The embodiment of the invention discloses a method and system for displaying a reversing image, and relates to the technology of vehicle inforams.The method comprises the steps that when an MCU detects that a vehicle is in a reverse gear state, the current distance between the vehicle and an obstacle behind the vehicle and the current turning angle of a steering wheel are detected; the reverse gear state, the current distance and the current steering angle of the steering wheel are transmitted to the video processor; the video processor reads a reversing auxiliary line picture corresponding to the current turning angle of the steering wheel from the memory; if the current distance is smaller than a set threshold value, the video processor intercepts the car-backing auxiliary line picture according to the current distance to obtain a target car-backing auxiliary line picture; and the video processor fuses the target reversing auxiliary line picture with the current vehicle rear image transmitted by the camera, generates a reversing image and displays the reversing image on the screen. According to the embodiment of the invention, the reversing image can be flexibly and quickly displayed according to the distance between the vehicle and the obstacle behind the vehicle.
本发明实施例公开了一种倒车影像的显示方法和系统,涉及车机技术,方法包括MCU检测到车辆处于倒挡状态时,检测所述车辆与车后障碍物的当前距离和方向盘当前转角,并将所述倒挡状态、当前距离和方向盘当前转角传输至所述视频处理器;所述视频处理器从所述存储器读取与所述方向盘当前转角对应的倒车辅助线图片;如果所述当前距离小于设定阈值,所述视频处理器根据所述当前距离对所述倒车辅助线图片进行截取,得到目标倒车辅助线图片;所述视频处理器将所述目标倒车辅助线图片与所述摄像头传输的当前车后影像进行融合,生成倒车影像并显示在所述屏幕上。本实施例可以根据车辆与车后障碍物之间的距离,灵活、快速地显示倒车影像。
