The invention discloses a vehicle information acquisition method and device, equipment and a medium, and belongs to the technical field of computers, and the method comprises the steps that N first shooting sets corresponding to N theoretical shooting distances are acquired, and the first shooting sets comprise second shooting sets of a plurality of actual shooting distances; identifying the shooting information to obtain a license plate identification result; obtaining a plurality of first errors of each theoretical shooting distance based on license plate recognition results of all shooting information in each second shooting set; determining an error influence value corresponding to each theoretical shooting distance based on the plurality of first errors of each theoretical shooting distance; and determining the theoretical shooting distance with the minimum error influence value as a target theoretical shooting distance, and shooting the vehicle based on the target theoretical shooting distance to obtain target shooting information. According to the embodiment of the invention, the quality of license plate shooting information and the license plate recognition accuracy can be improved.

    本申请公开了一种车辆信息获取方法及其装置、设备及介质,属于计算机技术领域,包括:获取N个理论拍摄距离对应的N个第一拍摄集合,第一拍摄集合包括多个实际拍摄距离的第二拍摄集合;对拍摄信息进行识别,得到车牌识别结果;基于每个第二拍摄集合中所有拍摄信息的车牌识别结果,得到每个理论拍摄距离的多个第一误差;基于每个理论拍摄距离的多个第一误差,确定每个理论拍摄距离对应的误差影响值;确定误差影响值最小的理论拍摄距离为目标理论拍摄距离,以基于目标理论拍摄距离对车辆进行拍摄,得到目标拍摄信息。根据本申请实施例,能够提升车牌拍摄信息的质量,以及车牌的识别准确率。
