Dynamic 3D Mapping - Visual Estimation of Independent Motions for 3D Structures in Dynamic Environments

Abstract

This paper describes an approach to consistently model and characterize potential object candidates presented in non-static scenes. With a stereo camera rig we recollect and collate range data from different views around a scene. Three principal procedures support our method: i) the segmentation of the captured range images into 3D clusters or blobs, by which we obtain a first gross impression of the spatial structure of the scene, ii) the maintenance and reliability of the map, which is obtained through the fusion of the captured and mapped data to which we assign a degree of existence (confidence value), iii) the visual motion estimation of potential object candidates, through the combination of the texture and 3D-spatial information, allows not only to update the state of the actors and perceive their changes in a scene, but also to maintain and refine their individual 3D structures over time. The validation of the visual motion estimation is supported by a dual-layered 3Dmapping framework in which we are able to store the geometric and abstract properties of the mapped entities or blobs, and determine which entities were moved in order to update the map to the actual scene state.
