To create a map with high accuracy.SOLUTION: A map creation device includes: an acquisition unit configured to acquire an image captured by a camera mounted on a vehicle; a first estimation unit configured to estimate a first position indicating a position of the vehicle and an error of the first position based on information indicating a traveling state of the vehicle; a second estimation unit configured to estimate a second position indicating the position of the vehicle and an error of the second position based on radio waves transmitted from artificial satellites; and a creation unit configured to set position information of the vehicle preferentially using one position with a smaller error of the first position and the second position, and create a map of places in which the vehicle has traveled based on the set position information of the vehicle and the image.SELECTED DRAWING: Figure 2
【課題】高精度な地図を生成すること。【解決手段】実施形態の地図生成装置は、車両に搭載されたカメラにより撮像された画像を取得する取得部と、前記車両の走行状態を示す情報に基づいて、前記車両の位置を示す第1位置および前記第1位置の誤差を推定する第1推定部と、人工衛星から到来する電波に基づいて、前記車両の位置を示す第2位置および前記第2位置の誤差を推定する第2推定部と、前記第1位置および前記第2位置のうち、誤差が小さい一方の位置を優先して前記車両の位置情報を設定し、設定した前記車両の位置情報と、前記画像とに基づいて、前記車両が走行した場所の地図を生成する生成部と、を備える。【選択図】図2
