Abstract
Disclosed is a method and a system for retrieving a location of a base point of a wheeled vehicle in a local coordinate system of a tridimensional sensor mounted on the vehicle. The method includes acquiring point cloud frames while the wheeled vehicle is moving along a straight path and a curved path and a point cloud representative of a portion of the vehicle, computing a main direction vector, a main direction line and a location of an instantaneous centre of rotation of the wheeled vehicle in the local coordinate system, and retrieving the location of the base point.
