Abstract

The invention provides a positioning method and system for an autonomous vehicle. The method comprises the steps of acquiring a sign board picture, wherein the sign board picture is a picture obtainedby shooting a sign board pre-arranged on a running route; recording shooting time of the sign board picture, and identifying space information from the sign board picture; determining a geometric distance from the vehicle to the sign board according to the sign board picture; sending the space information and the geometrical distance from the vehicle to the sign board to a vehicle-mounted serveror a cloud server, wherein the vehicle-mounted server or the cloud server is used for performing analysis processing on the space information and the geometric distance from the vehicle to the sign board so as to obtain a vehicle positioning result; and receiving the vehicle positioning result sent by the vehicle-mounted server or the cloud server. Therefore, accurate positioning of the autonomousvehicle can be realized without depending on satellite signals; the positioning precision is high; and the implementation is easy.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to a positioning method and system for an automatic driving vehicle. Background technique [0002] The current navigation technology is mainly based on satellite signals for real-time positioning, but in some areas where satellite signals are weak or there is no satellite signal, it is difficult to perform accurate positioning. For example: outdoor closed non-public transportation areas such as residential quarters, factories, airports, and amusement parks; indoor closed non-public transportation areas such as airport waiting halls, large waiting rooms, large shopping malls, storage warehouses, and large museums; ground roads , Elevated highways, bridges, tunnels and other outdoor public transportation areas, etc. [0003] Existing satellite navigation systems for vehicles cannot provide accurate lane-level positioning information, and it is difficult to accurately navi...
