Express Waybill Recognition System Based On Deep Learning

In recent years,with the rapid development of the domestic e-commerce economy,the express delivery industry,which is an important support for e-commerce,has maintained rapid growth.Express delivery enterprises need to continuously improve their production intelligence and automation levels to meet the needs of business development.The detection and recognition of express delivery orders is an important link in achieving intelligence and automation in express delivery enterprises.By scanning the barcode information on the courier manifest,it is possible to quickly and accurately match the courier package with the user’s information,achieving automated inbound and outbound processing of the courier package.This paper designs a courier waybill recognition system based on deep learning Transformer,which is divided into two parts: barcode positioning and barcode decoding.The barcode positioning part uses Swin-Transformer to extract feature maps of different levels of the express delivery order,and then inputs the feature maps into Deformable Detr for feature fusion and decoding,thereby obtaining the bounding box of the barcode in the express delivery order.This algorithm uses the Transformer network structure for feature extraction,feature fusion,and target decoding,fully utilizing the Transformer’s global perception ability and strong universal modeling ability.At the same time,this algorithm belongs to a one-stage object detection algorithm,which can conduct end-to-end training and achieve joint optimization of network parameters.The barcode decoding section includes horizontal rotation and decoding.The horizontal rotation algorithm uses Hough transform to detect the lines in the barcode,and then calculates the tilt angle of the barcode,and then uses affine transformation to rotate the barcode to the horizontal position.This article uses morphological methods to process barcode images,improving the performance of Hough transform detection.For barcodes rotated to the horizontal position,this paper uses Open CV to decode Code-128 and obtain the corresponding tracking number of the barcode.Based on barcode positioning and decoding algorithms,this paper designs and implements an Android platform based express waybill scanning system.Users can use handheld devices to scan express waybill codes,and thus achieve inbound and outbound operations.
