USAGE EXAMPLES

graph-slam --2d --dijkstra --view -i in.graph

Visualization of a 2D (or 3D) graph file

graph-slam --2d [or --3d] --view -i in.graph

Levenberg-Marquartd optimization of a 3D graph and visualize result

graph-slam --3d --levmarq --view -i in.graph

DESCRIPTION

graph-slam is a command-line application to visualize pose constraint graphs and execute Graph-SLAM methods on them.

These are the supported arguments and operations:

   --info
     Op: Loads the graph and displays statistics and information on it.
   --dijkstra
     Op: Executes CNetworkOfPoses::dijkstra_nodes_estimate() to estimate
     the global pose of nodes from a Dijkstra tree and the edge relative
     poses.
     Can be used together with: --view, --output
   --levmarq
     Op: Optimizes the graph with sparse Levenberg-Marquartd using global
     coordinates (via mrpt::graphslam::optimize_graph_spa_levmarq).
     Can be used together with: --view, --output, --max-iters, --no-span,
     --initial-lambda
   --no-span
     Don't use dijkstra initial spanning tree guess (optional)
   --initial-lambda <val>
     Initial lambda parameter (optional, lev-marq)
   --max-iters <N>
     Maximum number of iterations (optional)
   -q,  --quiet
     Terse output
   --view
     Op: Visualize the graph in a 3D view. If used alone, represent VERTEX2
     or VERTEX3 poses directly as stored in the input file. If used
     together with another operation, the final obtained graph after the
     operation will be shown, not the input original one.
   --3d
     Use 3D poses (Must use exactly one of --2d and --3d)
   --2d
     Use 2D poses (Must use exactly one of --2d and --3d)
   -o <result.graph>,  --output <result.graph>
     Output file (optional) (*.graph,*.graphbin)
   -i <test.graph>,  --input <test.graph>
     (required)  Input file (required) (*.graph,*.graphbin)
   --,  --ignore_rest
     Ignores the rest of the labeled arguments following this flag.
   --version
     Displays version information and exits.
   -h,  --help
     Displays usage information and exits.
