Abstract
An information processing apparatus includes a captured image acquisition unit configured to acquire an image captured by imaging a device that includes a plurality of markers, and an estimation processing unit configured to estimate position information and posture information of the device on the basis of a marker image coordinate in the captured image. The estimation processing unit includes an extraction unit configured to extract N marker image coordinates in the captured image, N being an integer equal to or greater than three, and a position and posture derivation unit configured to derive the position information and the posture information of the device from the extracted N marker image coordinates and three-dimensional coordinates of N markers in a three-dimensional model of the device. The extraction unit extracts, where selected N+A marker image coordinates have a predetermined positional relation, N marker image coordinates from among the N+A marker image coordinates, A being an integer equal to or greater than one.
