Abstract
Motion detection devices and systems are described herein. One motion detection device includes an inertial measurement unit (IMU) configured to measure velocity, orientation, and gravitational forces of the motion detection device and a computing component. The computing component can be configured to determine spectrum parameters of a mobile vehicle associated with the motion detection device using measurements from the IMU, determine IMU orientation parameters using measurements from the IMU, and estimate motion of the mobile vehicle using the spectrum parameters, the IMU orientation parameters, measurements from the IMU, and a motion estimation function.
Claims14
A motion detection device including:
- an inertial measurement unit (IMU) configured to measure velocity, orientation, and gravitational forces of the motion detection device;
- and
- a computing component configured to:
- determine spectrum parameters of a mobile vehicle associated with the motion detection device using measurements from the IMU, wherein spectrum parameters include a cutoff frequency range of the mobile vehicle when idle and a maximum frequency of the mobile vehicle when moving along a forward direction;
- determine IMU orientation parameters using measurements from the IMU;
- estimate motion of the mobile vehicle using the spectrum parameters, the IMU orientation parameters, measurements from the IMU, and a motion estimation function;
- and
- deactivate information conveyed to a user in response to the spectrum parameters of the mobile vehicle being below the cutoff frequency range.
