Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0042] Such as figure 1 As shown, it is a structural block diagram of a system for automatically photographing document images in a specific embodiment of the present invention. The system mainly includes the following five submodules: a photographing environment judgment module 11, an acquisition module 12, a valid document detection module 13, and a shaking detection module 14 and photographing module 15, wherein:

[0043] Shooting environment judging module 11 is used to open camera, obtains the current parameter of camera, judges whether suitable shooting under current environment according to current parameter, if then enters acquisition module, if otherwise prompts inappropriate shooting;

[0044] Wherein, the manner of obtaining the current parameters of the camera includes obtaining through a camera driver, and the parameters include s...

Abstract

The invention relates to a method and system for shooting a document image automatically, and belongs to the field of image shooting. In the prior art, images are acquired mostly in a manual mode, and shot document images cannot easily meet the requirement of follow-up processing. According to the method and system, firstly, a camera is switched on to obtain current parameters, whether a current environment is suitable for shooting is judged, and the camera is used for collecting video streams or the images of a document to be shot if the current environment is suitable for shooting; secondly, whether an effective document exists in the video streams or the images is judged; thirdly, whether a jittering blur exists in the video streams or the images is judged; lastly, the camera is driven to conduct automatic focusing, the shooting of the document to be shot is completed, and the document image is obtained. When the method and system are used for shooting the document image, whether the shooting environment meets requirements, whether the effective document exists in the shooting process, and whether jittering exists in the shooting process can be detected automatically, and the document image can be obtained automatically.

Description

technical field [0001] The invention belongs to the field of image shooting, and in particular relates to a method and system for automatically shooting document images. Background technique [0002] The shooting of document images is mainly used for text recognition. When the quality of the text is poor, the captured image cannot meet the requirements of text recognition. Therefore, text recognition has high requirements on the quality of text images, and a method is needed to be able to Guarantee the quality of the captured text images. [0003] In the existing technology, most of the image acquisition is done manually, and the shooting conditions cannot be automatically judged. The user's subjective judgment of whether the shooting conditions meet the shooting requirements may be different from the actual situation, which easily causes the captured document images to be difficult to meet. Subsequent processing is required and quality cannot be guaranteed. Ordinary autom...
