An inertial sensor is used to compensate the motion endorsed by the indoor mapping system, whether it is a camera or a LiDAR.

It can be also used to aid the SLAM computation, helping maintaining position or heading between two SLAM information.

Tips

Indoor positioning relies on several technologies such as LiDAR and inertial sensors with the SLAM computation for example.

In real-time, the SBG inertial sensor delivers orientation data that is used to correct the equipment attitude and helps the SLAM computation. For example, between two SLAM information, the INS keeps the heading robust.

The Inertial Measurement Unit (IMU) outputs gyroscopes, accelerometers, and magnetometers raw data. The Attitude and Heading Reference System (AHRS) embeds an Extended Kalman Filter (EKF) to deliver orientation data, and the Inertial Navigation System (INS) additionally embeds a GNSS receiver for a filtered position in real-time.
