Method for collecting and extracting behavior of vehicle passing through curve

The invention provides a method for collecting and extracting behaviors of a vehicle passing through a curve. The method comprises the following steps: S1, obtaining vehicle information; s2, marking a curve passing behavior scene according to comparison between the acquired vehicle information and a set threshold value; s3, the curve behavior scene of the mark is judged, and whether the curve behavior scene of the mark conforms to a specified curve scene or not is judged; and S4, if the curve behavior scene is met, curve scene fragments are extracted. According to the method for collecting and extracting the behaviors of the vehicle passing through the curve, the behavior scenes can be automatically recognized and extracted in batches, the extraction efficiency of the behavior scenes is effectively improved, and the behavior scene requirements of development are met. 本发明提供了一种车辆通过弯道的行为采集提取方法，包括以下步骤：S1、获取车辆信息；S2、根据获取的车辆信息与设定阈值的对比，对通过弯道行为场景进行标志；S3、对标志的弯道行为场景进行判定，判定标志的弯道行为场景是否符合规定的弯道场景；S4、若符合弯道行为场景，则对弯道场景片段进行提取。本
