Abstract

The invention provides a system for an unmanned vehicle to sense an initial position in a weak signal scene. The system comprises two positioning tags arranged on the unmanned vehicle and three positioning base stations arranged in the weak signal scene; the two positioning tags comprise a tag I and a tag II; and the three positioning base stations comprise a base station I, a base station II and a base station III. The unmanned vehicle is provided with a central control system used for sending data to the positioning tags and receiving data from the positioning tags. By measuring and calculating the distance between the vehicle positioning tags and the positioning base stations, initial positioning of the unmanned vehicle in the weak signal scene is realized, self-sensing of the initial position of the vehicle can be realized without a GPS positioning signal. The system is applicable to multiple scenes and has a wide application range.

Description

technical field [0001] The invention relates to the technical field of unmanned vehicle positioning, in particular to a system and method for an unmanned vehicle to sense an initial position in a weak signal scene. Background technique [0002] In areas such as remote mountainous areas, underground garages, and inside buildings, due to the weak satellite navigation signal, the unmanned networked vehicle cannot perceive its own location, and the vehicle cannot operate. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a system and a method for an unmanned vehicle to perceive an initial position in a weak signal scene, which meets the positioning requirements of an unmanned vehicle in a weak signal scene. [0004] The specific plan is as follows: [0005] The system for perceiving the initial position of an unmanned vehicle in a weak signal scene is characterized in that it includes two positioning tags set on the unman...
