To provide a road surface drawing device which matches a path of a vehicle to a path display image on a road surface following the change in the orientation of the travel vehicle at the time of right turn, left turn and the like.SOLUTION: A road surface drawing device comprises: a vehicle path acquisition unit 20 which acquires path information of a vehicle 1; a vehicle state information acquisition unit 30 which acquires the position and orientation of the vehicle as vehicle state information; an image selection unit 40 which selects a path display image projected on the front road surface of the vehicle on the basis of the path information and the vehicle state information; and a road surface drawing unit 50 which projects the path display image to the front road surface. The image selection unit 40 selects the path display image 6 including a line indicating the second direction from the vehicle 1 when the path information changes to the second direction from the first direction, and re-selects the path display image 6 following the change of the vehicle state information.SELECTED DRAWING: Figure 2

    【課題】右折、左折時等での走行車両の向きの変化に伴い、車両の進路と路面上での進路表示画像が一致するような路面描画装置を提供する。【解決手段】車両(1)の進路情報を取得する車両進路取得部(20)と、車両の位置と向きを車両状態情報として取得する車両状態情報取得部(30)と、進路情報と車両状態情報に基づいて、車両の前方路面に投影する進路表示画像を選択する画像選択部(40)と、前方路面に進路表示画像を投影する路面描画部(50)とを備え、画像選択部(40)は、進路情報が第1方向から第2方向に変化する場合、車両(1)から第2方向を示す線を含む進路表示画像(6)を選択し、車両状態情報の変化に伴って、進路表示画像(6)を再選択することを特徴とする。【選択図】図2
