Embodiment Construction

[0037] The specific implementation method of the internal truck positioning method will be described in detail below in conjunction with the embodiments. It should be understood that the specific examples described here are only used to explain the present invention, not to limit the present invention.

[0038] like Figure 1-7 As shown, a kind of internal collecting card location method based on painted block of the present invention, concrete steps are as follows:

[0039] Step 1: Paint a rectangular color block on the center of the trailer front and rear of the internal truck;

[0040] Step 2: Use the industrial camera on the spreader to collect the image of the head position of the internal truck;

[0041] Step 3: Convert the image in step 1) into a grayscale image, where the height of the image is height, the width is width, and the unit is pixel. The processing result refers to figure 1 ;

[0042] Step 4: Use the structural element with a core of 3*3 to perform media...

Abstract

The invention discloses a painted block-based internal container truck positioning method. According to the method, a container truck is positioned through identifying a painted block by utilizing a computer vision technology; and compared with a conventional manual operation, the method has the advantages that the positioning problem of the internal container truck is solved by using the computer vision technology, a container loading and unloading work mode based on manual guidance is improved, the container truck can be guided accurately and timely, the loading and unloading efficiency of containers can be greatly improved, the automation of loading and unloading the containers at a wharf is further realized, a large amount of manpower costs are reduced, and the method is a multi-win project for improving production and work environments.

Description

technical field [0001] The invention relates to a method for locating a collection card by using computer vision technology, in particular to an internal collection card positioning method based on a colored block for locating a collection card by identifying a colored block. Background technique [0002] With the rapid increase of port cargo throughput, the operating time of ships in the port is required to be shorter and shorter, and the requirements for the loading and unloading efficiency of port containers are getting higher and higher. In the port, internal container trucks (hereinafter referred to as internal container trucks) are the bridge connecting the yard and the ship. Therefore, how to improve the operating efficiency of the internal container trucks in the yard has become an important issue. [0003] In order to improve placement efficiency, some domestic ports have been trying to use new positioning methods, wherein the technical solutions closer to the prese...
