Abstract

The embodiment of the invention provides an automatic driving scene generation method and device and a storage medium. The method comprises the steps: inputting traffic network information and randompositioning points into a pedestrian behavior generator to generate an initial pedestrian trajectory; inputting the traffic network information and the random positioning points into an obstacle vehicle behavior generator to generate an initial obstacle vehicle track; according to a pedestrian behavior discriminator, discriminating the trueness of the initial pedestrian trajectory to obtain a first discrimination result; according to an obstacle vehicle behavior discriminator, discriminating the trueness of the initial obstacle vehicle trajectory to obtain a second discrimination result; obtaining a comprehensive discrimination value according to the first discrimination result and the second discrimination result; and if the comprehensive discrimination value does not accord with the preset condition, adjusting parameters of the pedestrian behavior generator and the obstacle vehicle behavior generator, and then re-executing the generation step and the discrimination step until the comprehensive discrimination value accords with the preset condition. According to the embodiment of the invention, the trueness of a simulation scene and the accuracy of a simulation test can be improved.

Description

technical field [0001] The present invention relates to the technical field of automatic driving simulation, in particular to a method, device and storage medium for generating an automatic driving scene. Background technique [0002] In the simulation, it is necessary to construct a simulation scenario for the autonomous vehicle. At this stage, autonomous driving scenarios mainly rely on manual editing and on-the-road collection, which is inefficient and limited by the collection location, which may make the simulation results inaccurate. Contents of the invention [0003] Embodiments of the present invention provide a method, device and storage medium for generating an automatic driving scene, so as to solve one or more technical problems in the prior art. [0004] In a first aspect, an embodiment of the present invention provides a method for generating an automatic driving scene, including: [0005] The traffic road network information and the random positioning poin...
