Original Abstract Submitted
An estimation device includes a coordinate calculation unit, a feature obtaining unit, and a bird's-eye view generation unit. The coordinate calculation unit calculates three-dimensional coordinates of an object present around a vehicle based on two-dimensional images representing outside of a vehicle captured by a plurality of cameras mounted on the vehicle, by using a self-position estimation method including a visual odometry which calculates the three-dimensional coordinates of the object in sequential two-dimensional images captured by a same camera. The feature obtaining unit obtains a bird's-eye view (BEV) feature, which is a feature in a BEV space, based on the three-dimensional coordinates and at least one of the two-dimensional images by using a BEV estimation algorithm. The bird's-eye view generation unit generates a bird's-eye view based on the BEV feature.
