Research on Recognition Methods of Bus Front Road Condition Based on Video

摘要

Among safe driving systems of intelligent transportation, the road recognition for bus driving, Especially for front road driving condition, becomes more and more important. Moreover, improving the road recognition of public transport vehicles can greatly improve safe driving performance as well as safety and comfort of passenger. Road before driving generally includes vehicle, pedestrians and suspected obstacles, which can be detected based on image technology intuitively and quickly. Based on video image processing technology, using imaging principles, this paper predicts the bus driving route of next moment, and calculates the minimum safe distance after making Canny edge improved algorithm. Coupling radar real-time detects for speed and distance of obstacles in front, the real-time monitoring of road front driving for bus is realized. Finally, the collision avoidance simulation verifies the correctness of this method, which has very broad application areas.
