Information processing apparatus, information processing method, and program

Abstract

There is proposed a new and improved information processing apparatus, an information processing method, and a program capable of more simply detecting whether or not a deviation related to a camera parameter has occurred in a plurality of cameras. The information processing apparatus includes a calculator that calculates a three-dimensional position of a feature point on the basis of each of images obtained by imaging a subject at a first timing by a plurality of cameras and an external parameter of the plurality of cameras, the feature point being included in each of the images, a first estimator that estimates a first external parameter on the basis of one image included in the images obtained by imaging the subject at a second timing by the plurality of cameras and the three-dimensional position of the feature point, the first external parameter being an external parameter of a camera that has captured the one image among the plurality of cameras at the second timing, a second estimator that estimates a second external parameter that is an external parameter of any one camera of the plurality of cameras at the first timing on the basis of the first external parameter estimated by the first estimator, and a determiner that determines whether or not a deviation related to the external parameter has occurred in the plurality of cameras on the basis of the second external parameter of any one camera of the plurality of cameras and a previous external parameter of the any one camera, the second external parameter having been estimated by the second estimator.
