Virtuality and reality combined internet of vehicles application scene test system and method

Abstract

The invention relates to a virtuality and reality combined internet-of-vehicles application scene test system and method. The scene test system comprises a sensor equipment layer, an abstract sensor interface layer, a data fusion layer, a world model layer, an application layer, a database and a scene imagination layer, wherein the sensor equipment layer is used for obtaining and sending real scene data and virtual scene data; the abstract sensor interface layer is used for separating the data fusion layer, the application layer ad the sensor equipment layer, and providing data reading interfaces for the data fusion layer, the world model layer and the application layers after the separation; the data fusion layer is connected with the abstract sensor interface layer and is used for collecting and integrating the acquired scene data; the world model layer is used for receiving the integrated scene data so as to construct a world model; the application layer is used for carrying out scene test in the world model; the database is used for storing the data; and the scene imagination layer is sued for constructing virtual scenes and importing virtual scene data into the database. Compared with the prior art, the system and method have the advantages that virtuality and reality combined scene test can be realized, the equipment transportability is strong, the scenes can be played back and the test is simple, convenient and efficient.

Description

technical field [0001] The invention relates to the field of application systems of the Internet of Vehicles, in particular to a system and method for testing application scenarios of the Internet of Vehicles combined with virtual and real. Background technique [0002] Intelligent and connected vehicles have become the national strategic planning of developed countries such as the United States, Europe, and Japan. World-renowned vehicle companies are also investing huge sums of money in the research and development of intelligent and connected vehicles. Not only that, Internet giants are already one step ahead of traditional vehicle companies and have begun to deploy in this field. The intelligent networked car consists of two parts, one is the networked car, which realizes collaborative intelligent driving based on the Internet of Vehicles; the other part relies on sensing devices such as cameras and lidar, through ADAS (Advanced Driver Assistant Systems, advanced driver a...

Problems solved by technology

[0004] At present, a variety of application scenarios have been developed for different driving needs. The design of the entire Internet of Vehicles application is divided into two stages: development and testing. The testing of application scenarios is an important way to ensure the applicability of functions. It is not easy to encounter in the environment, but it is indispensable, and the current test system of the Internet of Vehicles is based on the real data collected by the sensor to carry out test activities in the real field, so there are more obvious problems: 1. Developed for the application of the Internet of Vehicles The system often does not have the ability to test and analyze, and can only carry out empirical tests in real environments, and the test cost is too high; 2. Some dangerous traffic scenes in reality are not conducive to carrying out empirical tests; 3. The application of Internet of Vehicles application systems Parts are too tightly coupled with specific devices, and the portability between different devices is poor. The connected devices are not transparent to the application layer, and cannot support testing for virtual devices; 4. The application system and the test system are independent. Unable to reproduce actual traffic scenarios during lab testing
