    Simulate a robot traversing down a 1-dimension hallway with noise odometry readings and noise range readings of the end of the hallway. By fusing the noisy odometry and sensor readings this example demonstrates how to compute the maximum likelihood estimate (MLE) of the robot's pose at each timestamp. https://github.com/ceres-solver/ceres-solver/blob/master/examples/robot_pose_mle.cc

  8. ceres08_PoseGraph3D
    An example formulate the pose graph based SLAM problem in 3-Dimensions with relative pose constraints.

  11. ceres11_Pose2DEstimation
    Consider we have two matched 2D points pair $\mathbf{p}A \leftrightarrow \mathbf{p}B$, and want to estimate the 2D transformation $\mathbf{R} \in SO(2), \mathbf{p} \in \mathbb{R}^2$ between the points, i.e., $$ \mathbf{e} = \sum{n=0}^{N} (\mathbf{R} \mathbf{p}{A,n}+ \mathbf{p} - \mathbf{p}_{B,n}) $$ The code using two method to optimize this problem,
    • Analytical Jacobian with pose manifold (R, p)
    • ceres auto Jacobian with pose manifold (R, p)
    • ceres auto Jacobian with angle manifold (theta, p).
  12. ceres12_Pose3DEstimation
    Similar to ceres11_Pose2DEstimation but with 3D transformation. Consider we have two matched 3D points pair $\mathbf{p}A \leftrightarrow \mathbf{p}B$, and want to estimate the 3D transformation $\mathbf{R} \in SO(3), \mathbf{p} \in \mathbb{R}^3$ between the points, i.e., $$ \mathbf{e} = \sum{n=0}^{N} (\mathbf{R} \mathbf{p}{A,n}+ \mathbf{p} - \mathbf{p}_{B,n}) $$ The problem is also named after ICP, the code using two method to optimize this problem,
    • Analytical Jacobian with pose manifold (R, p)
    • ceres auto Jacobian with pose manifold (R, p)

Note

  1. Migrate code from ceres 1.x to ceres 2.x, the main difference is using Manifold instead of LocalParameterization
    • GlobalSize => AmbientSize
    • LocalSize => TangentSize
    • ComputeJacobian => PlusJacobian
    • add Minus and MinusJacobian, but these two method don't used currently, could just return true; right now(see github issue)
