The invention discloses a commercial vehicle driver portrait classification method based on vehicle-mounted video identification, and the method comprises the steps: collecting data, and generating an active safety early warning information detailed data table; generating an overtime fatigue driving record table; extracting an early warning record corresponding to each driver, and generating an early warning frequency record table; key data in the early warning video record data are extracted, and evaluation indexes are calculated; calculating the lane offset; and according to the evaluation index and the lane offset, depicting the reaction degrees of the drivers under different early warning types, and obtaining classification results of the drivers under different early warning types. According to the invention, the driving behavior of the driver is described by deeply extracting the video information, the driver is classified according to the driving behavior, and the driving characteristics of the driver can be efficiently and accurately captured through the vehicle-mounted real-time video; powerful theoretical support can be provided for establishing a driving safety evaluation system of key operating vehicles by classifying driving behaviors and analyzing user portraits.

    本发明公开了一种基于车载视频识别的营运车辆驾驶员画像分类方法,包括:采集数据,生成主动安全预警信息详细数据表;生成超时疲劳驾驶记录表;提取每一位驾驶员对应的预警记录,生成预警次数记录表;提取预警视频记录数据中的关键数据,计算评价指标;计算车道偏移量;根据评价指标和车道偏移量刻画驾驶员在不同预警类型下的反应程度,得到不同预警类型下驾驶员的分类结果。本发明通过对视频信息的深入提取刻画驾驶员的驾驶行为,根据驾驶行为对驾驶员进行分类来,通过车载实时视频,可以高效准确的捕捉驾驶员的行车特征,对驾驶行为归类、用户画像分析可以为重点营运车辆的行车安全评价体系的建立提供有力理论支撑。
