The embodiment of the invention relates to the technical field of intelligent driving, and particularly discloses a car following distance self-adaptive adjustment method and system based on face recognition. According to the embodiment of the invention, different driver ID information base files are generated by performing face recognition on a driver; pupil change parameters of the driver are analyzed and obtained, and the type of a front vehicle and the real-time vehicle following distance are comprehensively recognized; obtaining an opening state of a high-speed navigation function; when the high-speed navigation function is not started, constructing a vehicle following adjustment model; when the high-speed navigation function is started, according to the vehicle following adjustment model, the pupil change parameters and the expected vehicle following distance corresponding to the type of the front vehicle are obtained, and vehicle following distance adjustment is conducted according to the real-time vehicle following distance. After the high-speed navigation function is started, the adjustment of the vehicle following distance is closer to the vehicle following driving habit of the current driver, the intelligent driving experience is improved, the risk that surrounding vehicles jump a queue can be reduced to a certain extent, and the driving comfort and safety are improved.

    本发明实施例涉及智能驾驶技术领域,具体公开了一种基于人脸识别跟车距离自适应调节方法及系统。本发明实施例通过对驾驶员进行面部识别,生成不同的驾驶员ID信息库文件;分析获取驾驶员的瞳孔变化参数,综合识别前车类型与实时跟车距离;获取高速领航功能的开启状态;在高速领航功能未开启时,构建跟车调整模型;在高速领航功能开启时,根据跟车调整模型,获取瞳孔变化参数和前车类型对应的期望跟车距离,并按照实时跟车距离进行跟车距离调整。能够在高速领航功能开启后,跟车距离的调整更贴近于当前驾驶员的跟车驾驶习惯,提升智能驾驶体验,且能够从一定程度上降低了周围车辆插队的风险发生,提高了驾驶的舒适性和安全性。
