Abstract

A stereo camera calibration method is a method for calibrating a stereo camera (30) including a first camera (1) and a second camera (2) and that captures a subject (13) through a transparent member (15). The stereo camera calibration method includes: deriving a correction parameter used to calibrate absolute positional deviation indicating deviation in coordinates of an image of the subject (13) due to the transparent member (15) in at least one of an image obtained by the first camera (1) and an image obtained by the second camera (2); capturing a calibration tool (60) with the stereo camera to obtain a first captured image with the first camera (1) and a second captured image with the second camera (2) and deriving a correction parameter used to calibrate relative positional deviation indicating deviation in disparity between the image of the subject (13) in the first captured image and the image of the subject (13) in the second captured image based on the first captured image and the second captured image; and storing the correction parameter used to calibrate the absolute positional deviation and a correction parameter based on the correction parameter used to calibrate the relative positional deviation in the stereo camera (30).
