Abstract

There is provided an image processing apparatus including a plurality of imaging units included in a stereo camera, the plurality of imaging units being configured to image a first chart pattern including a pattern that is a plurality of feature points and a mirror surface, and a correction parameter calculation unit configured to calculate a correction parameter that corrects a gap of the plurality of imaging units, based on the pattern included in the first chart pattern imaged by the plurality of imaging units and a pattern mirrored in the mirror surface.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Japanese Priority Patent Application JP2012-243180 filed on November 2, 2012, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to an image processing device and method, an image processing system, and a program. Specifically, the present disclosure relates to an image processing device and method, an image processing system, and a program that can easily realize calibration of a plurality of cameras that capture stereoscopic images with high accuracy in a small space. Background technique [0004] In general, techniques that can capture three-dimensional images by using a plurality of cameras are widespread. [0005] As a method of generating a three-dimensional image, there is known a common method of forming a stereo camera by setting two cameras of different viewpoints, calculating parallax based on ster...
