Target tracking sorting system on conveyor belt

Abstract

The invention relates to a moving target tracking sorting system on a conveyor belt. The moving target tracking sorting system comprises a pickup camera and a robot and further comprises an image capture thread, an image processing thread and a mechanical arm motion control thread, wherein the pickup camera is connected onto a camera; the robot is provided with a controller and a mechanical arm; the image capture thread is responsible for capturing images shot by the pickup camera and sending each captured frame to the image processing thread; the image processing thread is responsible for receiving the images sent by the image capture thread, processing the images, obtaining a target position, calculating the target speed and updating the target position; and the mechanical arm motion control thread sends the position information of the target to the controller to enable the mechanical arm to grab the target. The moving target tracking sorting system can precisely track the target position to precisely grab the target with any size, reduces the total cost, and is multifunctional and flexibly applied.

Description

technical field [0001] The invention relates to an object tracking and sorting system on a conveyor belt, which includes a camera and a robot with a controller and a mechanical arm. Background technique [0002] The sorting of objects moving on the conveyor belt is an important link in logistics production. At present, most sorting systems use laser devices to detect whether the objects have reached the designated position, then stop the conveyor belt transportation, and notify the actuator, such as a robotic arm, to sort the objects. There are two disadvantages in this way of stopping the conveyor belt: slow operation speed of the whole system and frequent opening and stopping will shorten the life of the motor controlling the conveyor belt. [0003] An improved object sorting system on the conveyor belt, including a camera, a mechanical arm and a speed encoder, which uses the speed encoder to measure the belt speed of the conveyor belt, and uses the camera and the speed en...

AI Technical Summary

Problems solved by technology

This method of stopping the conveyor belt has two disadvantages: the slow operation speed of the entire system and frequent opening and stopping will shorten the life of the motor that controls the conveyor belt

However, due to the low accuracy and low stability of the speed encoder, this method has the defect of inaccurate target position tracking, especially for small targets, which is difficult to accurately track, so it can only be used for sorting large targets on the conveyor belt

[0004] From the sorting system of moving objects to the tracking and sorting system of moving objects, the status of the conveyor belt is changed from stop to non-stop. Although the work progress of the whole system has been accelerated, the existing object tracking and sorting system on the conveyor belt still exists. The above defects need to be improved urgently
