Patent ID: 8917912

Claim:
An object identification system comprising: a first pattern data generating part configured to divide a first angle section corresponding to images of previewed real objects into a first angle gap which is uniform with respect to a position where the real objects are previewed, to calculate boundaries between the real objects from images of the real objects, and to generate a first pattern data configured by set of first indicators which corresponds to each angles of the first angle section divided into the first angle gap and which varies every boundary between the calculated real objects; a map data storing part configured to store a map data comprising virtual objects having a second indicator and an outline data as attribute value; a second pattern data generating part configured to divide the map data into a second angle gap which is uniform with respect to a position where the real objects are previewed, to extract a virtual object having an outline firstly meet with a radiating line corresponding to each map angle of the divided into the second angle gap, and to generate a second pattern data configured by set of second indicators corresponding to each map angle; and an object identifying part configured to compare with a first arrangement pattern of first indicators arranged on the first angle section and a second arrangement pattern of second indicators arranged on a second angle section substantially equal to the first angle section, to match the first indicators into second indicators having a repeat ratio substantially equal to a repeat ratio of the first indicators in an angle section, to match a real object disposed on an angle corresponding to the matched first indicator into a virtual object having a second indicator matched with the first indicator as an attribute value, and to extract virtual objects matched with each of the previewed real objects, wherein the first angle gap is one of n times (‘n’ is an integer) and 1/n times of the second angle gap.
