在本文中，为了辅助老年人的视觉功能，我们提出了一种识别道路水平差异的方法。本文的重点在于检测由高度差引起的运动视差。针对道路标高差异的识别已经进行了一些研究。所提出的方法不同于那些使用多个摄像机和地标进行检测的研究。为此，我们仅使用一台摄像机。它注重道路高低差的点。根据观察者的运动，附近的点和远处的点似乎以不同的速度移动。在所提出的技术中，通过计算摄像机与道路上指定点之间的距离来识别道路水平差的存在。通过实验检验了该技术的性能并获得了有希望的结果
In this paper, to assist the visual function of elderly people, we propose a method of recognizing the difference in level on a road. The point of this paper is in the detection of the motion parallax caused by the height of the difference. Some researches have been performed for the recognition of road level difference. The proposed method differs from those researches which use multiple cameras and landmarks for the detection. We employ only a single camera for this purpose. It pays attention to the point of the road level difference. A nearby point and a distant point seem to move at a different speed depending on an observer's motion. In the proposed technique, the presence of the road level difference is recognized by calculating the distances between the camera and the specified points on the road. The technique was examined its performance by experiments and promising results were obtained
