Patent ID: 6873713

Claim:
An image processing apparatus comprising: a first image sensing means for sensing an object image in a first direction to extract X 1 number of feature points from the object image; a second image sensing means for sensing the object image in a second direction to extract X 2 number of feature points from the object image; and a normalization means for extracting a plurality of feature points from first object image data obtained during sensing by the first image sensing means, checking whether the number of the extracted plurality of feature points corresponds to a preset X 1 number, extracting a plurality of feature points from second object image data obtained during sensing by the second image sensing means, checking whether the number of the extracted plurality of feature points corresponds to a preset X 2 number, setting a first feature region on the first object image data by a first method based on the X 1 number of feature points, setting a second feature region on the second object image data by a second method based on the X 2 number of feature points, segmenting the first feature region into a plurality of regions, computing predetermined information in each segmented region, computing a first feature pattern based on the computed predetermined information, segmenting the second feature region into a plurality of regions, computing predetermined information in each segmented region, and computing a second feature pattern based on the computed predetermined information.
