Method for identifying steel coil information

Abstract

The invention relates to a method for identifying steel coil information, being characterized by comprising the following steps: determining the position coordinates of a coil number in the obtained steel coil image by using a minimum bounding rectangle method, and then converting the steel coil image state characteristics at the position coordinates into character values by using a convolutional neural network-based digital character classification mode, so that the character values are the coil number of the current steel coil; and using a temperature detection module to detect the temperature of the steel coil while obtaining a side face image of the steel coil, obtained by shooting through the camera, judging whether the roundness of the steel coil reaches the standard or not through the side face image by an upper computer, and transmitting the judgment result to the background. According to the method for identifying steel coil information, rapid identification of the steel coil is achieved; the scanning period is shortened; and the logistics efficiency is improved. The method for identifying steel coil information can accurately detect the information of the steel coil, is high in the detection speed, and has the characteristic of real-time performance.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method for identifying steel coil information. Background technique [0002] Automatic identification and positioning technology is one of the effective ways to make finished product warehouse intelligent and unmanned. Through intelligent detection and positioning, spreader transformation and automatic control technology, manual assistance will be greatly reduced, especially to avoid manual intervention in more dangerous operations . The finished product warehouse is an important logistics storage department of a steel company, and the loading and unloading operation of steel coils is a prominent link that affects logistics efficiency and safety. At present, most steel warehouses mainly use manual operation and monitoring methods in the transportation process of steel coils. In this way of working, there are potential safety hazards for workers, and the manual operation mainly...

Problems solved by technology

In this way of working, there are potential safety hazards for workers, and the manual operation mainly relies on the driver's naked eye observation, which has a certain degree of randomness, resulting in low work efficiency due to unnecessary start and stop of driving.

There are also a small number of steel warehouses with a high degree of automation that use lasers as sensors to assist in automatic identification and grabbing of steel coils. However, due to the long cycle of laser scanning steel coils, the production efficiency is low, so there is an urgent need for a method that can accurately identify steel coils. Coil information, reducing the scanning cycle, to better complete the identification and positioning of steel coils
