Abstract

The invention discloses an intelligent network connection vehicle test field data acquisition and fusion method and system. The method comprises the steps of: 1, building a static layer of a map in atest field according to the collected static data in the test field; 2, tracking a dynamic target in a sensing range by a roadside dynamic data acquisition module, and generating a flight path data management file under a corresponding label; 3, acquiring own vehicle position data, own vehicle driving state data and own vehicle surrounding environment data through a vehicle end dynamic data acquisition module, and performing preliminary fusion on the track of the dynamic target through a vehicle-mounted computing unit; 4, constructing a dynamic layer of a map in the test field by a data fusionand visualization module; 5, simulating various traffic scenes required by the intelligent network connection vehicle test in an adding and changing mode; and 6, performing real-time display throughthe data fusion and visualization module and transmitting the data to a test intelligent network connection vehicle for testing. According to the invention, various types of information in the test field can be comprehensively collected.

Description

technical field

[0001] The invention relates to the technical field of automatic driving, in particular to a method and system for data collection and fusion of an intelligent networked vehicle test field. Background technique

[0002] Intelligent networked vehicles are new types of vehicles equipped with vehicle-end dynamic data acquisition modules and V2X equipment. They pursue "safety, comfort, efficiency, and energy saving" during driving, and play a great role in alleviating traffic congestion and reducing the incidence of accidents. potential, the testing of intelligent networked vehicles has a very important impact on its development. At present, the United States, Japan, and Europe are all establishing and improving their own intelligent network test fields, and my country's intelligent network vehicle test fields are also under construction.

[0003] How to reasonably and perfectly collect and utilize the data in the test field of intelligent networked vehicles is ...
