CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 201910838298.6, filed on Sep. 5, 2019, titled “Method and apparatus for evaluating data, device, and computer-readable storage medium,” which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

Embodiments of the present disclosure mainly relate to the field of autonomous driving, and more specifically to a method and apparatus for evaluating data, a device, and a computer-readable storage medium.

BACKGROUND

High-precision positioning technology is an important part of autonomous driving technology, and is also the basis for path planning, control decision making, and perception by autonomous vehicles. Conventional positioning schemes mainly include a positioning scheme based on a global navigation satellite system (GLASS)/inertial measurement unit (IMU), a positioning scheme based on laser radar, and a positioning scheme based on a camera.

With the development of autonomous vehicle technology, it is very important to use the combination of GNSS/IMU and laser radar for mapping. The combination of the above three technologies may provide an accurate map for an autonomous vehicle to ensure correct driving of the vehicle. However, there are still many problems that need to be solved in the process of mapping through the combination of GNSS/IMU and laser radar.

SUMMARY

According to embodiments of the present disclosure, a solution to evaluating data is provided.

In a first aspect, an embodiment of the present disclosure provides a method for evaluating data. The method includes generating, at least based on satellite navigation data related to a vehicle, a reference position and posture data set of the vehicle. The method further includes generating, at least based on a part of the satellite navigation data, a test position and posture data set of the vehicle, accuracy of the test position and posture data set being lower than accuracy of the reference position and posture data set. The method further includes obtaining a revised position and posture data set for the test position and posture data set. The method further includes evaluating, based on the reference position and posture data set and the revised position and posture data set, a revision performance for the test position and posture data set.

In a second aspect, an embodiment of the present disclosure provides an apparatus for evaluating data. The apparatus includes a first reference position and posture data set generating module, configured to generate, at least based on satellite navigation data related to a vehicle, a reference position and posture data set of the vehicle; a test position and posture data set generating module, configured to generate, at least based on a part of the satellite navigation data, a test position and posture data set of the vehicle, accuracy of the test position and posture data set being lower than accuracy of the reference position and posture data set; a first revised position and posture data set obtaining module, configured to obtain a revised position and posture data set for the test position and posture data set; and a first evaluating module, configured to evaluate, based on the reference position and posture data set and the revised position and posture data set, a revision performance for the test position and posture data set.

In a third aspect, an embodiment of the present disclosure provides an electronic device, including: one or more processors; and a storage apparatus configured to store one or more programs, wherein the one or more programs, when executed by the one or more processors, cause the one or more processors to implement the method according to the first aspect.

In a fourth aspect, an embodiment of the present disclosure provides a computer-readable storage medium, storing a computer program thereon, where when the program is executed by a processor, the method according to the first aspect is implemented.

It should be appreciated that the description of the summary is not intended to limit the key or important features of the embodiments of the present disclosure, or to limit the scope of the present disclosure. Other features of the present disclosure will become readily comprehensible through the following description.
