The invention provides a license plate recognition method, electronic equipment, a license plate recognition system and a computer readable storage medium. The method comprises the following steps: successively acquiring two first images containing a target vehicle at a first moment and a second moment by using a first camera in a preset area; predicting position information of the target vehicle at a preset moment based on the two first images, wherein the preset moment is a moment after the second moment; determining a target focal length of a second camera based on the position information of the target vehicle at a preset moment; the focal length of the second camera is adjusted to be the target focal length, and a second image of the target vehicle is obtained through the second camera at the preset moment; and based on the second image, identifying the license plate of the target vehicle to obtain license plate information of the target vehicle. The license plate information of the muck truck can be recorded when the muck truck works or runs, the license plate recognition accuracy is high, the intelligent degree is high, and the working efficiency is improved.

    本申请提供了车牌识别方法、电子设备、系统及计算机可读存储介质,该方法包括:利用预设区域的第一摄像头在第一时刻和第二时刻先后获取包含目标车辆的两个第一图像;基于两个第一图像预测预设时刻的目标车辆的位置信息,预设时刻是第二时刻之后的时刻;基于预设时刻的所述目标车辆的位置信息,确定第二摄像头的目标焦距;将第二摄像头的焦距调整为目标焦距,并在预设时刻利用第二摄像头获取目标车辆的第二图像;基于第二图像,对目标车辆的车牌进行识别,以得到目标车辆的车牌信息。本申请能在渣土车作业或行驶的状态下,记录渣土车的车牌信息,车牌识别准确率高,智能化程度高,提高工作效率。
