Abstract

The embodiment of the invention belongs to the field of image processing, is applied to the field of smart enterprises or smart government affairs of smart cities, and relates to a needle type printing character image generation method, which comprises the following steps: receiving a character image generation request which comprises a character string; selecting at least one picture from a preset picture library as a background image according to the character string; based on the background image, the character string and the font file, character image synthesis being carried out in a detection resampling mode, and an initial image being obtained; and performing disturbance processing on the initial image through a moving least square method to obtain a target needle type printing character image. The invention further provides a needle type printing character image generation device, computer equipment and a storage medium. In addition, by adopting the method, the technical problem that in the prior art, for character printing distortion caused by paper unevenness, the generated needle type printing character image cannot meet the requirement of model training is solved.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a method, device, computer equipment and storage medium for generating a dot-dot printing character image. Background technique [0002] Most of the text on invoices and other bills is printed by dot matrix printers. Compared with laser and thermal printing fonts, the murals of fonts are composed of fine dots, which are quite different from traditional text images and difficult to recognize. What's more, due to the unevenness of the invoice paper, the image degradation of the text printed by the dot matrix printer on the uneven paper is more serious. This makes the computer less effective in recognizing the character image. In order to recognize such text images, it is often necessary to manually label existing samples for training the recognition model. However, manually labeling dot-printing is expensive, slow, and has limited samples. In order to supplement the lac...
