Abstract
A method for spatial mapping of an environment comprises receiving a plurality of depth images of an environment via an imaging device, each depth image associated with a local coordinate system. For each local coordinate system, each associated depth image is fused to generate a local volume. Each local volume is then fused into a global volume having a global coordinate system, and then a surface mesh is extracted for the global volume. One or more regions of inconsistency within the global volume are determined and localized to one or more erroneous local volumes. The one or more erroneous local volumes are unfused from the global volume, and then non-erroneous local volumes are re-fused into a corrected global volume. By using a two-step fusion process, regions of inconsistency, such as mirror reflections, may be corrected without requiring reconstruction of the entire global volume.
