Abstract

The invention provides a generation method for general amplification of an intelligent automobile recombination scene, which comprises the following steps: determining key elements, including static elements and dynamic elements, for scene generation according to test requirements, and setting related fields for each kind of information; determining a value domain of each element field and whetherthe element fields have correlation or not by using a statistical analysis method based on historical data of a natural driving database, and randomly selecting and traversing elements without correlation in the value domain; for elements with correlation, obtaining constraint conditions through a statistical analysis method, and carrying out selection in a value domain corresponding to the constraint conditions of the fields. According to the generation method for universal amplification of the intelligent automobile recombination scene, the recombination scene can be rapidly generated, scene amplification is achieved, and the purpose of covering all possible working conditions is achieved.

Description

technical field [0001] The invention belongs to the field of research and development of automatic driving vehicles, and in particular relates to a method for generating general amplification of intelligent vehicle reorganization scenarios. Background technique [0002] Driving scene data is the basic data resource for the R&D and testing of intelligent connected vehicles, an important "case library" and "exercise set" for evaluating the functional safety of intelligent connected vehicles, and a key data basis for redefining the level of intelligent vehicles. Driving scene test cases are mainly reproduced through the virtual simulation environment and tool chain, so building a virtual scene database is a key bridge connecting scene data and scene applications. Under the current technical conditions, due to the lack of a systematic driving scene generation method, there is a problem that the construction of the scene library is not complete enough to completely cover all poss...
