Patent ID: 8396255

Claim:
Computer arrangement, comprising: a memory; and a processor, arranged to communicate with the memory, the memory storing a computer program including instructions and data that can be run by the processor, and storing a set of laser scan samples including a sub-set of laser scan samples relating to a facade of a building and storing location data for each of the laser scan samples, said memory also storing a picture of the facade including location data as to pixels of the picture, the picture including data as to a wall of the facade and data as to texture elements in the wall, said stored computer program being executed on said processor arranged to: retrieve from memory a plurality of series of consecutive laser samples, each series of laser samples lying in a separate plane substantially perpendicular to the earth, to produce a distance histogram of laser scan samples in each separate plane, and to identify a peak in each of the distance histograms in proximity to where the facade is expected to be located, and to select said sub-set of laser scan samples as being laser scan samples on the peak and to automatically relate the sub-set of laser scan samples to the facade; and automatically identify the wall and the texture elements in the picture using the laser scan samples.
