Real-Time Monocular SLAM System Using an Inertial Measurement Unit to Estimate the Metric Scale and Gravity Direction
In this work a simultaneous localisation and mapping system, SLAM, has been constructed which can incorporate inertial measurement unit, IMU, data such as accelerometer and gyroscope data to estimate the metric scale and the relationship to the gravity vector of the SLAM solution. The system can perform accurate pose predictions at 100Hz based on IMU data and previous camera poses. An improved KLT
