incremental SAM

iSAM, or Incremental Smoothing and Mapping, is a novel incremental optimization technique for mapping and localization in robotics. In its latest incarnation, iSAM2 , we represent what we know about the robot’s environment as a large tree data structure called the Bayes tree, which we iteratively update as more measurements come in via the robot’s sensors. Please refer to the publications below, but you can also watch a movie here.
