Abstract

The invention provides an abnormal value elimination method and device for vehicle-mounted high-precision positioning data and electronic equipment, and the method can accurately and reliably eliminate an abnormal value in the vehicle-mounted high-precision positioning data, prevents an automatic driving vehicle from mistakenly using the abnormal value of the positioning data to cause a dangerous accident, improves the safety of the automatic driving vehicle, and improves the safety of the automatic driving vehicle. The technical problem that abnormal values in the vehicle-mounted high-precision positioning data cannot be accurately eliminated in the prior art is relieved.

Description

technical field [0001] The present invention relates to the technical field of vehicle positioning, in particular to a method, device and electronic equipment for removing outliers of vehicle-mounted high-precision positioning data. Background technique [0002] In the field of autonomous driving, the accuracy of high-precision positioning data is crucial to the safety of autonomous driving. [0003] Because the positioning signal is poor in places with obstructions such as tunnels and buildings, or due to the influence of electromagnetic interference, ionospheric scintillation, or device abnormalities, the positioning results are often inaccurate. The outliers of the fine location data are identified, and the identified outliers are eliminated. How to accurately identify and eliminate outliers in high-precision positioning data has become a technical problem that needs to be solved urgently. [0004] To sum up, there is no effective solution for how to accurately remove o...
