The invention discloses a plane and barrier detection method based on an RGB-D camera and an attitude sensor, and the method achieves the environmental three-dimensional information recognition with higher resolution, higher refresh rate and higher precision based on the RGB-D camera and the attitude sensor. The method can achieve the recognition of a ground passage, the judgment and early-warning of a ground cavity and various types of barriers and the recognition of scenes of going upstairs and downstairs, and is close to the visual sensing of an environment. Through the cooperation of the attitude sensor, a whole system is more flexible and portable, and the camera does not need to keep a fixed relative position with a user or any other ground reference object. When a visually-impaired person goes out, the camera can be placed at any body part which can photograph a three-dimensional environment. A portable computer or pad compatible with the RGB-D camera can be selected by himself or herself to achieve the same function.
