The invention provides a front and back vehicle distance sudden change early warning method and early warning system and a storage medium, and the method comprises the steps: entering a vehicle distance detection mode when the vehicle driving speed meets a first preset condition; respectively acquiring image information of the camera end at a preset time interval Tms, and identifying a target vehicle in the image information by adopting a visual identification model; the camera end at least comprises a first camera and a second camera at the vehicle end; wherein T is a real number greater than zero; the contour area of the target vehicle is extracted, the driving state of the target vehicle is judged by calculating the change of the contour area, early warning is conducted on the current vehicle according to the driving state, and a safe distance is kept between the current vehicle and the vehicle on the same lane. According to the invention, sudden braking of the front vehicle or sudden approaching of the rear vehicle can be identified by detecting changes of the front and rear vehicles, and a driver is informed through the loudspeaker in the vehicle, so that a safe distance is kept between the current vehicle and the vehicle on the same lane.

    本发明方法提供一种前后车辆距离突变预警方法、预警系统和存储介质,所述方法包括:当车辆行驶速度满足第一预设条件时,进入车辆距离检测模式;分别获取摄像头端在预设时间间隔Tms的图像信息,采用视觉识别模型识别所述图像信息中的目标车辆;所述摄像头端至少包括:车辆端的第一摄像头和第二摄像头;其中,T为大于零的实数;提取所述目标车辆的轮廓面积,通过计算所述轮廓面积的变化判断所述目标车辆的行驶状态,根据所述行驶状态对当前车辆进行预警,使当前车辆与同车道车辆间保持安全距离。本发明能够通过检测前后车辆的变化,识别出前车急刹或者后车突然靠近,并通过车内扬声器告诉驾驶员,使当前车辆与同车道车辆间保持安全距离。
