gtsam_points

This is a collection of GTSAM factors and optimizers for range-based SLAM.

Tested on Ubuntu 22.04 / 24.04 and CUDA 12.2, and NVIDIA Jetson Orin with GTSAM 4.2a9.

Factors

Scan Matching Factors

  • IntegratedICPFactor & IntegratedPointToPlaneICPFactor
    The conventional point-to-point and point-to-plane ICP [1].
  • IntegratedGICPFactor
    Generalized ICP based on the distribution-to-distribution distance [2].
  • IntegratedVGICPFactor
    GICP with voxel-based data association and multi-distribution-correspondence [3][4].
  • IntegratedVGICPFactorGPU
    GPU implementation of VGICP [3][4].
    To enable this factor, set -DBUILD_WITH_CUDA=ON.
  • IntegratedLOAMFactor
    Matching cost factor based on the combination of point-to-plane and point-to-edge distances [5][6].

Colored Scan Matching Factors

  • IntegratedColorConsistencyFactor
    Photometric ICP error [7].
  • IntegratedColoredGICPFactor
    Photometric ICP error + GICP geometric error [2][7].

Continuous-time ICP Factors

  • IntegratedCT_ICPFactor
    Continuous Time ICP Factor [8].
  • IntegratedCT_GICPFactor
    Continuous Time ICP with GICP's D2D matching cost [2][8].

Bundle Adjustment Factors

  • PlaneEVMFactor and EdgeEVMFactor
    Bundle adjustment factor based on Eigenvalue minimization [9].
  • LsqBundleAdjustmentFactor
    Bundle adjustment factor based on EVM and EF optimal condition satisfaction [10].

Optimizers for GPU Factors

All the following optimizers were derived from the implementations in GTSAM.

  • LevenbergMarquardtOptimizerExt
  • ISAM2Ext
  • IncrementalFixedLagSmootherExt

Nearest Neighbor Search

  • KdTree KdTree with parallel tree construction. Derived from nanoflann.
  • IncrementalVoxelMap Incremental voxel-based nearest neighbor search (iVox) [11].
  • IncrementalCovarianceVoxelMap Incremental voxelmap with online normal and covariance estimation.

Continuous-Time Trajectory (Under development)

  • B-Spline Cubic B-Spline-based interpolation and linear acceleration and angular velocity expressions [12].
  • ContinuousTrajectory Cubic B-Spline-based continuous trajectory representation for offline batch optimization.
