Read pose graph containing loop closures and odometry to compute correspondences. Uses aggressive pruning – reject any suspicious pair.

Parameters:

  • fnames_processed (list[str]) – List of filenames (str) for pre-processed pointcloud fragments.

  • fragment_pose_graph (open3d.pipelines.registration.PoseGraph) – PoseGraph for pointcloud fragments

  • (open3d.t.pipelines.slac.slac_optimizer_params (params) – 0”), slac_folder=””)): slac_optimizer_params Parameters to tune in optimization.

  • optional – 0”), slac_folder=””)): slac_optimizer_params Parameters to tune in optimization.

  • default=SLACOptimizerParams(max_iterations=5 – 0”), slac_folder=””)): slac_optimizer_params Parameters to tune in optimization.
