Abstract

The invention discloses a robot disordered grabbing method and system based on machine vision. The method comprises the steps that a kinect camera and a grabbing system of a robot are built, the kinect camera is used for collecting image data of the surface of a target object, and the image data are preprocessed to obtain three-dimensional point cloud data; target detection, target segmentation, target clustering, key point feature extraction, feature registration and target object recognition are performed on the acquired three-dimensional point cloud data to obtain pose information of the target object; and according to the calibration result of the hand-eye system, coordinate conversion is carried out on the pose information, and a control instruction is sent to a robot to grab the target object. By analyzing the defects of the algorithm in the disordered grabbing process of the robot and improving the existing algorithm, the complex environment where the robot is located is adapted, and therefore the disordered grabbing accuracy of the robot and the flexibility of the robot are improved.

Description

technical field [0001] The invention relates to the technical field of robot vision systems, in particular to a method, system and storage medium for 3D disorderly grasping. Background technique [0002] With the rapid expansion of the robot market and the rapid maturity of robot technology, the industrial robot industry has ushered in unprecedented opportunities for development. The original human-oriented production model has gradually changed to a production model dominated by industrial robots. The extensive use of industrial robots has promoted the rapid transformation of my country's industry from a "manufacturing power" to a "smart manufacturing power". [0003] However, in the process of robot operation, how to accurately grasp the randomly stacked parts or goods has become a hot issue in current research. In the existing technology, most of the robots on the production line realize various operations through teaching and reproduction or pre-programming. To complete...
