Claim One:
1. A device for calculating one or more camera parameters, the device comprising: a camera; a location information acquisition unit that acquires location information about a current location of the traveling vehicle; a road width information acquisition unit that acquires road data corresponding to the current location based on the location information and acquires road width information relating to a width of a road on which the traveling vehicle moves at the current location from the road data; a scenery image acquisition unit that acquires a scenery image from the camera; a camera parameter calibration unit that performs calibration calculation of the one or more camera parameters based on the scenery image and the road width information, wherein the device converts the scenery image captured by the camera of a scenery including the road on which the traveling vehicle moves, the one or more camera parameters that are calculated include a height of a mount position of the camera relative to the road and a direction of the camera; and displaying on a screen the converted scenery image, wherein the height of the mount position of the camera is calculated based on a ratio of a road width as displayed on the screen to the width of the road wherein the camera parameter calibration unit performs calibration calculation when a road condition determination unit determines that the road satisfies predetermined road conditions based on each of the following: i) the width of the road around the current location, ii) a number of lanes of the road around the current location, iii) whether a road type of the road around the current location is classified into a narrow street, iv) a link type of a link related to the road around the current location, v) an inclination of the road around the current location, vi) a curvature of the road around the current location, and vii) a connection angle formed between a link related to the road around the current location and another link connected thereto.
