<P>PROBLEM TO BE SOLVED: To improve extraction accuracy of a three-dimensional line observed as an edge on an image from a three-dimensional shape model including a crack or overlap. <P>SOLUTION: An information processor includes: a holding unit for holding a three-dimensional model; a position and attitude input unit for inputting a position and attitude of the three-dimensional model; a selection unit for selecting line segments composing the three-dimensional model from the three-dimensional model; a projection unit for projecting, as projection line segments and projection surfaces, the line segments and surfaces composing the three-dimensional model on a two-dimensional image where respective pixels hold depth information to the three-dimensional model on the basis of the position and attitude of a target object; a deletion unit for deleting, from the selected line segments, the line segments overlapping on the two-dimensional image among the projection line segments, with one of the overlapping line segments remained; and an extraction unit for extracting, from the selected line segments after the deletion, the line segment to be an edge indicating a characteristic of the target object on the two-dimensional image on the basis of the depth information. <P>COPYRIGHT: (C)2012,JPO&INPIT |
