摘  要:针对票据在识别时出现数据漏检率高、识别精度低的问题,提出文本检测模型ENCRAFT与识别模型DLCNN。在文本检测模型CRAFT的基础上,ENCRAFT修改其原始的特征提取网络的结构,利用未经池化的特征图进行融合,减少了细小特征的丢失,并增大监督特征图的分辨率,以提供更丰富的监督信息,从而提高模型检测率;DLCNN利用深层的卷积网络与浅层的循环网络实现对中文票据的高精度识别。实验结果表明,该方法在多个票据数据上的检测率与识别精度均有明显提升。There are problems of high data leakage rate and low recognition accuracy in the recognition of bills.Aiming at these problems,the text detection model ENCRAFT and the recognition model DLCNN were proposed.Based on the text detection model CRAFT,ENCRAFT is used to modify the structure of its original feature extraction network,and fuse the feature map without pooling.In the DLCNN model,the loss of fine features is reduced,and the resolution of the supervisory feature map is increased to provide richer supervisory information,so as to improve the model detection rate.A deep convolutional network and a shallow recurrent network were atilized to achieve high-precision identification of Chinese tickets.Experimental results show that the detection rate and recognition accuracy of the proposed method on multiple ticket data are significantly improved.
