Research on Landmarks of SLAM Based on Square Root Cubature Kalman Filter

open access: yesJournal of Physics: Conference Series, 2018
Under the large noise, the system's observability is weak, which leads to the instability of the filtering algorithm and the slow convergence speed. The algorithm of simultaneous localization and mapping based on the square-root Cubature Kalman filter (SRCKF) with Spherical Simplex(SS) was proposed in this paper.
