IMU inertial system OptoWOM-II

AHRSMEMSmotion control

The Inertial Labs Optically enhanced Weapon Orientation Module – OptoWOM-II, is Inertial Labs’ second generation of its Optically Enhanced Weapon Orientation Module. OptoWOM-II combines technologies of inertial sensors with optical image tracking resulting in a robust and reliable 3DOF orientation module capable of operation in virtually any environment. With the addition of optical image tracking the system is now able to mount directly to a device under measure and operated immediately without any magnetic calibration whatsoever. During operation, the device’s magnetometer calibrations are able to be derived on-the-fly allowing for the device to operate with both optical and magnetic heading determination as a result of normal operation of the device. OptoWOM-II optical tracking works through the use of reference images. A reference image is literally a picture of the horizon in a given direction. Within the reference image the system identifies a constellation of identifiable features. Then, from any subsequent image collected by the camera, heading is determined by comparing those images back to the most appropriate reference.
