Simulation test scene generation method and device based on automatic driving

Abstract

The invention provides a simulation test scene generation method and device based on automatic driving, and the method comprises the steps: obtaining a scene parameter dictionary according to obtained user input data; wherein the user input data comprises a function scene and a value range of a scene parameter corresponding to the function scene; matching and screening pre-generated scene templates according to the scene parameter dictionary to obtain a target scene template; and based on the scene parameter dictionary, expanding the target scene template to obtain a simulation test scene. According to the invention, the scene parameter dictionary is dynamically adjusted through the obtained user input data, so that the corresponding simulation test scene is automatically generated according to different user test requirements, the scene generation efficiency and quality are improved, the test feasibility is improved, the cost is reduced, and the waste of resources and cost is avoided.

Description

technical field [0001] The invention relates to the technical field of automatic driving simulation, in particular to a method and device for generating a simulation test scene based on automatic driving. Background technique [0002] Autonomous driving is one of the hot research fields in recent years. Due to factors such as complex and changeable traffic scenarios and expensive test costs, it is difficult for traditional open road tests and closed proving ground tests to meet the reliability and robustness requirements of autonomous driving technology. Therefore, the simulation based on digital virtual simulation technology has become one of the important means of automatic driving simulation testing. [0003] At present, the methods of simulation test scene generation mainly include two categories. One is the simulation scene generation method based on the scene mechanism. According to the researchers' understanding of the internal changes of the scene system and the prof...
