EXTRACTION OF PLANAR SURFACE PATCHE

摘要

A planar surface patch plays a key functional role in recognizing an entity and a condition. As an important technical issue associated with the extraction side of such a planar surface patch, there still is a tradeoff between accuracy in modeling and efficiency in operation. The present invention presents a method of acquiring high accuracy in modeling from less operation and deals with a method of extracting a planar surface patch from 3D point clouds having many errors. An important contribution provided by a proposed method is as follows. 1) The strong estimation of a surface normal vector may minimize an influence on data noise. 2) As a method of identifying a planar surface patch representing a similar direction, there is a determination method of the variable size of a sliding window used in estimating the accurate location of a peak having a high density and in estimating a general vector density. The present invention shows an enhanced result in comparison typical methods through experiment results on various interior and exterior images.
