Abstract: Provided is an information processing apparatus including a captured image acquisition unit that acquires an image captured of a device including markers, an extraction unit that extracts a marker image coordinate in the captured image, a position and posture derivation unit that derives position information and posture information of the device from the extracted marker image coordinate and a three-dimensional coordinate of a candidate marker in a three-dimensional model of the device by performing a predetermined calculation, and a sensor data acquisition unit. The position and posture derivation unit places the three-dimensional model in a virtual three-dimensional space, and discards or selects the candidate marker to be used for the calculation, on the basis of a difference between an orientation of a surface on which the candidate marker is provided among surfaces of the three-dimensional model and an orientation of a screen surface of the captured image.

Abstract: A first extraction processing unit 234 extracts a plurality of sets of first connected components of eight neighboring pixels from a photographed image. A second extraction processing unit 236 extracts a plurality of sets of second connected components from the first connected components extracted by the first extraction processing unit 234. A representative coordinate derivation unit 238 derives representative coordinates of a marker image on the basis of the pixels of the first connected components extracted by the first extraction processing unit 234 and/or the pixels of the second connected components extracted by the second extraction processing unit 236.
