Abstract

The invention discloses an automatic driving navigation positioning precision evaluation method based on map matching. The method comprises the following steps that: a vehicle-mounted sensor transmitsa vehicle real-time signal to a vehicle real-time signal collection module, the vehicle real-time signal collection module transmits a collected electric signal to a processing module, map data is transmitted to the processing module at the same time, the processing module transmits comparison data to a central processing unit through a transmission module, the central processing module processesdata comparison information in a centralized mode, takes out effective information and transmits the effective information to an evaluation module, a judgment module judges evaluation information generated by the evaluation module, a secondary judgment module judges information processed by the judgment module, the secondary judgment module transmits and feeds back a judgment signal to the central processing module, the central processing module integrates and processes information and transmits the information to a misjudgment signal detection module for final signal judgment, and finally, final result data is transmitted through a processing result feedback module. According to the invention, the positioning precision and safety of an automatic driving automobile can be improved.

Description

technical field [0001] The invention relates to the field of automatic driving navigation positioning accuracy testing and processing, in particular to a map matching-based automatic driving navigation positioning accuracy evaluation method. Background technique [0002] With the maturity of artificial intelligence technology, autonomous driving technology has also developed rapidly. The vehicle positioning system is included in the automatic driving technology. The vehicle positioning system is a technology for locating the precise position and attitude of the self-driving vehicle in the world coordinate system. At present, it is necessary to evaluate the absolute accuracy of the vehicle positioning system to determine the accuracy of the vehicle pose determined by the vehicle positioning system. [0003] In the prior art, when evaluating the absolute accuracy of the positioning of the vehicle positioning system, the target lane line is compared with the standard main lane...
