The invention relates to the field of vehicle distance measurement, and provides a vehicle distance measurement method and device and a vehicle, the basic information of a main target vehicle is determined according to a front view image, the target vehicle size of the main target vehicle is inquired in a vehicle database, the main target vehicle size is inquired through image recognition data, and a basis is provided for image distance measurement. And determining a first target distance of the main target vehicle according to the camera internal reference, the basic information and the size of the target vehicle to realize image distance measurement. And determining a second target distance of the main target vehicle according to the radar information of the main target vehicle to realize radar ranging. The first target distance and the second target distance are fused to obtain the final target distance relative to the main target vehicle, fusion of the image ranging result and the radar ranging result is achieved, and the result is more reliable and accurate.

    本发明涉及车辆测距领域,提供一种车辆测距方法、装置和车辆,根据前视图像确定主目标车辆基础信息,在车辆数据库中查询主目标车辆的目标车辆尺寸,实现图像识别数据查询主目标车辆尺寸,为图像测距提供基础。根据摄像头内参、基础信息和目标车辆尺寸,确定主目标车辆第一目标距离,实现图像测距。根据主目标车辆的雷达信息,确定主目标车辆第二目标距离,实现雷达测距。根据第一目标距离和第二目标距离进行融合,得到相对主目标车辆的最终目标距离,实现图像测距和雷达测距结果的融合,结果更加可靠和准确。
