AI Technical Summary

Problems solved by technology

First of all, the original data has the disorder of the vehicle identification ID. During the collection process, the vehicle identification ID generated by the fusion perception platform will change, which makes the test system unable to distinguish each vehicle; second, there are few vehicles in the original data. Some location points are inaccurate; finally, some data in the original data does not belong to the vehicle data that needs to be played back

Abstract

The invention belongs to the technical field of vehicle-road testing, and particularly discloses a data processing method and system for vehicle-road cooperation test scene acquisition and playback. The system comprises an intelligent sensing platform, a data storage module, a processor and a vehicle-road cooperation test platform. The intelligent sensing platform is installed on a vehicle and is used for acquiring information of a plurality of vehicles in a vehicle yard. The input end of the data storage module is connected with the output end of the intelligent sensing module, the output end of the data storage module is connected with the processor, the processor executes a method and carries out data processing, and the output end of the processor is connected with the vehicle-road cooperation test platform. By adopting the technical scheme, the data is corrected to smooth the vehicle track and clean the noise data through the method and the system, the processed data can be used for playback of the test scene, and the availability of the collected data and the authenticity of the test scene are improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle-road testing, and relates to a data processing method and system for collecting and playing back scenes of vehicle-road collaborative testing. Background technique [0002] C-V2X (Cellular-V2X, cellular vehicle networking) technology is currently ushering in a critical stage of development and commercialization, from the initial small-scale open roads to now discussing pre-installed mass production and large-scale deployment. Faced with the large-scale communication and application performance of LTE-V2X (Internet of Vehicles) in real traffic scenarios, researchers and testing institutions have developed some field test solutions and conducted a large number of tests in demonstration areas, such as M-city in Michigan, USA , the Intelligent Vehicle Integrated System Test Area (i-VISTA) in Chongqing, China, and AstaZero in Sweden. However, most of these field tests are carried out in a two-vehicle ...
