A road surface projection device that projects an image onto a road surface is provided with: a projection unit (17) that projects the image onto a projection surface of the road surface within a predetermined distance from a vehicle; and a projection control unit (16) that controls the projection of the image. The projection control unit (17) performs control so as to project the image onto the projection surface in different forms, for example, a form in which the image is projected with normal visual observability, or a form in which the image is projected while the projection is stopped or the visual observability is reduced, in accordance with whether the projection surface is flat or not. According to the road surface projection device of the present invention, safer driving assistance can be performed by combining the projection form of road surface condition change information.

    本发明提供一种路面投影装置,其向路面投影图像,该路面投影装置具有:投影部(17),其将图像投影至离车辆处于预设距离内的路面的投影面;及投影控制部(16),其对图像的投影进行控制。投影控制部(17)根据投影面是否平坦进行控制,以将图像以不同的形态投影至投影面,所述不同的形态为例如以通常的视觉观察性进行投影的形态、及停止投影或者降低视觉观察性地进行投影的形态。根据本发明的路面投影装置,能够通过结合路面状况变更信息的投影形态来进行更安全的驾驶辅助。
