Four or six digits, variable length, calculation questions and other verification codes can all be handled by one tool, which is simple and convenient and can be used out of the box, with an accuracy of up to 96%! !

Four or six digits, variable length, calculation questions and other verification codes, the accuracy rate of third-party platforms is low, and I don’t know how to train neural networks. !

This article adheres to the out-of-the-box principle, and truly achieves a tool to identify all single-line text verification codes in seconds. The single line here refers to a 4-digit 6-digit or calculation question or text verification code. I used 4 Digit + 6 digits + calculation questions, train recognition together, my data set part display picture is as follows:

There are probably so many types. If you have many types, you can put them all together for training. Not much to say, just look at the training steps

1. Download the training tool

There are actually a lot of deep learning training tools on the market, because they are out-of-the-box, and the final recognition effect must be ensured, so here I choose to use PaddleOCR for training
