According to the multi-source
information fusion robot positioning method and
system for the unstructured environment provided by the invention, fusion
processing is carried out on multi-source
information data such as
laser point cloud, environment image information and acceleration which are acquired in real time, so that the multi-source
information fusion robot positioning method and
system for the unstructured environment can be realized in a
severe weather state and a dynamic unstructured environment. Carrying out high-robustness real-time positioning under the condition of violent illumination change; in a geometrically degraded roadway area, registration positioning of
laser point cloud emission fails due to lack of enough external characteristics, and at the moment, the
visual positioning module can still work normally and complete
robot repositioning by detecting matched image information; in an environment lacking enough illumination, the
laser point cloud and acceleration information can still provide enough positioning fusion
data input for the computing unit.
