Embodiment Construction

[0020] The present invention will be further specifically described below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0021] figure 1 It is a schematic diagram of the bill processing flow of the automatic bill identification and processing system. Depend on figure 1 It can be seen that the processing flow of the system is: after the user starts the hardware and software system, the system is in a waiting state. The user places the flat invoice under the camera, and the image acquisition module calculates the trigger signal according to the continuous frame images, and triggers the camera to capture the invoice image. Collect and save to the specified directory of the PC computer. Then, the system automatically processes and recognizes the bill image, and extracts and recognizes the names of buyers and sellers, taxpayer identification number, commodity information (including commodity name, unit of mea...

Abstract

The invention provides a bill automatic identification and processing system based on OCR, which includes an image collection module, a quick image binary module, a text block detection and positioning module, a single column text block accurate positioning module, a multi-column text block accurate positioning and segmentation module, a text identification module, and a bill image retrieval module. The bill automatic identification and processing system based on the OCR can finish the high definition collection and compression storage of invoice bill images, and performs robust and high accurate positioning and identification on literal characters such as information of buying-and-selling sides, goods information, and billing date in each bill. The bill image identification can be conveniently retrieved. The system has the characteristics of high processing and identification precision, low cost, good robustness, and high automation degree, and can be widely used in the computer automatic management of the bills such as the bill authentication and the bill filing and query.

Description

technical field [0001] The invention belongs to the technical field of pattern recognition and artificial intelligence, in particular to an OCR-based bill automatic recognition and processing system. Background technique [0002] OCR-based bill automatic recognition and processing technology refers to the use of computers and other equipment to automatically extract and recognize symbols in paper bills using OCR technology (optical character recognition), and perform corresponding processing. It is one of the key technologies to realize automatic bill computer processing. Despite the increasing development of electronic payments and electronic bills, traditional paper bills are still one of the methods widely used in real work and life, such as various paper invoices and financial bills. There are generally the following methods for automatic computer processing of existing paper bills: (1) Automatic collection and storage of bill images, usually through special equipment f...
