Abstract
Visual simultaneous localization and mapping (V-SLAM) technique plays a key role in perception of autonomous mobile robots, augmented/mixed/virtual reality, as well as high-level geometric perception and spatial AI applications. This paper gives a very concise survey about the back-end module of a V-SLAM system, which is essentially a nonlinear least square (NLLS) problem. This problem is traditionally solved by a local iterative linearized optimization algorithm with a good initial guess, such as the Gauss-Newton algorithm. Due to the nonconvexity of the NLLS problem, these local iterative solvers cannot provide any guarantee on the global minimum convergence, which is crucial for active SLAM systems and life-critical applications, such as autonomous driving. Therefore, new trend about robust global optimization algorithms for the pose graph are introduced, which adopt duality theory, convex relaxation, and robust cost functions to provide a certified global optimal solution.
