The invention discloses a scene classification extraction method for automatic driving test data. The method comprises the following steps: 1) analyzing signals of road test data in a time slice form; 2) performing scene classification on the road test data; 3) compiling an extraction rule; 4) compiling an extraction code; 5) obtaining a time range of the corresponding scene according to the extracted code; and 6) segmenting and extracting the scene data in the time range, and marking corresponding scene types. According to the method, signals of road test data are analyzed in the form of time slices, scenes are divided into eight large classes and 51 small classes, extraction rules and extraction codes are written according to different types of scenes, and then original scene data in a time range are segmented and extracted according to the segmented time range; the method can effectively solve the problems of few extraction types and low automation degree of the current scene extraction method of the automatic driving test data, and achieves the effects of enabling the scene extraction types to be more comprehensive and reducing the difficulty of the automatic driving test.
本发明公开了一种自动驾驶测试数据的场景分类提取方法,包括如下步骤:1)以时间片的形式解析路试数据的信号;2)对路试数据进行场景分类;3)编写提取规则;4)编写提取代码;5)根据提取代码得到对应场景的时间范围;6)将时间范围内的场景数据切分提取出来并标注对应的场景类型。本发明以时间片的形式解析路试数据的信号,将场景分为8大类、51小类,根据不同类型的场景,编写提取规则和提取代码,然后切分的时间范围,将该时间范围的原场景数据切分提取出来;可有效解决目前自动驾驶测试数据的场景提取方法存在提取种类较少、自动化程度较低的问题,取得使场景提取种类更加全面、降低自动驾驶测试难度的效果。
