Application: icp-slam

1. Description

icp-slam is a front-end application to the MRPT C++ library class mrpt::slam::CMetricMapBuilderICP. This SLAM algorithm builds a map incrementally by aligning new range scans to either a point point or an occupancy grid map using the ICP algorithm. The ICP implementation itself can be found in the class mrpt::slam::CICP. See this tutorial describing the algorithm.

 

2. Demo

To run one of the demos included in MRPT, execute:

or to use that same configuration with your own data set:

Check out the comments in the configuration files provided in MRPT/share/mrpt/config_files/icp-slam/ for further reference. Note that both ICP can be configured to use either a points or occupancy grid map to perform the scan alignment. And even using one of them, the other map type can be also built simultaneously.

NOTE: The rawlog “2007-05MAY-17_SENA_Floor2.3_1laser.rawlog” used in the demo video below is not included by default in the MRPT package, please grab it separately from the collection of datasets..
