Embodiment 1

[0064] The invention discloses a method for taking multiple text images and stitching them together, please refer to figure 1 , the method includes the steps of:

[0065] [Step 110] Make the camera far away from the document, just able to capture the entire document, and obtain the full picture of the text.

[0066] The method for capturing the initial text image includes: adjusting the distance between the camera and the document, and when the document to be captured just fills the entire screen of the mobile phone, pressing the capture button to obtain the initial text image.

[0067] [Step 120 ] The user chooses to divide the entire text image into N*M uniform areas, generally divided into 2×2 or 3×3 uniform areas.

[0068] The method for dividing regions includes: dividing the entire initial text image into uniform regions of size N*M. For an example of partitioning see figure 2 , where N takes 2 and M takes 2.

[0069] [Step 130] Calculate the area to be photographed...

Embodiment 2

[0093] This embodiment discloses a method for taking and splicing multiple text images, and the multiple text images taken are used for splicing the text images; the method includes the following steps:

[0094] Step S1, photographing the entire text, and the obtained full image of the entire text is used as a template image;

[0095] Step S2, dividing the entire text image into L regions;

[0096] Step S3, calculate the area to be photographed, and photograph successively; if the kth area was photographed last time, then the k+1th area is to be photographed this time, k≤L-1; the corresponding The region's image is set to be semi-transparent and fill the fill region of the screen;

[0097] Step S4, based on the shooting prompt of the translucent template image, the user shoots a partial image of the text in the corresponding area;

[0098] Step S5, judging whether all the partial images of the document have been photographed, and if it is judged that there are still partial ...

Embodiment 3

[0100] This embodiment discloses a method for taking and splicing multiple text images, and the multiple text images taken are used for splicing the text images; the method includes the following steps:

[0101] Step S1, photographing the entire text, and the obtained full image of the entire text is used as a template image;

[0102] Step S2, dividing the entire text image into L regions;

[0103] Step S3, calculate the area to be photographed, and photograph successively; if the kth area was photographed last time, then the k+1th area is to be photographed this time, k≤L-1; the corresponding The region's image is set to be semi-transparent and fill the fill region of the screen. Wherein, the distance between each edge of the filled area and the edge of the screen can be 0, or a set pixel value.

[0104] Step S4, based on the shooting prompt of the translucent template image, the user shoots a partial image of the text in the corresponding area;

[0105] Step S5, judging w...

Abstract

The invention discloses a method for shooting and matching multiple text images, which comprises the following steps of: shooting the entire text to obtain the total graph of the entire text as a template image; dividing the entire text into L areas; calculating the areas to be shot, and shooting one by one. If the last shooting is in the k area, the k+1 area is shot this time. Images in the corresponding area in the template image are semitransparent, and are filled in the filling area of a screen. Based on the shooting presentation of the semitransparent template image, users shoot the local images of a corresponding area text. Whether all the local images in the text are shot is judged, and if there are also some local images to shoot, shooting is continued. The invention can guaranteethat all the shooting local images can cover the entire text area, and the full picture using the text matched by the local images does not have the circumstance of holes or unfilled corners, therebyonce matching can achieve good effect.

Description

technical field [0001] The invention belongs to the technical field of image processing, and relates to an image splicing method, in particular to a method for shooting and splicing multiple text images. Background technique [0002] With the development of technology, current smart phones generally integrate a digital camera function with auto focus, and people often use the camera on the mobile phone to scan or take text images. For small text such as "business card", the text image scanned by the camera with auto focus function of the mobile phone is very clear, but when the object to be scanned is a large document, such as a magazine cover , test papers or A3-sized documents, etc., since the pixels of the camera on the mobile phone are between 3 million and 5 million, the details of the entire text image captured must be insufficient, so the fonts in the image will be somewhat blurred. [0003] In order to obtain a high-resolution full picture of the document, a common ...
