Abstract

A bird's-eye view image generating device for a vessel generates a bird's-eye view image from a view point above a vessel by projective transformation of images obtained by cameras installed on the vessel into a bird's-eye view plane. Imaging regions to be respectively imaged by the cameras are positioned such that imaging regions adjacent to each other have an overlapping region. A method of calibrating the bird's-eye view image generating device includes acquiring calibration images by imaging a calibration marker with the cameras in which the calibration marker is positioned in the overlapping region in a calibration plane, and acquiring application parameters to be applied for projective transformation of the calibration images into the calibration plane so that images of the calibration marker included in the calibration images match each other.
