The simplest instantiation of a SLAM problem is PoseSLAM, which avoids building an explicit map of the environment.The goal of SLAM is to simultaneously localize a robot and map the environment given incoming sensor measurements (Durrant-Whyte and Bailey, 2006).Besides wheel odometry, one of the … WebGTSAM is a library of C++ classes that implement smoothing and mapping (SAM) in robotics and vision, using factor graphs and Bayes networks as the underlying computing paradigm rather than sparse matrices. - gtsam/SFMExampleExpressions.cpp at develop · … shoe station logo
