The invention provides a vehicle anti-collision early warning method based on machine vision. The vehicle anti-collision early warning method comprises the following steps that S1, image data of a front road are collected through a camera in an image collection module; s2, preprocessing the acquired image data through an image processing module; s3, carrying out obstacle recognition on the preprocessed image data based on an obstacle recognition module, and determining the position and speed of an obstacle; s4, calculating a collision risk index through a risk assessment module; and S5, when the collision risk index exceeds a preset threshold value, an early warning module sends out an anti-collision early warning signal. According to the vehicle anti-collision early warning method based on machine vision, real-time detection of obstacles in front of the vehicle and dynamic evaluation of collision risks are achieved, risk collision indexes are evaluated through the risk evaluation module, and the safety distance threshold value is dynamically adjusted according to the current speed of the vehicle and road conditions.

    本发明提供了一种基于机器视觉的车辆防碰撞预警的方法,包括以下步骤:步骤S1、通过图像采集模块中的摄像头采集前方道路图像数据;步骤S2、通过图像处理模块对采集到的图像数据进行预处理;步骤S3、基于障碍物识别模块对预处理后的图像数据进行障碍物识别,并确定障碍物的位置和速度;步骤S4、通过风险评估模块计算碰撞风险指数;步骤S5、当碰撞风险指数超过预设阈值时,预警模块发出防碰撞预警信号。本发明采用上述的一种基于机器视觉的车辆防碰撞预警的方法,实现了车辆前方障碍物的实时检测和碰撞风险的动态评估,通过风险评估模块进行风险碰撞指数的评估,并且安全距离阈值根据车辆的当前速度和道路条件动态调整。
