Abstract

The invention is applicable to the technical field of character recognition, and provides a verification code recognition method and device. According to the embodiment of the invention, the method comprises the steps: obtaining a to-be-tested verification code picture, and carrying out the segmentation of each character in the to-be-tested verification code picture according to a first connected domain in the to-be-tested verification code picture, and obtaining each character picture; determining a feature vector of each character picture, and inputting the feature vector of each character picture into at least two preset character classifiers to obtain an identification result of each character picture; and splicing the identification result of each character picture to obtain the identification result of the to-be-tested identification code picture, thereby improving the identification accuracy of the verification code.

Description

technical field [0001] The present application belongs to the technical field of character recognition, and in particular relates to a verification code recognition method and device. Background technique [0002] With the development of society, the emergence of automation technology has brought a lot of convenience to people's life and work. However, in automation projects such as web crawlers, often when the automation program performs network registration or login, it needs to input information on the current website. captcha, but only terminates the current automation job. Moreover, there is a lot of interference information in the verification code picture recognized by human eyes at present, which leads to the recognition error of some characters in the verification code picture, and then causes the verification code recognition accuracy to be low. Therefore, how to accurately identify the verification code information so as to facilitate the automatic registration o...
