Real-time tracking and identifying method and device for steel coil loosening

Abstract

The invention discloses a real-time tracking and identifying method and device for steel coil loosening, and the method comprises the steps: adjusting a camera, and completing the setting of the initial position and the initial size of a hoisted steel coil; obtaining a video frame, and calculating the accurate position of the hoisted steel coil according to the initial position information; calculating the accurate size of the hoisted steel coil in the video frame according to the initial size information; intercepting a hoisting steel coil image in the video frame according to the accurate position and the accurate size of the hoisting steel coil, and identifying the hoisting steel coil; whether the coil is loosened or not is judged according to an identification result; judging whether the camera needs to be adjusted; acquiring a new video frame, tracking the hoisted steel coil, and determining the accurate position and the accurate size of the hoisted steel coil; and sending out a steel coil loosening alarm, and sending parking instruction information to a sharing area of the crown block hoisting system. According to the method, manual routing inspection and decision making are replaced, the steel coils hoisted by the crown block are tracked in real time, the steel coils with scattered outer sides and scattered strip steel heads are automatically recognized, and therefore automatic routing inspection and intelligent decision making of the steel coils in the storehouse in the hoisting process are achieved.

Description

technical field [0001] The invention relates to the technical field of pattern recognition, in particular to a method and device for real-time tracking and recognition of uncoiled steel coils. Background technique [0002] Coil slack is an appearance defect that poses a safety hazard. Loose coil is a kind of defect in the appearance of the strap fracture caused by the external force of transporting and moving the steel coil or the strap cannot withstand the tension of the steel coil. These uncoiled steel coils may cause the steel coils to scatter from the air and cause major production safety accidents during the crane hoisting process of storing or taking them away from the warehouse. [0003] At present, during the hoisting process of the steel coils in the warehouse, special staff are assigned to conduct on-site inspections to find out the uncoiling problems of the steel coils. However, on the one hand, manual inspections may not be found in time, and there are differen...
