Abstract
An image processing apparatus, an image processing method, and a program that permit camera calibration with high accuracy by using a known object in images captured by a plurality of imaging sections. An estimation section estimates a 3D position of a road sign included in each of images captured by a plurality of cameras with respect to each of the imaging sections. A recognition section recognizes a positional relationship between the plurality of cameras on the basis of the 3D position of the road sign with respect to each of the cameras estimated by the estimation section. The positional relationship between the plurality of cameras recognized by the recognition section is used to correct the images captured by the plurality of cameras.
