Alignment guide system for container

Abstract

The invention relates to an alignment guide system for a container. The guide system is characterized by comprising a container image acquisition module, a central processor module and an alignment information display module, wherein the container image acquisition module comprises cameras located at the four corner parts of a lifting appliance, and the images of the four corner parts of the container are shot by the cameras separately; the central processor module is used for identifying the target lock hole positions of the four corner parts of the container according to the images of the four corner parts, which are shot by the four cameras, and calculating the difference between the target lock hole positions and the current position of the lifting appliance; and the alignment information display module is used for displaying the target lock hole positions and the difference between the target lock hole positions and the current position of the lifting appliance, which are acquired by the central processor module, and tracking correction is carried out by operating personnel according to the displayed information. Compared with the prior art, the guide system disclosed by the invention has the following advantages: the defects of low accuracy and high random error of a single-point laser device, and high calculation quantity and high price of a three-dimensional laser device are avoided; and the guide system is high in accuracy, simple and convenient to operate, and reasonable in price during arrangement and execution.

Description

technical field [0001] The invention relates to a container-to-container guiding system. Background technique [0002] Existing devices for guiding the spreader to the container during loading or unloading, such as: [0003] Patent Publication No. CN 103196434A discloses a port container positioning device. By installing two laser ranging sensors on the horizontal plane of the carrier, the deviation information of the container position on the ground is measured, thereby assisting the positioning and loading and unloading of the container. [0004] Since the above-mentioned positioning device uses a small number of laser ranging sensors and uses single-point scanning, it has the disadvantages of low precision and high random error, and it is difficult to realize unmanned automatic box alignment in practical applications. [0005] Patent Publication No. CN 104085794A discloses an intelligent detection system and method for the distribution profile and position of containers....
