The invention belongs to the field of
data association, and particularly relates to a line
feature data association method of a
robot based on improved
ant colony optimization. The method comprises the following steps: constructing a
global coordinate system and a local coordinate
system, and setting a sensor working mode; establishing a line feature observation model; extracting environmental line features using an improved segmentation-aggregation method; designing a line
feature data association method combining an improved ICNN method and an improved
ant colony optimization method; and inputting the environmental line feature information and the
mobile robot pose information obtained by the sensor into a line
feature data association method based on improved
ant colony optimization, carrying out
data association to obtain an association pair set, and updating the map
feature set. Firstly, environment line characteristics are extracted based on
laser sensor data, then an improved ICNN
algorithm and an improved
ant colony optimization
algorithm are combined, the correlation accuracy of a
data correlation algorithm is improved, and an accurate environment map is obtained.
