Abstract: PURPOSE: An extracting apparatus for structure boundary and a method thereof are provided to reduce process times and costs, since load applied on a system is minimized by a process of extracting the outline of structure. CONSTITUTION: An extracting apparatus for structure boundary comprises a scanner unit(11), a first extracting unit(14), a second extracting unit(16), a third extracting unit(17), and a data reduction unit(15). The scanner unit transmits laser beam based on ground radar. The scanner unit receives the laser beam reflected from a structure(1). The first extracting unit extracts the candidate point of the structure using translation distance mean value and density value according to the distribution of point group data. The second extracting unit extracts the candidate point of the outline of the structure from the extracted candidate point of the structure based on the dot density. The third extracting unit extracts the actual outline from the extracted outline candidate point.
