMU inertial navigation. The module fuses the read inertial navigation measurement data with the UWB measurement data, and finally obtains the position and attitude information of the "pointing end module" relative to the "receiving end module" .
This set of modules is divided into two parts: the "receiving end" and the "pointing end". The "receiving end" is fixed on a device pointing to the display surface, such as a smart TV; the "pointing end" is integrated into a handheld operating device, such as a remote control;
The "receiving end module" integrates multi-antenna UWB, Bluetooth Soc, etc., and can output the three-dimensional position relationship (distance and angle) of the "pointing end module" relative to this module;
The "pointing end module" integrates IMU inertial navigation, multi-antenna UWB, Bluetooth SoC, etc., and can output the attitude and pointing plane projection point of the "pointing end module" relative to the "receiving end module";
