Three Dimensional Road Surface Shape Estimation Device, Three Dimensional Road Surface Shape Estimation Method, Three Dimensional Road Surface Shape Estimation System, And Three Dimensional Road Surface Shape Estimation Program

Abstract: The preset disclosure provides a road surface shape estimation device and the like capable of estimating the three-dimensional shape of a road surface easily and with high accuracy. The road surface shape estimation device according to the present disclosure includes: an identification unit that compares a first bird's-eye view obtained by converting a first image of a road surface captured from a first position into a bird's-eye view, and a second bird's-eye view obtained by converting a second image of the road surface captured from a second position different from the first position into a bird's-eye view and that identifies, for a plurality of portions of the road surface, a first portion in the first bird's-eye view and a second portion in the second bird's-eye view, the first portion and second portion corresponding to said plurality of portions; and an estimation unit that calculates an amount of movement on the image between the first portion and second portion and that estimates the uneven shape of the road surface on the basis of the amount of movement.
