Abstract

The embodiment of the invention relates to a data processing method and device, a server, a terminal and a readable storage medium. The method comprises the following steps: acquiring IMU data of a vehicle reported by a terminal; wherein each piece of sampling data in the IMU data has a time attribute; processing the IMU data according to the time attribute of each piece of sampling data to obtainerror correction data of the IMU data; wherein the error correction data is related to median data of the IMU data; and correcting each piece of sampling data by adopting the error correction data toobtain corrected IMU data. By adopting the method, the data precision of the IMU data of the vehicle can be improved.

Description

Technical field [0001] The embodiments of the present disclosure relate to the field of data processing technology, and in particular, to a data processing method, device, server, terminal, and readable storage medium. Background technique [0002] An Inertial Measurement Unit (IMU) is a device that measures the attitude angle (or angular rate) and acceleration of an object. Generally, an IMU contains three single-axis accelerometers and three single-axis gyroscopes, which are used to measure acceleration data and angular velocity data of an object in a three-dimensional space, namely IMU data. [0003] At present, IMU data is widely used in projects such as autonomous driving, navigation systems, and driving safety. Taking driving safety as an example, the driver’s terminal is equipped with an IMU, and the terminal measures the IMU data of the terminal through the IMU and reports it to the management background; the management background obtains the IMU data and then performs dat...
