The invention relates to a real-time curve rollover early warning system and method based on a binocular camera, and belongs to the technical field of automobile active safety control; the system comprises an image acquisition module which is used for collecting images of a straightway and a curve in real time; an image processing module which is used for processing the image in real time, identifying a road, judging whether a curve is in front or not, calculating the curvature of the curve, and finding out curve feature points through a binocular camera to measure the distance of the curve; a detection module which is used for measuring the speed, the roll angle and the roll angle speed of the measured vehicle; an information processing module which is used for integrating the information and processing the information. a display module which is used for displaying the front road information transmitted by the information processing module in real time and carrying out voice reminding on a driver. The system can detect the front road information in real time and obtain the critical speed of the vehicle passing through the curve in combination with the detection module, so that a driver who is about to enter the curve can be early warned, and the road driving safety is improved.
本发明涉及一种基于双目相机的实时弯道侧翻预警系统与方法,属于汽车主动安全控制技术领域,包括图像获取模块,用于实时采集直道与弯道的图像。图像处理模块,用于对图像进行实时处理,对道路进行识别,判断前方是否为弯道,算出弯道曲率,并通过双目相机找出弯道特征点对弯道进行测距。检测模块,用于测量被测车辆的速度、侧倾角、侧倾角速度。信息处理模块,用于整合各项信息,并对各项信息进行处理。显示模块,用于对信息处理模块传来的前方道路信息进行实时显示,并对驾驶员进行语音提醒。该系统能够实时检测前方道路信息,并结合检测模块得出车辆通过弯道的临界速度,从而能够给即将进入弯道的驾驶员进行预警,提高了道路行车的安全性。
