The invention discloses an automatic container stacking system of a crane. The system comprises a pair of position detection units (10), an image processing unit (20) and a control unit (30). The position detection units can be arranged on a lifting appliance, and each position detection unit comprises a line laser (12) and a camera (14). The two line lasers can project laser light beams extending in the movement direction of the lifting appliance on the top surface of the container below a container grabbed by the lifting appliance. The cameras can correspondingly acquire image information containing laser light beams projected by the line lasers. The image processing unit is configured to calculate deviation distance information of the container grabbed by the lifting appliance. The control unit is configured to control a driving system to drive the lifting appliance to move according to the deviation distance information, so that the container grabbed by the lifting appliance is aligned with the container below. The algorithm of the automatic container stacking system of the crane is simpler and is not prone to being interfered by the environment on site. The invention further provides the crane with the control system.

    起重机的自动堆箱系统,包括一对位置检测单元(10)、一个图像处理单元(20)以及一个控制单元(30)。位置检测单元能够设置于吊具,各位置检测单元包括一个线激光器(12)和一个相机(14)。两个线激光器分别能够在位于吊具抓起的集装箱下部的集装箱的顶面投射沿吊具的运动方向延伸的激光光条。相机能够对应地获取含线激光器投射的激光光条的图像信息。图像处理单元配置为能够计算得出吊具抓起的集装箱的偏离距离信息。控制单元配置为能够根据偏离距离信息控制驱动系统驱动吊具运动,使吊具抓起的集装箱与下部的集装箱对齐。起重机的自动堆箱系统的算法更简单并且不易受到现场环境的干扰。本发明还提供了具有上述控制系统的起重机。
