The invention provides a vehicle collision early warning and processing method and device based on ultrasonic waves and 3D look-around, and the method comprises the steps: obtaining ultrasonic signal data which comprises an ultrasonic reflection signal which is transmitted by a vehicle and is reflected by an obstacle; carrying out filtering processing on the ultrasonic reflection signal; obtaining a distance early warning level based on a preset first judgment model; in response to recognition of the obstacle in the preset early warning area, outputting a warning signal to a driver, judging the direction of the obstacle, and obtaining direction information of the obstacle; acquiring original image data around the vehicle, and establishing a 3D looking-around model of the vehicle; and switching to a 3D look-around virtual camera visual angle matched with the obstacle direction information. According to the invention, the visual angle of the 3D look-around virtual camera can be automatically switched according to the direction of the obstacle, and the safety in the vehicle driving process is improved.

    本发明提供了基于超声波和3D环视的车辆碰撞预警及处理方法、装置,其方法包括:获取超声波信号数据,包括由车辆发出并经障碍物反射的超声波反射信号;对超声波反射信号进行滤波处理;基于预设第一判断模型获取距离预警等级;响应于预设预警区域内障碍物的识别,向驾驶员输出警示信号,进行障碍物方向判断,获取障碍物方向信息;获取车辆周围的原始图像数据,建立车辆的3D环视模型;切换至与所述障碍物方向信息匹配的3D环视虚拟相机视角。本发明实现了3D环视虚拟相机视角根据障碍物方向进行自动切换,提升了车辆驾驶过程中的安全性。
