The MATLAB implementation of CLiFF-map a dynamic mapping algorithm

CLiFF-map stands for Circular-Linear Flow Field map. The idea behind this representation is that you can provide a set of velocity measurements (from human tracker or anemometer) and then build a map representing the motion patterns all over the environment. If you are interested in details please read my RA-L paper[1].

The repositroy can be dived into two parts.

In these two folders you will find classess and functions providing the functionalities of CLiFF-map.

• @Batch contains code necessarry to build a model of flow for one single location.
• @DynamicMap provides functionalities necessarry to build a complete map.

The repository is accompanied by two examples showing how to use CLiFF-map

• air_flow.m - This example shows how to build a sparse map out of a set of observations collected in a set of locations. In order to show the capabilities of the method I have used a wind measurements obtained by Yuta Wada, Marco Trincavelli, Yuichiro Fukazawa and Hiroshi Ishida[2].
• people_flow.m - This example shows ho to build CLiFF-map if the observations are randomy distibuted all over the map and it is necessarry to discretise them so they will fit a refualr grid. This example uses data set generated with ped-sim (https://github.com/srl-freiburg/pedsim_ros).

Soon!

Currently I am organising my research code and preparing it for release. I will try to do it as fast as possible.
