Various aspects of methods, systems, and cases for adaptive generation and modification of autonomous driving scenarios tested in an autonomous driving simulation platform are described. In an example, a method for autonomous driving scene evaluation includes identifying a first scene for use in a simulation, the first scene defined by a first set of scene parameters; identifying a first risk assessment metric for the first scene based on a safety operation used by the autonomous driving model in the first scene; determining a second (altered) set of scene parameters from the changes to the first set of scene parameters based on a second risk assessment metric; and generating a second scene based on the second (altered) set of scene parameters. For example, the second autonomous driving scenario may be more difficult for safety operations than the first risk assessment metric, thereby achieving an increase in test complexity.
描述了用于在自主驾驶模拟平台中进行测试的自主驾驶场景的自适应生成和修改的方法、系统和用例的各个方面。在示例中,用于自主驾驶场景评估的方法包括:标识用于在模拟中使用的第一场景,该第一场景由第一场景参数集合限定;基于由第一场景中的自主驾驶模型使用的安全性操作来标识第一场景的第一风险评估度量;基于第二风险评估度量来从第一场景参数集合的改变中确定第二(改变的)场景参数集合;以及基于该第二(改变的)场景参数集合来生成第二场景。例如,第二自主驾驶场景可以比第一风险评估度量对安全性操作具有更大的难度,从而实现测试复杂性的增加。
