In a speed limit recognition method, a captured image representing an environment in front of a host vehicle is acquired from a camera. Then, a speed limit identifier is recognized from the captured image, a determination is made as to whether a plurality of speed limit identifiers are recognized from the captured image, and if it is determined that the plurality of speed limit identifiers are recognized, a determination is made as to whether the plurality of speed limit identifiers include speed limit identifiers indicating the same speed limit respectively present in the right front and left front of the host vehicle. When it is determined that the plurality of speed limit marks include speed limit marks indicating the same speed limit respectively present in the right front and the left front of the host vehicle, the speed limit indicated by the speed limit marks respectively present in the right front and the left front of the host vehicle is recognized as the speed limit of the host vehicle.
在限速识别方法中,从摄像机获取表示本车辆前方的环境的拍摄图像。然后,从拍摄图像识别限速标识,判定是否从拍摄图像识别出多个限速标识,在判定为识别出多个限速标识的情况下,判定多个限速标识是否包括在本车辆的右前方与左前方分别存在的表示相同限速的限速标识,在判定多个限速标识包括在本车辆的右前方与左前方分别存在的表示相同限速的限速标识的情况下,将在本车辆的右前方与左前方分别存在的限速标识所表示的限速识别为本车辆的限速。
