DETAILED DESCRIPTION

[0021] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0022] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of the present application. The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms of "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0023] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0024] When existing scanning devices scan multiple documents, if there are overlapping areas between the documents, users usually have to wait until the scanning device outputs the scanned file before they can discover the overlapping phenomenon. Users need to open the scanning device and rearrange the documents, which wastes resources and affects the overall scanning efficiency.

[0025] In response to the above problems, an embodiment of the present application provides a scanning method, which can efficiently output normal scanned files by automatically correcting and compensating during the scanning process or prompting the user to make manual corrections before scanning.

[0026] Figure 1 The present invention provides a flow chart of a scanning method. The method can be applied to scanning devices such as Figure 1 As shown, the method may include: Step 101, obtaining the original image of the document to be processed.

[0027] Step 102: When there is an overlapping area in the original image, determine the area of ​​the overlapping area.

[0028] Step 103: output the scanned file of the document to be processed based on the area of ​​the overlapping region.

[0029] After the user places the document to be processed in the scanning area and clicks the scan button, the scanning device can perform a scanning operation on the scanning area to generate an image to be processed. The image to be processed includes the original image of the document to be processed and the background image of the scanning area. The scanning device deletes the background image from the image to be processed to generate the original image of the document to be processed.

[0030] Figure 2is an example of an image to be processed. The position indicated by arrow 201 is the scanning area. During the scanning process, the scanning device will scan the document to be processed and the uncovered scanning area together. Therefore, the image to be processed will contain the original image of the document to be processed and the background image of the scanning area. The original image of the document to be processed can be divided into a content area and a blank area. The content area contains the text or image information of the document to be processed, and the blank area is blank and contains no information. The scanning device can detect the blank area, and after determining the blank area, delete the image outside the blank area, and the remaining image is the original image of the document to be processed. Optionally, the scanning device can set a width threshold (for example, 5mm). When it is detected that the width of the blank area is greater than the width threshold, the blank area can be determined.

[0031] By detecting the blank area, the scanning device can accurately identify the original image of the document to be processed. After applying this method, users do not need to place the document to be processed strictly according to the rules. Even if the document to be processed is tilted or upside down, the scanning device can still normally obtain the original image of the document to be processed, which improves the user experience.

[0032] In a scenario where multiple documents to be processed are placed in the scanning area for scanning at the same time, the scanning device needs to detect whether there is an overlapping area in the original image after obtaining the original image of the documents to be processed. If it is confirmed that there is an overlapping area in the original image, the scanning device needs to further determine the area of ​​the overlapping area, and then output the scanned file of the document to be processed based on the area of ​​the overlapping area.

[0033] In an optional embodiment, when the area of ​​the overlapping region is small, it can be considered that the current overlapping phenomenon has little impact on the content information in the document to be processed, and the scanning device can automatically correct and compensate the original image and output the corrected and compensated scanned file. When the area of ​​the overlapping region is large, it can be considered that the current overlapping phenomenon has a significant impact on the content information in the document to be processed, and the scanning device will output a prompt message to prompt the user to manually adjust the placement of the document to be processed to eliminate the overlapping region.

[0034] Specifically, the scanning device can pre-set a reasonable area threshold. When it is detected that the area of ​​the overlapping area is less than the preset area threshold, the original image is corrected and compensated to generate a corresponding corrected image. Then, the scanning device can output a scanned file of the document to be processed based on the corrected image. When it is detected that the area of ​​the overlapping area is not less than the preset area threshold, the scanning device will output a prompt message through the control panel. After seeing the prompt message, the user can turn on the scanning device, adjust the placement of the document to be processed, and rescan it.

[0035] By applying the above method, when overlap occurs between different documents to be processed, the scanning device can achieve normal output of the scanned files through correction compensation, or notify the user to manually eliminate the overlapping area before outputting the scanned files, thereby improving scanning efficiency.

[0036] In an optional embodiment, the scanning device can determine whether there is an overlapping area in the original image of the document to be processed by the angle. Figure 3 When two documents to be processed partially overlap, an angle will appear on the edge of the documents to be processed. When the scanning device detects that an angle appears in the original image, it can be confirmed that there is an overlapping area in the original image. In another embodiment, the overlapping area can also be determined by identifying whether there is an obstruction. Specifically, the scanned image to be processed is identified, and when it is identified that there are images of other documents to be processed on the image of a document to be processed, it is determined that the original image of the document to be processed has the overlapping area. In actual processing, the method of confirming the overlapping area by the angle is simple and easy to implement, does not require high chip configuration, and can save chip resources.

[0037] In an optional embodiment, when it is detected that there is an overlapping area in the original image, the scanning device can specifically determine the area of ​​the overlapping area in the following manner: (1) The area of ​​the overlapping area is determined based on the length of the right-angle side of the overlapping area. (2) The area of ​​the overlapping area is determined based on the size of the first angle and the second angle between the original images of the document to be processed, and the vertex distance between the first angle and the second angle. (3) The area of ​​the overlapping area is determined based on the area ratio of the original image to the standard image.

[0038] The following examples illustrate: (1) Refer to Figure 4A , an overlapping area appears between the two documents to be processed, and the dotted line is the obstructed right-angled side, including the long right-angled side a and the short right-angled side b. The scanning device can extend the original right-angled side in the direction to complete the obstructed long right-angled side a and the short right-angled side b, and determine the length of the long right-angled side a and the short right-angled side b. Through the triangle area formula and the length of the long right-angled side a and the short right-angled side b, the scanning device can determine the area of ​​the obstructed triangle, that is, the area of ​​the overlapping area. Take A4 paper as an example. The size of A4 paper is 210mm 297mm. If the long right-angle side a is 10mm and the short right-angle side b is 8mm, the area of ​​the overlapping area calculated by the triangle area calculation formula is 8 10 1 / 2=40mm², the ratio of the overlapping area to the total area is 40 / (210 297)≈0.06%. The scanning device can determine that the current overlapping area is small, and can output the scanned file after correction and compensation. If the long right-angle side a is 120mm and the short right-angle side b is 100mm, then the area of ​​the overlapping area is 120 100 1 / 2=6000mm², the area of ​​the overlapping area accounts for about 9.6% of the total area. The scanning device can determine that the area of ​​the current overlapping area is too large, and it is necessary to remind the user to pay attention to the placement position on the control panel.

[0039] (2) Reference Figure 4B , the positions indicated by arrows 401 and 402 are two vertices of the overlapping area, angle m and angle n are the first angle and the second angle, respectively, and the distance between the two vertices is the hypotenuse c of the triangle of the overlapping area. Under the condition that the hypotenuse c, angle m and angle n are known, the scanning device can calculate the area of ​​the overlapping area. For example, the lengths of the other two right-angled sides can be obtained by trigonometric formulas, and then the area of ​​the triangle can be calculated.

[0040] (3) Reference Figure 4C , three documents (Document A, Document B, and Document C) are scanned at the same time, and the original image of Document C can be regarded as the standard image. The scanning device compares the original images of Document A and Document B with the standard image to determine the area of ​​the overlapping area. For example, when the total area of ​​Document A and Document B is 1.96 times the standard image area, it can be determined that the area of ​​the overlapping area is 0.04 times the standard image area, and the area of ​​the overlapping area is small. Automatic correction compensation can be used to output the scanned file. When the total area of ​​Document A and Document B is 1.90 times the standard image area, it can be determined that the area of ​​the overlapping area is 0.10 times the standard image area, and the area of ​​the overlapping area is large. The scanning device needs to notify the user to manually adjust the documents to be processed.

[0041] In addition, the scanning device can also calculate the area of ​​the overlapping area through image recognition algorithms.

[0042] In the embodiment of the present application, the overlapping phenomenon may be caused by scanning multiple pages, or it may be caused by folding of the document to be processed itself. Through the above-mentioned overlapping area recognition and calculation method, the overlapping phenomenon in various scenarios can be processed and the complete scanned file can be smoothly output.

[0043] In the process of determining the area of ​​the overlapping region, the control panel can display a related interface to interact with the user. Figure 4D, the preset format is the area of ​​the standard image. Users can select the "Preset Format" option to modify the specific value of the standard image area. When the user selects "Automatically Identify Format", the scanning device can automatically calculate the area ratio of the original image and the standard image, and then determine the area of ​​the overlapping area. When the area of ​​the overlapping area is large, the control panel can display a prompt message. Figure 4E , the control panel can display the message "The overlapping area is too large, please pay attention to the placement" to the user. After the user clicks "Confirm", the scanning device stops working and the user manually adjusts the placement of the document. After the user clicks "Ignore", the scanning device continues to execute the subsequent process and outputs the scanned file.

[0044] In the embodiment of the present application, the scanning device can select any one of the above methods to calculate the area of ​​the overlapping area, or can calculate the area of ​​the overlapping area by setting weights and combining multiple methods, which is not limited here. Through the above methods, the scanning device can accurately calculate the area of ​​the overlapping area, and then perform the corresponding multi-page scanning operation to improve the scanning effect. The above area calculation method is only an exemplary description, and other reasonable methods can also be used to determine the area of ​​the overlapping area.

[0045] In an optional embodiment, in a scenario where multiple documents to be processed overlap, the scanning device will correct and compensate for the obscured original image to generate a corresponding corrected image. Specifically, the scanning area will first compensate for the right angles of the obscured original image, and then supplement it according to the color of the surrounding area after compensating it to a normal paper format. For example, for ordinary document portraits, the periphery of the overlapping area is white, and the color compensation within the right angle is also white. However, for brochures and other documents whose surrounding colors are not white, the color of the overlapping area can be selected, and the user can choose to fill it according to the surrounding color. Refer to Figure 5A Document A is a promotional page consisting of gray and white colors. When scanning, the gray triangular area of ​​Document A is blocked by Document B. In response to this situation, the scanning device first performs right-angle compensation on Document A to determine the complete original image of Document A. Afterwards, the scanning device performs color compensation on the blocked area of ​​Document A, and the color can refer to the color of the area surrounding the blocked area. When performing color compensation on Document A, the scanning device can refer to the color of the area indicated by arrow 501 and fill the blocked area with gray. It can be understood that for documents with simpler colors, the color of the blocked area is usually consistent with its surrounding colors. Color compensation of the blocked area based on the colors around the blocked area can reasonably restore the original image of the document.

[0046] When performing color compensation, the user can also manually determine the color of the blocked area. Specifically, the scanning device displays an image adjustment interface, and performs color compensation on the compensation area on the original image according to the color selected from the image adjustment interface to obtain a corrected image. The compensation area matches the overlapping area, and is the area obtained after correcting and compensating the original image based on the overlapping area. Optionally, the image adjustment interface includes a color picking section, which contains a variety of optional colors, and the user can select a color for compensation in the color picking section. The colors contained in the color picking section are determined by the colors of the adjacent areas of the compensation area, refer to Figure 5A When the color of the adjacent area of ​​the compensation area is gray, the color extraction part mainly includes gray-based colors.

[0047] In a specific scenario, the scanning device obtains the color of an area adjacent to the compensation area, and then generates an image adjustment interface including a color picking portion based on the color of the adjacent area. Figure 5B It can be seen as a schematic diagram of the image adjustment interface. The area indicated by arrow 502 is the color selection part. The user can move the rectangular selection box in the area to select the color for compensation. The control panel displays a preview image of the color compensation in the preview area. After the user selects a color and clicks "Confirm", the scanning device can perform color compensation on the blocked area.

[0048] In an optional embodiment, when scanning multiple documents to be processed at the same time, in response to a user's first filling request, the scanning device may determine the original image of one of the documents to be processed as a first filling image, and fill the first filling image into the filling area of ​​another document to be processed to obtain a first merged image. Afterwards, the scanning device may output a scanned file of the first merged image.

[0049] Reference Fig. 6A Document A is the original image of a personal information application form. The white area is blank, and there is no user ID photo. Other user information exists in the light gray area. Document B is the original image of the user's ID photo, and its color is dark gray. The user can place Document A and Document B in the scanning area of ​​the scanning device at the same time for multi-page scanning. The scanning device displays the original images of Document A and Document B on the control panel. The user can drag the original image of Document B to the filling area of ​​the original image of Document A on the control panel. The scanning device detects the user's filling request and fills the original image of Text B into the filling area of ​​the original image of Document A to obtain the corresponding merged image. Alternatively, the user can also directly select the fill button on the control panel, and the scanning device directly identifies the structure of each original image, automatically confirms the fill image and completes the filling. There is no limit on the number of fill images, refer to Figure 6B In response to the user's dragging operation, the scanning device can fill multiple filling images into corresponding filling areas respectively.

[0050] Reference Figure 6C , after the user selects the fill scan mode, the scanning device displays the "single fill" and "multiple fill" options through the control panel. When there is only one fill image in the scan area, the user can click the "single fill" option, and the scanning device directly performs image recognition to determine the first fill image and complete the filling. When there are multiple first fill images in the scan area, the user can click the "multiple fill" option, and the scanning device displays each original image through the control panel, and the user can manually drag and drop to fill the corresponding image. Optionally, when filling a single image, the user can also complete the filling by dragging.

[0051] In an optional embodiment, the scanning device may also store certain images as fill images in advance. In response to the user's second fill request, the scanning device obtains the pre-stored second fill image and fills the second fill image into the fill area corresponding to the original image to obtain a second merged image. Afterwards, the scanning device may output a scan file of the second merged image. Fig.6D , users can manually select a fill image in the "Fill Image Selection" interface. The pre-stored second fill images include: custom images and official preset images. Official preset images may include images stored in the local database when the scanning device leaves the factory, or official preset images may also include images downloaded from the Internet by the scanning device. Custom images include images uploaded by users themselves. For example, after the user connects the mobile phone to the scanning device, he can send pictures from the album in his mobile phone to the scanning device. The "Custom Image" interface can display existing fill images. Fig.6D For example, the current scanning device has stored images such as "XX one-inch red-backed photo", "XX ID card front side" and "XX ID card back side". Users can use the "New" option to store other images as fill images, or use the "Delete" option to delete existing fill images.

[0052] During the filling process, the scanning device can adjust the specifications of the filling image so that the adjusted filling image matches the filling area. Specifically, the specification adjustment may include: size adjustment, quantity adjustment, and direction adjustment. For example, when a two-inch ID photo is missing in the user's personal information form and the filling image is the user's one-inch ID photo, the scanning device can increase the size of the one-inch ID photo to match the filling area in the personal information form. When there are multiple filling areas and only one filling image, the scanning device can adjust the quantity of the filling image and copy a single filling image multiple times to meet each filling area. When the placement direction of the filling image does not match the filling area, the scanning device can adjust the direction of the filling image to achieve matching between the two.

[0053] In the embodiment of the present application, through the above-mentioned filling operation, the scanning device can realize flexible combination between images and improve the work efficiency of the user. For example, for the above-mentioned personal information table, the user does not need to paste the ID photo into the personal information table to obtain a scanned file combining the two. For another example, when there are multiple personal information tables and only one ID photo, the user does not need to take the ID photo again or paste the ID photo repeatedly into different personal information tables. The completed scanned file can be obtained by image filling and specification adjustment. This method can save the user's time and improve the user experience.
