Patent ID: 8718393

Claim:
An urban scenes reconstruction method, comprising: acquiring a 3D scan of a three-dimensional subject; extracting a plurality of planar components from the 3D scan; extracting an edge segment of each planar component; establishing a plurality of three-dimensional subject blocks via data fitting and contextual term based on the edge segment; selectively grouping a portion of the plurality of three-dimensional subject blocks based on one of a logical attribute or a physical attribute, to form a compound three-dimensional subject block where the grouped portion of the plurality of three-dimensional subject blocks are manipulated and transformed as one; dragging-and-dropping one of the three-dimensional subject blocks and establishing an interval length between that one three-dimensional subject block and an adjacent three-dimensional subject block in one of two orthogonal directions based on regularity constraints, determining an interval length of the one three-dimensional subject block and an adjacent three-dimensional subject block, and predicting a position of another three-dimensional subject block based on a difference between the established interval length and the determined interval length; finding an optimal sizes and positions of further of the plurality of three-dimensional subject blocks via the predicted position thereof; and copying a further three-dimensional subject block to a next of the positions found.
