Embodiment Construction

[0032] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0033] It can be understood that the terms "first", "second" and the like used in this application may be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one data from another. For example, a first variance value could be termed a second variance value, and, similarly, a second variance value could be termed a first variance value, without departing from the scope of the present application. Both the first variance value and the second variance value are variance values, but they are not...

Abstract

The present application relates to a location data correction method, device, computer equipment and storage medium. The method includes: acquiring the first positioning data at the first moment and the predicted first position data at the first moment; obtaining the positioning error value according to the first positioning data and the first position data; acquiring the position prediction error corresponding to the first time period value, wherein the first time period is the time period before the first moment; the first position data is corrected according to the positioning error value and the position prediction error value to obtain the target position data. Using the method of the present application can improve the accuracy of predicted location data.

Description

technical field [0001] The present application relates to the technical field of automatic driving, in particular to a position error correction method, device, computer equipment and storage medium. Background technique [0002] In the field of automatic driving, automatic driving usually needs to predict the driving route and driving position of the vehicle through the instruments in the vehicle, and then rely on the intelligent driver mainly based on the computer system to realize unmanned driving. However, the obtained position data predicted by the instrument in the traditional method is inaccurate. Contents of the invention [0003] Based on this, it is necessary to provide a location data correction method, device, computer equipment and storage medium to improve the accuracy of location data prediction in view of the above technical problems. [0004] A location data correction method, said method comprising: [0005] Acquiring the first positioning data at the f...
