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 present application discloses a vehicle positioning data acquisition method, device, vehicle-mounted device and storage medium, wherein the method includes: receiving the positioning data of the vehicle and detecting whether the vehicle is in a driving state; when the vehicle is in a driving state, according to The positioning data determines whether the driving state of the vehicle is abnormal; when the driving state of the vehicle is abnormal, the positioning data is filtered; when the driving state of the vehicle is not abnormal, the positioning data is sent to the server. The method provided by the present application can acquire relatively accurate positioning data, so that the vehicle driving trajectory formed by the acquired positioning data subsequently has no drift phenomenon, and the driving trajectory 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...
