Problems solved by technology

[0003] However, in the process of vehicle trajectory recording, when the positioning signal is weak, such as in densely built places, the positioning data acquired by the receiver is not accurate, which makes the positioning effect unsatisfactory, causing the vehicle's driving trajectory to drift, which cannot be achieved. Its due function, even due to errors in the positioning data and other problems such as errors in the driving route record, when the user queries the vehicle's driving track on the platform, it is easy to see that when the vehicle stops, there is still a driving track or waiting for a red light at the intersection At this time, the vehicle trajectory has drifted to other roads, which greatly affects the user experience

Abstract

The invention discloses a vehicle positioning data acquisition method and device, vehicle-mounted equipment and a storage medium, and the method comprises the steps: receiving the positioning data ofa vehicle, and detecting whether the vehicle is in a driving state or not; when the vehicle is in the driving state, judging whether the driving state of the vehicle is abnormal or not according to the positioning data; when the driving state of the vehicle is abnormal, filtering the positioning data; and when the driving state of the vehicle is not abnormal, sending the positioning data to a server. According to the method provided by the invention, relatively accurate positioning data can be obtained so that a vehicle driving track formed by the obtained positioning data subsequently does not have a drifting phenomenon and the driving track is smooth and accurate.

Description

technical field [0001] The present application relates to the technical field of positioning data processing, and in particular, to a method, a device, a vehicle-mounted device, and a storage medium for acquiring vehicle positioning data. Background technique [0002] Satellite positioning technology refers to a positioning technology that determines the position of the receiver by using the two-way communication between the satellite and the receiver. Common scenarios using satellite positioning technology are the recording of travel trajectories when traveling outdoors, and the recording of driving trajectories when vehicles are traveling. [0003] However, in the process of recording the vehicle's driving track, when the positioning signal is weak, such as in densely populated areas, the positioning data obtained by the receiver is inaccurate, which makes the positioning effect unsatisfactory and causes the vehicle's driving track to drift. Its proper function, even if t...
