Abstract: [Object] To perform map synchronization in a manner more intuitive for a user.
[Solving Means] An information processing apparatus includes: a map generating unit that generates a first map and estimates a chronological self-position in the first map, thereby generating the first three-dimensional trajectory; a slave trajectory acquiring unit that acquires the second three-dimensional trajectory generated by estimating the chronological self-position in a second map generated in the map generating unit of a slave apparatus, the slave apparatus being another information processing apparatus that functions as a slave; an observed trajectory generating unit that generates an observed two-dimensional trajectory, the observed two-dimensional trajectory being a two-dimensional trajectory indicating a chronological position of the slave apparatus in a captured image obtained by a camera imaging the slave apparatus; and a transformation parameter calculating unit that calculates a transformation parameter for generating a synchronized map obtained by synchronizing the first map with the second map on the basis of the first three-dimensional trajectory, the second three-dimensional trajectory, and the observed two-dimensional trajectory.

Abstract: To more easily estimate a position and a posture of an imaging camera.
An information processing apparatus including: a position estimation unit configured to estimate a position and a posture of an imaging camera configured to image an image displayed on a display device as a background by using a plurality of markers existing on a display surface of the display device; and a marker control unit configured to control display or non-display of each of the markers on the basis of a viewing angle of the imaging camera determined from the position and the posture of the imaging camera.
