<P>PROBLEM TO BE SOLVED: To make reference and recognition in high accuracy and in a quick manner by eliminating, from a three-dimensional dictionary data, data associated with an area of an object, the area not being measured. <P>SOLUTION: A three-dimensional object position detecting device estimates a general posture (S3) and generates "three-dimensional dictionary data P' after general conversion" by performing posture conversion of three-dimensional dictionary data according to the general posture (S4). Next, the device projects the point group of "three-dimensional dictionary data P' after general conversion" on a virtual plane perpendicular to the distance direction from a measuring device to an object (S5). Then, the detecting device eliminates, from the three-dimensional dictionary data, data associated with an area, of an object, that is not measured by dividing the virtual plane into a plurality of rectangular areas, selecting only a point nearest to the measuring device from the plurality of (projected) points belonging to each divided rectangular area, and re-generating three-dimensional dictionary data formed of only the selected points(S6). <P>COPYRIGHT: (C)2013,JPO&INPIT |
