The stereo-vision-aided Inertial Navigation System (INS) component is part of the sensor dynamics component. It combines visual-odometry measurements with inertial measurement unit (IMU) data and provides robust, low latency, real-time state estimates at a high rate. The IMU consists of three accelerometers and three gyroscopes, which measure accelerations and turn rates in all three dimensions. By fusing IMU and visual-odometry measurements, the state estimate has the same frequency as the IMU (200 Hz) and is very robust even under challenging lighting conditions and for fast motions.
