LOCALISING TRANSPORTABLE APPARATUS

摘要

A method of localising transportable apparatus (100) within an environment including receiving (402) data obtained from a 2D ranging sensor device (102) of the transportable apparatus configured to collect information relating to at least a surface (120) over which the transportable apparatus is moving in an environment, and using (404) the ranging sensor device data to generate a new 3D point cloud (110) of the environment. The method further obtains (406) data representing an existing 3D point cloud (114) of at least part of the environment, and seeks to match (408) the new 3D point cloud with, or within, the existing 3D point cloud in order to localise the transportable apparatus with respect to the existing point cloud.
