Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0024] In the prior art, training a character recognition system requires a large amount of training pictures, which requires the training pictures to be diverse to simulate the authenticity of character recognition by the character recognition system in various scenarios.
[0025] figure 1 is a flow chart of a picture synthesis method provided by an embodiment of the present invention, such as figure 1 As shown, the method includes:
[0026] Step 101. Obtai...

The embodiment of the invention discloses a picture synthesis method and device and a character recognition system, and the method comprises the steps: obtaining original corpus information, and screening the original corpus information to obtain target corpus information for picture synthesis; segmenting the target corpus information to obtain a plurality of character sets, and selecting one target character set from the plurality of character sets; obtaining a font file, and selecting one font from the font file as the font of the target character set; obtaining a background picture, and selecting one background picture from the background pictures as the background picture of the target character set; calculating the sum of the distances between the clustering center of the background picture and the color numbers of the font colors of the target character set; taking the color of which the distance sum is greater than a set distance threshold value as the color of the target character set; and synthesizing the target character set and the background picture to obtain a synthesized picture. Richness and authenticity of the synthesized picture are improved.
Description
technical field [0001] The invention relates to the field of character recognition, in particular to a picture synthesis method and device, and a character recognition system. Background technique [0002] Due to the hugeness of Chinese characters in OCR text recognition, tens of millions of pictures are generally required to train a text recognition system. The data volume of training pictures has become an urgent problem for text recognition. If tens of millions of text pictures are manually marked, it will consume a lot of human and financial resources. In the OCR text recognition business scenario, there will be insufficient training pictures and lack of diversity in training pictures. Contents of the invention [0003] In order to solve the above problems, the embodiment of the present invention discloses a picture synthesis method and device, and a text recognition system, which can automatically generate diversified pictures for OCR text recognition. [0004] On th...
