However, computing the Fisher information from a set of sparse landmarks (i. e., a point cloud), which is the most common map for visual localization, is inefficient.

We adapt a state-of-the-art visual-inertial odometry with these modifications, and experimental results show that the modified pipeline can adapt to a wide range of camera setups (e. g., 2 to 6 cameras in one experiment) without the need of sensor-specific modifications or tuning.

Visual-Inertial odometry (VIO) is the process of estimating the state (pose and velocity) of an agent (e. g., an aerial robot) by using only the input of one or more cameras plus one or more Inertial Measurement Units (IMUs) attached to it.

One of the main open challenges in visual odometry (VO) is the robustness to difficult illumination conditions or high dynamic range (HDR) environments.
