WebAt this point it is instructive to emphasize two important design ideas underlying GTSAM: The factor graph and its embodiment in code specify the joint probability distribution P ( X Z) over the entire trajectory X = { x 1, x 2, x 3 } of the robot, rather than just the last pose. This smoothing view of the world gives GTSAM its name ... WebLoop Closure Constraints¶. 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 …
