The invention relates to the technical field of automobile safety, in particular to a blind area early warning method and system based on vehicle and road information fusion, and the method comprises the steps: obtaining the first distance information between an obstacle in a blind area and a vehicle according to the image data of the blind area of the vehicle; according to the radar data of the vehicle blind area, obtaining second distance information between an obstacle in the blind area and the vehicle; determining weight coefficients of the first distance information and the second distance information based on the atmospheric visibility of the position of the vehicle; according to the weight coefficients of the first distance information and the second distance information, the first distance information and the second distance information are processed, and the relative distance between the obstacle in the blind area and the vehicle is obtained; when the relative distance information is smaller than a preset threshold value, blind area early warning is conducted on the vehicle. According to the invention, position measurement and dual correction are carried out on the obstacle by combining image data and radar data, so that the distance measurement precision can be greatly improved, distance danger early warning can be accurately realized, and the driving safety is effectively ensured.
本申请涉及汽车安全的技术领域,尤其涉及一种基于车路信息融合的盲区预警方法及系统,方法包括:根据车辆盲区的影像数据,获取盲区内障碍物与车辆的第一距离信息;根据车辆盲区的雷达数据,获取盲区内障碍物与车辆的第二距离信息;基于车辆所在位置的大气能见度确定第一距离信息以及第二距离信息的权重系数;根据第一距离信息以及第二距离信息的权重系数,对第一距离信息以及第二距离信息进行处理,得到盲区内障碍物与车辆之间的相对距离;在相对距离信息小于预设阈值时,对车辆进行盲区预警。采用影像数据与雷达数据结合的方式对障碍物进行位置测量以及双重校正,从而能够大大提高测距精度,便于精确的实现距离危险预警,有效保证行车安全。
