Embodiment 1

[0028] figure 1 It is a schematic flowchart of a method for generating positioning test data provided by Embodiment 1 of the present invention. This embodiment is applicable to obtaining positioning data in any scenario, and the method can be executed by a device for generating positioning test data. The device can Realized in the form of software and / or hardware.

[0029] Such as figure 1 Described, the method of the present embodiment comprises:

[0030] S110. Obtain positioning data collected by conducting actual vehicle measurements on a sample geographical area in a set scene as set sample data.

[0031] It should be noted that the objects in the social environment may include static objects and moving objects. Wherein, the stationary objects may be roads, trees, buildings and so on. The moving objects can be vehicles, pedestrians, etc. driving on the road. When collecting data information in a social environment object, it can be obtained through a collection device...

Embodiment 2

[0053] On the basis of the above embodiments, it can be known that, according to the setting sample data and the reference sample data, the difference characteristics between the positioning data of the setting scene and the positioning data of the reference scene can be determined. When the positioning data are different, the corresponding determined difference features are also different.

[0054] Optionally, the positioning data is point cloud data, then determining the difference feature according to the point cloud data may be: for a set of the set sample data and the reference sample data, respectively calculate the average value of the point cloud reflection intensity, and calculate Mean difference, wherein, the set of the set sample data and the reference sample data are the positioning data of a unit area in the sample geographical area; The concentration range value of the corresponding reflection intensity mean difference value is used as the difference feature.

Abstract

The embodiment of the invention discloses a method, an apparatus and a device of generating positioning test data and a storage medium. The method comprises the steps of: acquiring positioning data collected through actual measurement of a vehicle for a sample geographical area in a set scene as setting sample data; obtaining positioning data collected through actual measurement of the vehicle forthe sample geographical area in a reference scene as setting sample data as reference sample data; determining the difference characteristics of the positioning data of the set scene and the positioning data of the reference scene according to the set sample data and the reference sample data; and according to the difference characteristics and the actual measured positioning data of a target geographical area, generating the simulated positioning data of the target geographical area in the set scene. The technical solution of the embodiment of the present invention can be used to determine the positioning data of the set scene in a certain area by using different characteristics in different scenes to improve the convenience of obtaining the positioning data in various areas and variousweathers so as to facilitate test.

Description

technical field [0001] Embodiments of the present invention relate to positioning data processing technologies, and in particular to a method, device, equipment and storage medium for generating positioning test data. Background technique [0002] With the improvement of the automation technology level of vehicle driving, various vehicle positioning technologies are also continuously developed. Common vehicle positioning methods include: satellite positioning, cellular base station positioning, laser point cloud positioning, and ultrasonic positioning. Various positioning methods need to install different detection equipment on the vehicle, and use software algorithms to calculate positioning data. Various hardware and software constitute a positioning system. [0003] Different positioning systems have their own applicable conditions and corner cases. To find more problems during offline testing, a large amount of positioning data is required to cover, that is, to calculat...
