The invention discloses a visual detection device for automatic container placing of a container truck, which is characterized in that a network camera is mounted on a rail-mounted gantry crane to acquire video information of container placing operation in real time, the network camera is in signal connection with a video analysis server and a rail-mounted gantry crane PLC (Programmable Logic Controller) through a signal receiving and transmitting module, and the video analysis server receives image information of the network camera and transmits the image information to the rail-mounted gantry crane PLC; the method comprises the following steps: acquiring a target image, compressing, coding, transmitting, preprocessing, positioning, segmenting and matching to realize identification and analysis of the target image, acquiring multi-dimensional space information of a container through a network camera in a falling process of the container, calculating the offset of a lifting appliance in a current rail-mounted gantry crane position state through the space information by a video analysis server, and displaying the offset of the lifting appliance in the current rail-mounted gantry crane position state. And the PLC of the rail-mounted gantry crane performs dynamic deviation correction according to the offset, and finally the box placing process is completed. The container hole and the container truck lock pin can be accurately and automatically aligned, position deviation information can be sent to the ASC-PLC, the full-automatic container placing success rate of container truck container placing is achieved, and the port automation work efficiency is improved.
本发明公开了一种用于集卡自动放箱的视觉检测装置,网络摄像机安装于轨道吊实时获取放箱作业的视频信息,网络摄像机经由信号收发模块完成与视频分析服务器和轨道吊PLC的信号连接,视频分析服务器接收网络摄像机的图像信息,并进行压缩、编码、传输、预处理、定位分割、匹配,实现对目标图像的识别分析,集装箱下落过程中通过网络摄像机获取集装箱多维度空间信息,视频分析服务器通过空间信息计算当前轨道吊位置状态下吊具偏移量,轨道吊PLC根据偏移量进行动态纠偏,最终完成放箱过程;实现集装箱孔与集卡锁销精确自动对准,并能向ASC‑PLC发出位置偏差信息,实现对集卡放箱的全自动作业放箱成功率,提升港口自动化工作效率。
