[0032] Please refer to figure 2 , figure 2 A flow chart of a method for detecting the position of a container provided by an embodiment of the present invention is shown. The container position detection method includes the following steps:

[0033] Step S1, acquiring a container image including at least one container, wherein each container includes identification information.

[0034] In the embodiment of the present invention, the container image may be a grayscale image including at least one container. It can be understood that the image of the container may include one container, two containers, or three containers. boxes, or more boxes. The crates are the same type of crates. The container image can be captured by the camera 106 in real time. The container image can be as image 3 shown. Each container contains identification information, and the position of the identification information relative to each container is fixed. The identification information may ...

Abstract

The invention relates to the technical field of image processing, and provides a container position detection method and device, and the method comprises the steps: obtaining a container image comprising at least one container; performing rotation matching on the container image and a pre-stored target template containing identification information to obtain matching information; screening out atleast one target matching coefficient from a plurality of matching coefficients corresponding to the at least one matching region; obtaining a target matching area and a target rotation angle corresponding to each target matching coefficient; and obtaining feature information of each container in the container image according to the at least one target matching area, the target rotation angle corresponding to the target matching area, and pre-stored relative position information of the identification information and the containers. Compared with the prior art, the container position detectionmethod and device provided by the invention can accurately identify the contour of the container to determine the position and direction of the container, thereby improving the efficiency of sorting operation.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image processing, and in particular, to a method and device for detecting the position of a container. Background technique [0002] Containers are a commonly used packaging method for manufacturers. In the warehousing and logistics link, containers are often classified into stacks and put on pallets according to varieties and specifications to facilitate storage and handling. When the container needs to be turned over or shipped out, with the popularization of mechanization and automation equipment, more and more enterprises use industrial robots, multi-degree-of-freedom motion platforms supplemented by manipulators or suction cups to sort and transport goods. [0003] When the manipulator or suction cup sorts the boxes in the stack, the control system needs to obtain the specific position and direction information of each item in the stack before controlling the mechanized equ...
