The focus of the work is on real-time operation with many landmarks, which is espe-cially difﬁcult with the EKF due to its computational com-plexity. Combined Topics. Solving a graph-based SLAM problem involves to construct a graph whose nodes represent robot poses or landmarks and in which an edge between two nodes encodes a sensor measurement that con-strains the connected. However, this algorithm, which involves computing the square root of the state covariance matrix at each time step, has computational complexity cubic in the number of landmarks, and thus is not suitable for real-time operation in large environments. Open3D is an open-source library that supports rapid development of software that deals with 3D data.
