Abstract

A method (100) of picking an object from a container (230) by a robot manipulator (211) is disclosed, and it includes obtaining a first image containing pixels representing greyscale information for the object (220) and the container (230); obtaining a second image containing pixels representing 3D spatial information for the object (220) and the container (230); identifying at least one surface of the object (220) in the first image based on the greyscale information; identifying pixels for the at least one surface of the object (220) in the second image based on the identified at least one surface of the object (220) in the first image and the 3D spatial information; and controlling, based on the identified pixels in the second image, the robot manipulator (211) to approach the identified at least one surface for picking the object (220). The device, system or method according to the present disclosure provides an improved solution for making the computing resources required by the image analysis less demanding. In addition, the processing speed will be greatly improved, and thus the picking motion of the robot manipulator (211) is fast and accurate.

Description

technical field [0001] Example embodiments disclosed herein relate generally to methods of picking objects from containers by robotic manipulators, and also to electronic devices for implementing the methods and systems for picking objects from containers. Background technique [0002] In logistics or other industries, robots are widely used to pick objects from larger containers. Typically, objects such as boxes are randomly placed in containers. Containers typically move on a conveyor belt, and the conveyor belt stops when the robotic manipulator is ready to pick a box from the container. [0003] Therefore, there is a need in the industry to be able to quickly pick boxes from containers so that the containers can be emptied in less time. After a container is emptied, the next container will be placed in place for the robotic manipulator to empty. Empty boxes in a container faster can lead to a significant increase in overall efficiency. [0004] Currently, 3D cameras ...
