The invention discloses a navigation system and a navigation method therefor. The navigation system and the navigation method are used for guiding a mobile object to reach a destination along a plan path. The navigation system is provided with a photographic device for acquiring images in front of a mobile object in navigation, and with a comparison module for comparing the images acquired by the photographic device and data of landmarks through which the mobile object will pass in the plan path. If characteristics are conform, a navigation interface prompts the plan path in the way of inclusion of landmark data-related information and if the characteristics are not conform, the navigation interface prompts the plan path in the way of exclusion of the landmark data-related information. Therefore, the navigation system can realize effective and accurate navigation.

A system and method for processing a 3-dimensional landmark providing a 3-dimensional representation of a 3-dimensional real world object located at a predefined geographic location is provided. The method includes the steps of providing a data set containing the 3-dimensional landmark, determining a largest continuous horizontal surface of the 3-dimensional landmark, and storing the determined largest horizontal surface as road traffic area of a road network used by a user when moving on the object.

The invention relates to an AGV path navigation method assisted by a mechanical structure and an AGV chassis structure. The AGV path navigation method comprises a chassis, wherein solid rubber wheelsare arranged at two sides of the chassis, and reduction boxes for controlling the rotating speed of the solid rubber wheels are arranged at two ends of the upper part of the chassis; the middle part of the chassis is provided with an electromagnetic code disc, a protective shell is arranged above the electromagnetic code disc, and a first compression spring used for ensuring that the electromagnetic code disc does not slip is arranged in the protective shell; a first group of limit switches and a second group of limit switches are arranged at the lower part of the chassis in the direction of the vehicle head, and the first group of limit switches and the second group of limit switches are respectively arranged in two rows; the AGV with the chassis structure runs on a preset path, a grooveand a station landmark groove for representing a station are arranged on the ground of the path, a first group of limit switches fall into the groove when the AGV runs, a second group of limit switches fall into the station landmark groove, and a signal is output to a controller of the AGV, wherein the controller judges whether to carry out omnidirectional movement or differential steering according to the obtained information.
