Embodiment 1

[0034] The automatic recognition method of the handwritten slab number in this embodiment includes main steps 9 such as image pickup, storage, image conversion, image enhancement, denoising, binarization, character segmentation, feature vectorization, and character recognition (see figure 1 ). The specific process is as follows:

[0035] Image acquisition and storage—take images of slab numbers with the help of cameras; use hard disk video recorders and other storage devices to store the captured images of slab numbers to be identified, and store handwriting characteristics corresponding to different writers based on the statistics of the actual situation of the writers on the spot The height-to-width ratio of the characters and make it correspond to the corresponding character data information reflecting its writing characteristics. This statistics can be carried out continuously, so that the stored content can be continuously enriched and improved through learning and traini...

Abstract

The invention relates to a method and a corresponding device for automatically recognizing number symbols. The method comprises the following steps: shooting images of plate blank numbers, storing character height-width ratio corresponding to different character data information, and processing the shot images of the plate blank numbers, wherein the step of processing the images comprises image conversion, image enhancement, denoising, binarization, character segmentation, extraction of characteristic quantity, and character recognition. The method and the device not only adopt various effective measures to remove interferences so as to clarify the image according to the characteristics of field handwritten characters, but also grasp that each writing handwriting has the characteristic of specific rule character height-width ratio, and after performing necessary treatments on the character images, the method and the device transfer the pre-statistical character height-width ratio according to the treatment results to perform reasonable segmentation so as to ensure the accuracy of subsequent recognitions. Thus, the method and the device solve the bottleneck problems appearing in the full-automatic productions of iron and steel enterprises, and improve the production efficiency and the management level.

Description

technical field [0001] The invention relates to an automatic recognition method for number symbols, in particular to a method for automatic recognition of online handwritten slab numbers in the fields of steel manufacturing and the like, and a corresponding recognition device. Background technique [0002] With the continuous improvement of steelmaking and hot rolling production automation and the increasing pace of production, one of the bottleneck problems in fully automatic production is the identification of handwritten slab numbers. The backward manual identification method seriously hinders the production capacity. improvement. [0003] According to investigations, at present, iron and steel enterprises adopt manual methods for identifying slab numbers, that is, 24-hour manual guarding, identifying the slab numbers of the production line with naked eyes, and manually entering the corresponding monitoring system for verification. This not only greatly reduces the identi...
