A data processing method and system for intelligent vehicle behavior description

Abstract

The embodiment of the present invention relates to a data processing method and system for intelligent vehicle behavior description, the method includes: acquiring environment perception information and vehicle state information; extracting behavior parameters and state parameters of intelligent vehicles; extracting behavior parameters and state of obstacles Parameters; generate the execution object field, driving action field, executed object field and constraint condition field; call the driving statement structure model, splicing the fields into driving behavior statement information; carry out semantic recognition and analysis on the driving behavior statement, and obtain the predictive operation of obstacles Trajectories and state machine behavior information of intelligent vehicles; generate running trajectories of intelligent vehicles. The present invention can describe the complex behavior of intelligent vehicles and targets accurately, clearly and in detail through the driving sentence structure model, thereby accurately planning the running track of intelligent vehicles, and simplifying the complexity of the system, thus improving the efficiency of intelligent vehicle path planning. time.

Description

technical field [0001] The present invention relates to the technical field of intelligent driving, in particular to a data processing method and system for intelligent vehicle behavior description. Background technique [0002] With the development of artificial intelligence technology and modern manufacturing industry, autonomous driving technology has gradually entered people's daily life, subtly changing the way people travel. Autonomous driving technology has great application prospects in both military and civilian applications. For military use, it can be used not only as an unmanned transportation platform, but also as an unmanned demolition vehicle, unmanned combat platform, unmanned patrol and surveillance vehicle, etc.; in civilian use, it can not only bring convenience to human life, but also reduce The incidence of traffic accidents and the improvement of road traffic efficiency. [0003] Autonomous driving behavior planning is an important part of driving bra...

Problems solved by technology

[0004] The label-based behavior description method in the prior art can only express simple motion behaviors, and cannot describe complex behaviors such as giving way and giving way, and the description of behaviors lacks depth, resulting in the inability of the vehicle to drive accurately; moreover, the existing technology A set of behavior description specifications has not been established, lack of standardization and modular structure, which is not conducive to the incremental generation of new behaviors; in addition, existing technologies usually use other methods to describe other target behaviors in the scene, increasing the complexity of the system
