自1991年以来，我们一直在开发机器人旅行援助（RoTA）系统，该系统可以在道路或人行道上引导盲人。对于RoTA来说，最困难的问题之一是如何在没有交通事故的情况下穿过十字路口。因此，本文提出了交叉口车辆危险度的估计方法。该方法在图像处理系统上实现。利用计算机视觉测量车辆的位置、速度和运动方向，并评估其危险系数。在真实的世界场景中，T形交叉口中约90%的车辆在危险判断中得到了正确的解释。
We have been developing Robotic Travel Aid (RoTA) system since 1991 which guides the blind on a road or a sidewalk. One of the most difficult problems for RoTA is how to cross the intersection without a traffic accident. So, danger estimation for vehicles at the intersection is proposed in this paper. This method is implemented on an image processing system. The location, velocity, and the moving direction of a vehicle are measured by computer vision and its danger coefficient is evaluated. About 90% of vehicles in a T-shaped intersection have been correctly interpreted in danger judgments in real world scenes.
