MSCKF maintains several previous camera poses in the state vector, and uses visual measurements of the same feature across multiple camera views to form multi-constraint update. This is an implementation of a Multi-State Constraint Kalman Filter (MSCKF) which leverages inertial and visual feature information. These visual feature tracks are fused leveraging the Multi-State Constraint Kalman Filter (MSCKF) sliding window formulation which allows for 3D features to update the state estimate without directly estimating the feature states in the filter.
