Abstract
A map creation device including an odometry information calculator calculating odometry information indicating an amount of movement of a vehicle; an initial value calculator calculating, from the odometry information, an initial value of a homography matrix between images obtained by an in-vehicle camera photographing different locations; and an optimal value calculator calculating, by iterative computation, an optimal value of the homography matrix from the calculated initial value and a luminance value of each pixel included in a road-surface region specified in the images. The device also includes a camera position and orientation calculator calculating an amount of change in camera position and an amount of change in camera orientation of the in-vehicle camera by resolving the optimal value; and a three-dimensional position calculator calculating three-dimensional positions of features in the images from the amount of change in camera position and in camera orientation.
