Problems solved by technology

The disadvantages are also obvious: 1. The cost is high; 2. The amount of data is huge, and even if there is a huge amount of data, it can only reflect part of the dynamic traffic scene
[0004] It can be seen that the generation method of the dynamic traffic scene for the simulation test provided by the prior art cannot provide a sufficiently real dynamic traffic environment with massive data for the simulation system of the automatic driving, thereby ensuring the effectiveness of the training or verification of the automatic driving system in the simulation system. sex

Abstract

The invention relates to the technical field of automatic driving simulation, in particular to a traffic scene generation method, system and device, computer equipment and a storage medium. The traffic scene generation method is applied to an on-site terminal and comprises the following steps: acquiring road on-site dynamic traffic data; And processing the dynamic traffic data to obtain dynamic traffic element semantic description information and dynamic traffic element motion information, and transmitting the dynamic traffic element semantic description information and the dynamic traffic element motion information to a cloud. The traffic scene generation method is applied to a cloud end and comprises the following steps: acquiring dynamic traffic element semantic description informationand dynamic traffic element motion information transmitted by a field end; And generating a dynamic traffic scene according to preset static traffic scene data, the virtual dynamic traffic elements and the dynamic traffic element motion information. According to the method, the dynamic simulation site is generated by collecting the data of the road site, and a more real dynamic traffic scene can be provided for the automatic driving simulation system, so that the effectiveness of the automatic driving simulation system is improved, and the road test mileage is greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of automatic driving simulation, in particular to a dynamic traffic scene generation method, system, device, computer equipment and storage medium. Background technique [0002] Self-driving vehicles must undergo a large number of road tests to verify their safety and reliability. Due to the huge test mileage (millions of kilometers) and the inability to create extreme traffic accident scenarios, simulation testing has become a necessary tool for training and verification of self-driving vehicle algorithms. This has become the industry consensus. [0003] The simulation system usually uses the following methods for the construction of dynamic traffic scenes: 1. Structural method (typical scene method). This is a common scene construction method for ADAS systems (Advanced Driving Assistant System, that is, advanced driving assistance systems) for field testing and simulation testing. It is characteri...
