Abstract
A camera parameter estimating device includes: a camera position posture acquisition unit acquiring estimated position and posture of a camera, based on a captured image acquired by the camera; a first vector calculation unit calculating a first vector corresponding to a traveling direction of the vehicle; a second vector calculation unit calculating a second vector corresponding to a normal direction of a plane corresponding to a road surface on which the vehicle travels; a third vector calculation unit calculating a third vector orthogonal to the first and second vectors; and a camera parameter estimation unit estimating an actual installation posture of the camera on the basis of the first, second and third vectors and the estimated posture of the camera when the estimated position moves along a direction indicated by the first vector.
