The invention discloses a driving safety early warning system based on vision. The driving safety early warning system comprises a camera; the camera is used for taking pictures in the vehicle; the crowding degree module is used for extracting information of the received pictures and analyzing and determining passenger center point positions in the pictures; measuring the distance value of each passenger hollow point, then summing all the obtained distance values by S, and dividing the sum by the total passenger number A to obtain a crowding degree value F; the analysis module is used for analyzing and comparing the crowding degree value with a preset value; the level judgment module is used for judging the congestion level of an input passenger information image; the control module obtains the actual running speed of the vehicle obtained by the analysis module and sends a signal of the actual running speed of the vehicle to the accelerator alarm to remind a driver of controlling the speed of the vehicle. According to the crowding degree, adjustment and early warning are conducted in time on the running speed of the vehicle and distribution of people in a compartment, and therefore in the running process, the driving speed of the vehicle is improved. And the safety of personnel in the carriage is ensured.

    本发明公开了一种基于视觉的行车安全预警系统,包括摄像机;摄像机,用于拍摄车内的照片;拥挤度模块,对接收到的照片进行信息提取并分析确定照片中乘客中心点位置;测量每个乘客空心点的距离值,然后对所有得到的距离值进行求和S,再除以总乘客数量A,从而得到拥挤度值F;分析模块,将拥挤度值与预设值进行分析比较;用于判断输入乘客信息图像所处的拥挤度等级;控制模块,获取分析模块所得到的车辆实际行驶的速度,并将车辆实际行驶速度的信号发送给油门报警器,来提醒驾驶员对车辆速度的控制,本发明根据拥挤度对车辆的行驶速度和车厢内人员分布及时做出调整和预警,从而在行驶过程中,保证车厢内人员的安全。
