A METHOD AND ARRANGEMENT FOR PROVIDING A 3D MODEL

摘要

The present invention relates to a method and an arrangement for providing a 3D model of an environment. The method comprises the step of forming a mesh modelling the environment in three dimensions, said mesh comprising nodes interconnected by edges and having surfaces boarded by the edges, wherein each node is associated to a 3D coordinate in a geographical coordinate system, determining for a plurality of the nodes and/or surfaces and/or edges in the mesh a mesh uncertainty and associating the determined mesh uncertainty to the corresponding node and/or surface and/or edge.

1. A method for providing a 3D model of an environment comprising the step of
forming a mesh modelling the environment in three dimensions, said mesh comprising nodes interconnected by edges and having surfaces boarded by the edges, wherein the step of determining for each of a plurality of the nodes and/or surfaces and/or edges in the mesh a mesh uncertainty representing a measure of the reliability of the mesh modelling the environment in that node and/or surface and/or edge and associating the determined mesh uncertainty to the corresponding node and/or surface and/or edge, wherein each node of the mesh is associated to a 3D coordinate in a geographical coordinate system and wherein the mesh uncertainty represents a measure of the reliability of 3D coordinate in the geographical coordinate system.
