Embodiment Construction

[0072] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0073] The "processing device" referred to in the context is "computer equipment", also known as "computer", which refers to an intelligent electronic device that can perform predetermined processing procedures such as numerical calculations and / or logic calculations by running predetermined programs or instructions, It may include a processor and a memory, and...

Abstract

The object of the present invention is to provide a method and device for acquiring text data of a trademark image. In the present invention, according to the mapping relationship in the trademark database, if the trademark description information corresponding to the trademark feature information corresponding to the image to be processed is included in the image description information corresponding to the image to be processed, then the trademark feature information The corresponding trademark text information is used as the text data of the trademark image corresponding to the image to be processed. Compared with the prior art, the present invention realizes the method of automatically obtaining the text data of the trademark image, can accurately extract the text in the trademark from the product picture, and can quickly obtain a large amount of training data for the deep learning model in a short period of time, Therefore, the recognition efficiency and recognition effect of the model can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a technology for acquiring text data of a trademark image. Background technique [0002] Methods based on deep learning have achieved far better results than traditional methods in many fields, such as face recognition, OCR (Optical Character Recognition, optical character recognition), video classification, etc., and thus have received extensive attention in industry and academia. . For deep learning methods, training data plays a very important role. [0003] In the prior art, training data is usually acquired in the following centralized manner: [0004] (1) Use manual labeling method to obtain training data. That is, using a manual method, on the set of pictures to be marked, mark the target area and the corresponding text information one by one. This method takes a long time, has low standard efficiency, and consumes a lot of manpower. [0005] (2) A semi-autom...
