Abstract

The invention, which relates to the technical field of automatic driving, discloses a positioning and identification method, device and equipment of an autonomous vehicle and a storage medium. The method comprises the following steps: acquiring a current positioning speed calculated by a global satellite navigation and positioning system at the current moment; acquiring a current actual speed of ato-be-identified vehicle; acquiring a historical positioning speed calculated by the global satellite navigation and positioning system at the moment of the previous period; acquiring a historical actual speed of the to-be-identified vehicle at the moment of the previous period; and thus identifying the accuracy of the positioning information of the global satellite navigation and positioning system according to the current positioning speed, the current actual speed, the historical positioning speed and the historical actual speed. Therefore, a technical problem of identifying the accuracy of the positioning information of the global satellite navigation and positioning system of the autonomous vehicle is solved.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to a method, device, equipment and storage medium for location recognition of an automatic driving vehicle. Background technique [0002] With the development of self-driving cars, the role of high-precision positioning systems in self-driving cars is becoming more and more important. Relying on centimeter-level high-precision positioning, self-driving vehicles can complete different driving tasks more safely and efficiently. Global Navigation Satellite System (GNSS) + Inertial Navigation System (Inertial Navigation System, INS) high-precision navigation is commonly used in self-driving vehicles to achieve high absolute positioning coordinates, supplemented by cameras and other sensors Fusion positioning is performed to achieve the purpose of lane level. The high-precision positioning system is actually a multi-sensor fusion positioning system. In such a multi-sen...
