Abstract

The present invention relates to a vehicle collaborative positioning method, system, device and computer-readable storage medium in an intelligent networked environment. The method includes the following steps: obtaining the distance between intelligent networked devices, and according to the According to the distance between the vehicles and the latitude and longitude information of the vehicle, the preliminary estimated position of the vehicle to be positioned at the current moment and the preliminary estimated position of the vehicle to be positioned after the predetermined time are obtained; according to the preliminary estimated position of the vehicle to be positioned at the current moment and the dead reckoning algorithm, after the predetermined time is obtained Another preliminary estimated position of the vehicle to be positioned; performing data fusion on the preliminary estimated position and another preliminary estimated position to obtain a final estimated position of the vehicle to be positioned after a predetermined time. The vehicle cooperative positioning method under the intelligent network connection environment provided by the present invention improves the positioning accuracy of the vehicle.

Description

technical field [0001] The present invention relates to the technical field of vehicle positioning, and in particular to a vehicle collaborative positioning method, system, device and computer-readable storage medium in an intelligent network environment. Background technique [0002] With the rapid development of intelligent transportation systems and Internet of Vehicles technology, intelligent applications based on intelligent Internet of Things technology have an increasingly urgent need to improve the accuracy of vehicle positioning. Existing vehicle positioning methods include vehicle positioning using reference positions such as lane lines and guardrails, and satellite positioning methods. For the former, it is actually interfered by the environment outside the vehicle, and the wireless signal is attenuated. The signal strength received by the vehicle may be greatly different from the theoretical value, resulting in low vehicle positioning accuracy. For the latter, i...
