基于深度学习的银行卡号识别研究

Research on Identification of Bank Card Number Based on Deep Learning

摘要: 针对自然环境下银行卡卡号识别困难等问题，本文提出了一种基于深度学习的银行卡卡号识别方法。方法分为两步：银行卡卡号区域定位和定位后的卡号识别。卡号区域定位使用CTPN神经网络训练的数据模型，训练集数据采用ICDAR2015；对定位的银行卡号，使用CRNN神经网络训练数据模型，最后完成卡号数字识别。本方法采用端到端对银行卡卡号行定位、识别，能够自动适应图片的倾斜，对自然环境下银行卡卡号的识别具有很好的适应性。

Abstract: In view of the difficulty in the identification of bank card numbers in natural environment, this paper proposes a method for the identification of bank card Numbers based on deep learning. The method is divided into two steps: the location of the bank card number and the identification of the card number after location. The data model of CTPN neural network was used for the location of card number area, and ICDAR2015 was used for the data of training set. The CRNN neural network was used to train the data model to locate the bank card number, and finally the card number digital recognition was completed. This method adopts end-to-end positioning and recognition of the bank card number line, which can automatically adapt to the tilt of the picture, and has good adaptability to the identification of bank card number in natural environment.
