Title:
INFORMATION PROCESSING APPARATUS, CALIBRATION METHOD, AND CALIBRATION PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2016/194078
Kind Code:
A1
Abstract:
A storage unit (107) stores, as a reference coordinate correspondence relationship, a correspondence relationship between the physical coordinates in a movement space in which a moving body moves and the pixel coordinates in a captured image that is obtained by an imager apparatus, which is placed at a predetermined placement position and the imaging direction of which is fixed toward the movement space, imaging the movement space. A feature point detection unit (104) extracts, as a feature point coordinate correspondence relationship, a correspondence relationship between the pixel coordinates of a feature point in the moving body in a captured image obtained by the imager apparatus imaging the moving body when the moving body stops in the movement space, and the physical coordinates of the feature point when the imager apparatus images the moving body. A correction unit (106) corrects the reference coordinate correspondence relationship by use of the feature point coordinate correspondence relationship extracted by the feature point detection unit (104).
