A method for registering multi-dimensional topographical data points representing a multi-dimensional object, comprises: a) receiving a plurality of points representing a plurality of overlapping frames of a surface of the multi-dimensional object; b) finding for each point in a first frame a corresponding closest point in each of a plurality of subsequent frames; c) determining a rotation and translation transformation for each of the plurality of frames so that corresponding closest points are aligned; d) determining a cost for performing each rotation and translation transformation; and e) repeating steps b) through d) for additional frames to provide an optimum transformation.

Method and system for simultaneously registering multi-dimensional topographical points

A method () for extracting a digital elevation model from a plurality of raw topographical points representing a plurality of frames representing a plurality of perspectives of a multi-dimensional object comprising a surface and above-surface obstructions, comprises steps or acts of: finding the surface () by filtering out data points produced by the above-surface obstructions to provide a plurality of surface data points representing the surface; and filtering the surface data points () with a competitive filter to provide a multi-dimensional surface shell of digital elevation model data points. The above-described method can also be carried out by a specialized or programmable information processing system () or as a set of instructions in a computer-readable medium such as a CD ROM or DVD or the like.
