<P>PROBLEM TO BE SOLVED: To provide a calibration method for a stereo camera and an information processing device that can generate correction parameters with stable precision by a simple and short-time work. <P>SOLUTION: An image of a right light emitting portion under lighting and an image of a left light emitting portion under lighting are picked up with right and left cameras respectively by using a reflector which is disposed at a position where the right and left light emitting portions under lighting can be imaged. When calibration is executed on the right and left cameras, a correction parameter for parallel shifting the position coordinate of the image picked up by the right camera to the position coordinate of the image picked up by the left camera is determined, a rotation angle of a straight line connecting the right and left light emitting portions on the basis of the image of the lit right and left light emitting portions picked up by the right camera is determined, a correction parameter for executing rotation correction on the image picked up by the right camera is determined, a rotation angle of a straight line connecting the right and left light emitting portions on the basis of the image of the lit right and left light emitting portions picked up by the left camera is determined, and a correction parameter for executing rotation correction on the image picked up by the left camera is determined. <P>COPYRIGHT: (C)2013,JPO&INPIT |
