Abstract
An apparatus includes a capturing unit that captures a target object and generates a range image representing distance information, a general estimation unit that analyzes the range image and estimates a general position and orientation of the target object, and a determination unit that determines a priority order of a plurality of identification units, based on the estimated general position and orientation. In addition, a setting unit sets a search window indicating a range for detailed estimation of position and orientation of the range image based on a preregistered general size of the target object, a calculation unit calculates a difference between a first distance value of a first pixel in the range image and a second distance value of a second pixel which is next to the first pixel in the range image, and an updating unit updates the search window based on the calculated difference. A detailed estimation unit estimates a detailed position and orientation of the target object, using the plurality of identification units in the determined priority order within the range of the search window.
