Abstract: An in-vehicle camera calibrator is provided. The in-vehicle camera calibrator includes a targeted camera selector for selecting a targeted camera requiring the calibration, an intermediate camera selector for selecting an intermediate camera which is the in-vehicle camera that intervenes between the targeted camera and a criterial camera, a first calibrator for, when the intermediate camera is not selected, calibrating the targeted camera based on a captured image of an overlapping region between the criterial camera and the targeted camera, and a second calibrator for, when the intermediate camera is selected, calibrating the intermediate camera based on a captured image of an overlapping region between the criterial camera and the targeted camera, and then calibrating the targeted camera based on a captured image between the calibrated intermediate camera and the targeted camera.

Abstract: An image generation device for referencing a correspondence relationship and generating a line-of-sight-converted image from a captured image of an in-vehicle camera mounted to a vehicle is provided. The image generation device includes a first region updating unit that, upon sensing deviation of at least one of the mounting position and the mounting angle of the in-vehicle camera and calculating a new mounting position and mounting angle, updates a correspondence relationship of a predetermined first region in the line-of-sight-converted image in accordance with the new mounting position and mounting angle, and a second region updating unit that, upon satisfaction of a predetermined updating condition after updating the correspondence relationship of the first region, updates the correspondence relationship for a second region in the line-of-sight-converted image in accordance with the new mounting position and mounting angle.
