An information processing apparatus configured to estimate a position and orientation of a measuring object using an imaging apparatus includes a three-dimensional shape model of the measuring object, an image input unit configured to acquire a captured image of the measuring object, an approximate position and orientation input unit configured to input a relative approximate position and orientation between the imaging apparatus and the measuring object, a first position and orientation updating unit configured to update the approximate position and orientation by matching the three-dimensional shape model to the image, , a position and orientation difference information input unit configured to calculate and acquire a position and orientation difference amount of the imaging apparatus relative to the measuring object, and a second position and orientation updating unit configured to update the approximate position and orientation based on the position and orientation difference amount, using the approximate position and orientation. |
