The invention provides a container number identification method and system and a reach stacker, and is applied to the technical field of engineering machine.The method comprises the steps that firstly, the current boom length of a boom of the reach stacker is obtained, the reach stacker is used for hoisting a container, and the boom of the reach stacker is provided with an image acquisition device; the method comprises the following steps of: acquiring the current boom length of a reach stacker, then adjusting a shooting angle of an image acquisition device based on the current boom length so as to enable a container to be located at a preset position of a to-be-identified image acquired by the image acquisition device, and adjusting a region of interest (ROI) corresponding to the to-be-identified image based on the current boom length so as to enable the ROI to comprise a container number. And the shooting angle of the image acquisition device and the ROI corresponding to the to-be-identified image are adjusted based on the current boom length, so that the container number to be identified is in the ROI, the container number which is being grabbed can be accurately identified by removing the interference characters, and the operation efficiency is improved.

    本申请提供一种集装箱箱号识别方法、系统及正面吊,应用于工程机械技术领域,该方法首先获取正面吊的臂架的当前臂架长度,正面吊用于吊运集装箱,且正面吊的臂架设置有图像采集装置,然后基于当前臂架长度调整图像采集装置的拍摄角度,以使集装箱处于图像采集装置采集的待识别图像的预设位置,以及,基于当前臂架长度调整待识别图像对应的感兴趣区域ROI,以使ROI中包括集装箱箱号,本方法获取正面吊的当前臂架长度,并基于当前臂架长度调整图像采集装置的拍摄角度和待识别图像对应的ROI,使得要识别的集装箱箱号在ROI中,通过去除干扰字符可以精准识别正在抓取的集装箱箱号,提高作业效率。
