%X Elicited by the original steoro matching method, considering the specialities of the obstacle detection task, and in order to cope with its difficulties, a new fast and robust obstacle detection method is presented in this paper. Being different from origin methods based on the depth of obstacl object, the presented method uses a newcharacterization-plan s direction. This charaction identifies the vertical surface of obstacle object from thehorizonal surface of ground.
