Abstract

The invention discloses a steel coil lifting device automatic identification device and method adopting machine vision. The steel coil lifting device automatic identification device comprises a manipulator and CCD cameras installed on the manipulator. The CCD cameras are connected with a main control computer through an image capture card. A manipulator movement control system is installed on the main control computer and controls the manipulator to do corresponding movement through a control instruction. Edge characteristics of a steel coil is extracted through a vision image processing algorithm of the manipulator, and spatial position information of a target object is described through obtained image edge characteristic coordinate values. The manipulator movement control system establishes a dynamics simplified model of a mechanical lifting device to plan an operating path of the lifting device so that the lifting device can grab the target object automatically and fast. According to the steel coil lifting device automatic identification device and method, through machine vision technology, automatic and precise locating of the lifting device is achieved, all links of the lifting device do not need to be controlled manually, the requirement for an operator is low, the operation efficiency of a crane is high, and production benefits of customers and manufacturers can be increased to a great extent.

Description

technical field [0001] The invention relates to the field of automatic steel coil handling and lifting equipment, in particular to an automatic identification device and method for steel coil cranes using machine vision. Background technique [0002] When the steel mill moves steel coils, the operators use the workshop crane to complete the work, while the steel coils are grabbed by the spreader or mechanical arm installed on the crane. The spreader grabs objects is a complicated process. In the process of taking steel coils, the most critical technology is to control the spreader to accurately locate the position of the steel coils to complete the grabbing action. At present, the steel coil grabbing systems that have been put into use in the world generally require an experienced operator to remotely and manually control the manipulator spreader in order to achieve the purpose of precise positioning of the manipulator or spreader. The requirements for the operator are very...
