中国汽研:自动驾驶仿真测试场景库体系建设方法综述
论文：自动驾驶仿真测试场景库体系建设方法综述
摘要：基于自动驾驶仿真测试场景库可以有效加速测试进度，提高测试的安全性和覆盖度。对自动驾驶中的场景进行分析，论述了相关的场景定义、场景元素以及场景来源；对场景中的数据处理、特征提取、场景聚类进行描述，总结提出自动驾驶测试仿真场景库的体系搭建方法，并对未来发展趋势做了相关预期分析，可以为自动驾驶测试开发提供参考和借鉴。
“如何利用有限的测试场景去映射出无限丰富的世界是实现自动驾驶测试验证的关键。”最近对这句话深有体悟，一味地追求测试量级没有意义，用尽可能简单的场景去简化世界，覆盖世界才重要。
自动驾驶场景的定义：时间序列中自动驾驶车辆和周围环境各元素动态组合的描述。自动驾驶场景具有无限丰富、难以预测、不可穷尽等特点。
聚类分析的核心就是将相似度较高的对象或者元素分为一类，相似度较低的元素进行拆分。
