Embodiment Construction

[0021] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0022] With the popularity of electronic business cards and electronic devices, it has become a common phenomenon to use electronic devices to record business card information. However, it takes a lot of time and energy to enter paper business cards into electronic business cards, so it is of great significance to automate this process.

[0023] At present, there are mainly three business card recognition methods as follows:

[0024] The first one is to rely on a limited recognition device to obtain the image of the p...

Abstract

The invention provides a business card identification method and device, and the method comprises the steps: obtaining a to-be-identified business card image; inputting the business card image into acharacter detection model to obtain each text line area, wherein the character detection model learns and obtain a corresponding relation between image features and each text line area; and inputtingeach text line area into the character recognition model to obtain business card information corresponding to each text line area. According to the method, the text line areas in the business card image can be identified through the text detection model based on deep learning, the robustness is high, the influence of low-quality and noise data on text extraction can be reduced, and therefore the universality and the application space of the method are improved. Moreover, the text line areas are subjected to end-to-end recognition based on the deep learning character recognition model, single word segmentation is not needed, higher accuracy is achieved, higher recognition capability is achieved for various complex changes, and the universality and the recognition effect of the method are improved.

Description

technical field [0001] The invention relates to the technical field of machine learning, in particular to a business card recognition method and device. Background technique [0002] With the popularization and development of personal computers (PC for short) and mobile terminals, it has gradually become the mainstream to store and retrieve paper business cards using electronic information. However, it takes a lot of manpower and material resources to convert paper business cards into electronic business cards. Therefore, it is very important to complete this process automatically. [0003] After long-term exploration and research by different scholars, there have been many application examples of business card recognition methods. However, the traditional business card recognition method is limited by the optical character recognition (Optical Character Recognition, OCR) technology used, and the business card image quality is relatively low. Low, for example, in the case o...
