PROBLEM TO BE SOLVED: To provide an image processing device capable of securing camera calibration accuracy even if an installable range of a calibration marker is limited.SOLUTION: An image processing device 10 includes: an image acquisition unit 1 for acquiring an image in which the calibration marker is imaged; an edge detection unit 2 for detecting the edge of the marker in the image; a polygon generation unit 3 for estimating a plurality of straight lines on the basis of the edge, and generating a virtual polygon region surrounded by the plurality of straight lines in a region including a region in the image other than the area where the marker is installed; and a camera parameter calculation unit 4 for calculating a camera parameter on the basis of the feature amount of the virtual polygon region in the image and the feature amount of the virtual polygon region in the real space.
