Embodiment Construction

[0043] The express parcels that need to be sorted are divided into box-type express parcels and bag-type express parcels. Before sorting, the two types of parcel express parcels are separated and sent by two conveyors respectively. In this example, packaging box-type express mail is taken as an example, please refer to figure 1 In this embodiment, an express sorting system based on robot visual servoing technology includes a conveyor device 10, a first camera device 20, a second camera device 30, and a robot 40. The conveyor device 10 is provided with a A photographing area and a sorting area, the first photographing device 20 is located directly above the photographing area, the second photographing device 30 is located to the side of the photographing area, and the robot 40 is located on the conveying device 10 The end of the transmission device 10, the first camera 20, the second camera 30, the robot 40 can be connected via a network or a local area network. In this embodime...

Abstract

The invention relates to an express sorting method and system based on a robot visual servo technology. The method includes: acquiring a top view image and a side view image of an express; according to the top view image and side view image of the express, acquiring the coordinates of express peripheral points, the express affiliated area and the placement posture of the express on a conveyor, and letting the robot estimate the current position of the express; when the express enters a sorting zone, utilizing the estimated current position of the express and relevant parameters of the robot to adjust the position of a mechanical arm, shooting the two-dimensional image of the express in motion, positioning the express through the visual servo technology and calculating a discrete value; and controlling an end operation apparatus according to the discrete value to grab the express.

Description

Technical field [0001] The invention relates to the field of logistics automation, in particular to a method and system for express sorting based on robot visual servo technology. Background technique [0002] Generally, robots are widely used in electronic products, such as the automotive industry, plastics industry, pharmaceutical industry, and food industry. They are used to complete operations such as handling, assembly, spraying, welding, etc., instead of manual operations, thereby improving production efficiency . [0003] In the express industry, the sorting of express packaged goods is generally achieved manually. This operation method is inefficient and difficult to guarantee accuracy. Due to the large workload, employees often do not operate according to the standard and classify the items by throwing away. The items in the box are easily damaged. In addition, sorting operations require a large number of staff. With the increase in labor costs, the cost of express deliv...
