Description

Technical Field

[0001] This article relates to the field of artificial intelligence technology, and in particular to an intelligent stamping method, device, system, equipment and storage medium. Background Technology

[0002] Countertop stamping machines are used to stamp stacks of paper. Existing countertop stamping machines, due to the fixed positions of the paper tray and stamping lever, can only stamp documents placed in the tray at fixed locations. When a large amount of content is already printed at the fixed stamping location, the existing countertop stamping machine cannot intelligently identify suitable blank areas in the document like a human can. Therefore, after stamping, the stamp on the paper overlaps with the original content, reducing the user's document viewing experience.

[0003] There is an urgent need for an intelligent stamping method to solve the problem that existing counter-based stamping machines cannot intelligently identify suitable blank areas in documents to be stamped. This results in overlap between the stamp and the original content when there is already a lot of content at the fixed stamping position on the document, which reduces the user's document viewing experience. Summary of the Invention

[0004] To address the problems in the prior art, embodiments of this specification provide an intelligent stamping method, apparatus, system, device, and storage medium, which realizes the identification of blank areas of documents to be stamped and stamps the blank areas.

[0005] To solve any of the above-mentioned technical problems, the specific technical solution presented in this paper is as follows:

[0006] On the one hand, the embodiments of this specification provide an intelligent stamping method, including,

[0008] The light intensity value of each area of ​​the document to be stamped is obtained by scanning each area located below the light receiving element using all light receiving elements within the optical detection range.

[0009] If the light intensity value meets the light intensity reference value requirement of the document to be stamped, the area shall be used as the stamping area.

[0010] The seal is affixed to the area to be stamped.

[0011] Furthermore, multiple light-receiving elements are arranged at uniform intervals within the optical detection range.

[0014] The area containing the number of light-receiving elements evenly spaced on the detection component is defined as the optical detection range.

[0015] Furthermore, the detection area composed of all the light-receiving elements on the light quantity detection component is greater than or equal to the area of ​​the document to be stamped;

[0027] If so, the currently scanned area will be used as the stamping area, scanning of other areas will be stopped, and the stamp will be placed in the stamping area.

[0028] If not, continue scanning other areas of the document to be stamped;

[0045] On the other hand, embodiments of this specification also provide an intelligent stamping device, the device comprising:

[0046] An optical detection range determination unit is used to determine the optical detection range corresponding to the size of the seal, wherein the optical detection range includes multiple photoelectric sensors;

[0056] On the other hand, embodiments of this specification also provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the above-described method.

[0057] Finally, this specification also provides a computer program product, which includes a computer program that, when executed by a processor, implements the above-described method.

[0058] Using the embodiments of this specification, the document to be stamped may contain printed content. The intelligent stamping method of this specification automatically identifies the appropriate stamping area on the document. Specifically, firstly, the optical detection range is determined based on the size of the stamp. Then, all light-receiving elements within the optical detection range are used to scan each area of ​​the document to be stamped below the light-receiving elements to obtain the light intensity value of each area. White paper reflects all the light shining on it, while black text absorbs all the light and has no reflective properties. If there is more printed content in the area corresponding to the optical detection range, the light intensity value of that area is smaller, and vice versa. Therefore, it is determined whether the light intensity value meets the requirements of the light intensity reference value. If it does, it means that the area is suitable for stamping, and thus the area is designated as the stamping area, and the stamp is placed within the stamping area. Through the method of the embodiments of this specification, the appropriate stamping area on the document to be stamped is identified using optical detection. Compared with the traditional method of stamping in a fixed position, this method can reduce or avoid overlap between the stamp and the original content on the paper, improving the user's document viewing experience.

[0096] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings.

[0098] It should be noted that the acquisition, storage, use, and processing of data in the technical solution of this application all comply with the relevant provisions of national laws and regulations.

[0099] Figure 4 The diagram shown is a comparison of the stamping position in the embodiments of this specification with the stamping position in the prior art. In the prior art, the stamp is affixed to a fixed position on the document to be stamped, but the fixed position may already have content printed on it. Therefore, in the embodiments of this specification, each area of ​​the document to be stamped is optically scanned to obtain blank stamping areas for stamping.

[0100] Specifically, this specification provides an intelligent stamping method that identifies blank areas of a document to be stamped and stamps the blank areas. Figure 1 The diagram shown is a flowchart illustrating an intelligent stamping method according to an embodiment of this specification. The diagram depicts the process of identifying the stamping area of ​​a document using optical detection principles. The order of steps listed in the embodiment is merely one possible execution order among many and does not represent the only possible order. In actual system or device products, the method can be executed sequentially or in parallel, as shown in the embodiment or the accompanying drawings. Specifically, as... Figure 1 As shown, the method may include:

[0101] Step 101: Determine the optical detection range corresponding to the size of the seal, wherein the optical detection range includes multiple light-receiving elements;

[0102] Step 102: Use all light-receiving elements within the optical detection range to scan each area of ​​the document to be stamped located below the light-receiving elements to obtain the light intensity value of each area;

[0103] Step 103: If the light intensity value meets the light intensity reference value requirement of the document to be stamped, the area is designated as the stamping area.

[0104] Step 104: Place the stamp on the stamping area.

[0105] Using the embodiments of this specification, the document to be stamped may contain printed content. The intelligent stamping method of this specification automatically identifies the appropriate stamping area on the document. Specifically, firstly, the optical detection range is determined based on the size of the stamp. Then, all light-receiving elements within the optical detection range are used to scan each area of ​​the document to be stamped below the light-receiving elements to obtain the light intensity value of each area. White paper reflects all the light shining on it, while black text absorbs all the light and has no reflective properties. If there is more printed content in the area corresponding to the optical detection range, the light intensity value of that area is smaller, and vice versa. Therefore, it is determined whether the light intensity value meets the requirements of the light intensity reference value. If it does, it means that the area is suitable for stamping, and thus the area is designated as the stamping area, and the stamp is placed within the stamping area. Through the method of the embodiments of this specification, the appropriate stamping area on the document to be stamped is identified using optical detection. Compared with the traditional method of stamping in a fixed position, this method can reduce or avoid overlap between the stamp and the original content on the paper, improving the user's document viewing experience.

[0106] like Figures 2-3 The diagram shown illustrates the principle of optical detection in this embodiment. The emitter can be an LED light source or other light-emitting element. The emitted light shines onto the document to be stamped and is reflected by the document. The light-receiving element receives the reflected light and converts it into a digital signal. This digital signal is then processed and output. If the document already has printed content, the emitted light will be absorbed by the existing content, resulting in a reflected light intensity lower than the emitted light intensity. The denser or darker the printed content in the detection area, the more light is absorbed and the less intense the reflected light. Therefore, the density or color depth of the printed content on the document is determined based on the intensity of the reflected light, allowing for stamping in areas with denser or darker printed content.

[0107] In the embodiments of this specification, the document to be stamped can be divided into multiple continuous areas in advance. The area of ​​each area should be greater than or equal to the optical detection range. Each area is scanned using all light-receiving elements within the optical detection range to obtain the light intensity value of each area. Then, it is determined whether each light intensity value meets the requirements of the light intensity reference value. If it does, the area is used as the stamping area.

[0108] In the embodiments of this specification, the light intensity reference value can be set according to experience or stamping requirements. The larger the light intensity reference value, the less content is printed in the determined stamping area, and the better the user's reading experience after stamping.

[0109] According to one embodiment of the present invention, in order to facilitate the calculation of the light intensity value of each region, the embodiments of this specification arrange multiple light-receiving elements at uniform intervals within the optical detection range, which makes it easier to calculate the light intensity value of the region scanned by the optical detection range.

[0110] Specifically, calculating the light intensity value corresponding to the optical detection range further includes:

[0111] The light intensity value is calculated based on the values ​​of each light-receiving element.

[0112] In the embodiments of this specification, the light-receiving element can convert the received light signal into a digital signal, and calculate the light intensity value based on the value of the digital signal output by each light-receiving element. Specifically, the average value of each light-receiving element can be calculated, and the average value can be used as the light intensity value.

[0113] According to one embodiment of the present invention, such as Figure 5 As shown, determining the optical detection range corresponding to the size of the seal further includes:

[0114] Step 501: On a light intensity detection component comprising multiple light-receiving elements arranged at uniform intervals, the number of light-receiving elements corresponding to the size of the stamp is determined according to the size of the stamp and the interval of the light-receiving elements, and the light intensity detection component is located above the stamping surface of the document to be stamped;

[0115] Step 502: The area where the number of light-receiving elements are evenly spaced on the detection component is located is defined as the optical detection range.

[0116] In the embodiments of this specification, the light-receiving elements to be scanned can be delineated according to the optical detection range, further improving the accuracy of light quantity calculation. Specifically, as shown in the example... Figure 6 As shown, the light-receiving elements are arranged at uniform intervals of 1cm x 1cm on the light intensity detection component. The light intensity detection component is located above the document to be stamped, emitting light downwards to illuminate the document. If a 4cm x 3cm stamp is required, a total of 12 light-receiving elements (4 x 3) are needed, and the area containing these 12 light-receiving elements is defined as the optical detection range.

[0117] In the embodiments of this specification, although the document to be stamped can be pre-divided into multiple continuous regions and the light-receiving element can be controlled to scan each region, the detection granularity of this region division method is relatively coarse. It only fully covers the document to be stamped, and the content already printed at the junction of two regions may be less, making it more suitable for stamping. To address the above situation, according to an embodiment of the present invention, the detection area composed of all the light-receiving elements on the light intensity detection component is set to be greater than or equal to the area of ​​the document to be stamped, that is, the detection area of ​​the optical detection component can cover the entire document to be stamped. The present invention does not require moving the light-receiving element, but controls the operation of different light-receiving elements to achieve the purpose of moving the detection area. Specifically, scanning each region of the document to be stamped using all the light-receiving elements within the optical detection range further includes:

[0118] The optical detection range is moved in the horizontal or vertical direction of the document to be stamped, with the interval between two adjacent light-receiving elements as the step size, to scan each area of ​​the document to be stamped.

[0119] For example, such as Figure 7 As shown, A represents the optical detection range composed of the currently working light-receiving elements. The optical detection range is moved with the interval between two adjacent light-receiving elements as the step size to obtain a new optical detection range B. The area corresponding to the optical detection range B is scanned using multiple light-receiving elements within the optical detection range B.

[0120] This method can be understood as allowing overlapping areas to be included in each detection area, thus enabling more granular detection of the document to be stamped and identifying more suitable stamping areas.

[0121] According to one embodiment of the present invention, such as Figure 8 As shown, the steps for calculating the light intensity reference value include:

[0122] Step 801: Use all light-receiving elements within the optical detection range to scan the area of ​​the document to be stamped that does not contain any content located below the light-receiving elements, and obtain the light intensity value of that area;

[0123] Step 802: Use the light intensity value of this area as the light intensity reference value.

[0124] In the embodiments of this specification, the ideal stamping area for the document to be stamped should be an area without printed content. Therefore, the light intensity value corresponding to the area without printed content can be used as a light intensity reference value. If the light intensity value of other areas is closer to the light intensity reference value, then that area is more likely to be without printed content. This ensures that the stamp is printed on an area without printed content as much as possible.

[0125] According to an embodiment of the present invention, in order to improve the efficiency of determining the stamping area, in the process of scanning each area of ​​the document to be stamped using all light-receiving elements within the optical detection range to obtain the light intensity value corresponding to each area, the method further includes:

[0126] Determine whether the light intensity value of the currently scanned area is greater than or equal to the light intensity reference value;

[0127] If so, the currently scanned area will be used as the stamping area, scanning of other areas will be stopped, and the stamp will be placed in the stamping area.

[0128] If not, continue scanning other areas of the document to be stamped;

[0129] If the light intensity value of each area of ​​the document to be stamped is less than the light intensity reference value, then the area corresponding to the maximum light intensity value shall be the stamping area.

[0130] In the embodiments of this specification, during the scanning of the document to be stamped using all light-receiving elements within the optical detection range, after scanning one area, it is determined whether the light intensity value of that area is greater than or equal to the light intensity reference value. If so, that area is designated as the stamping area, scanning of other areas is stopped, and the stamp is placed on that stamping area. If the light intensity value of that area is less than the light intensity reference value, scanning of other areas of the document to be stamped continues. If, after scanning all areas of the document to be stamped, the light intensity value of each area is less than the light intensity reference value, it indicates that each area has already been imprinted with content. Therefore, the area with the highest light intensity value is designated as the stamping area, allowing the stamp to be placed on the area with the least content.

[0131] Furthermore, to further enhance the user experience, a preferred stamping area can be set on the document to be stamped, for example, setting the lower right corner of the document as the preferred stamping area. Specifically, such as... Figure 9 As shown, the method further includes:

[0132] Step 901: First, scan the predetermined preferred stamping area of ​​the document to be stamped using all light-receiving elements within the optical detection range to obtain the light intensity value corresponding to the predetermined preferred stamping area;

[0133] Step 902: If the light intensity value corresponding to the predetermined preferred stamping area is greater than or equal to the light intensity reference value, then the predetermined preferred stamping area is taken as the stamping area, scanning of other areas is stopped, and the stamp is affixed to the stamping area.

[0134] This can be understood as follows: First, the preferred stamping area is scanned. If the light intensity value of the preferred stamping area meets the light intensity reference value requirement, then a stamp is placed on the preferred stamping area. Otherwise, other areas are scanned until the light intensity value meets the requirement. If the light intensity value of all areas does not meet the requirement, the area corresponding to the highest light intensity value can be used as the stamping area. Alternatively, it can be determined whether the light intensity value of the preferred stamping area exceeds the average light intensity value of all areas. If so, it indicates that although content is already printed on the preferred stamping area, the density of the content is not the highest among all areas, so further stamping can continue on the preferred stamping area.

[0135] Currently, the need for stamping documents extends beyond single documents; it may also involve stamping multiple documents together to indicate they are a set, preventing unauthorized swapping. For this scenario, embodiments of this specification can stack multiple documents sequentially, treating them as a single unit, identifying the appropriate stamping area, and then stamping. Specifically, according to one embodiment of the present invention, such as... Figure 10 As shown:

[0136] The method further includes:

[0137] Step 1001: Calculate the ratio of the horizontal dimension of the seal to the number of documents to be stamped, and use the ratio as the stamping width of each document to be stamped;

[0138] Step 1002: Stack the documents to be stamped horizontally according to the stamp width. For two adjacent documents to be stamped, the distance between the side of the upper document and the side of the lower document in the same direction is the stamp width.

[0139] Step 1003: Take the side of the bottommost document to be stamped in the stacked arrangement as the first boundary; take one side of the optical detection range adjacent to the first boundary and make sure the optical detection range can cover all documents to be stamped; use all the light-receiving elements in the optical detection range to scan along the longitudinal direction of the documents to be stamped to obtain the light intensity value of each region.

[0140] Step 1004: If the light intensity value meets the light intensity reference value requirement of the document to be stamped, the area is designated as the stamping area.

[0141] Step 1005: Place the stamp on the stamping area.

[0142] In the embodiments of this specification, according to the conventional side-stamping requirements, the stamp needs to cover multiple documents, each document having a portion of the stamp, and the order is fixed. Therefore, multiple documents need to be stacked sequentially. First, the ratio of the horizontal dimension of the stamp to the number of documents to be stamped is calculated; this ratio represents the stamp width on each document. Then, the documents to be stamped are stacked horizontally according to the stamp width. For two adjacent documents, the distance between the side of the upper document and the side of the lower document in the same direction is the stamp width. For example, the first document is at the bottom, and then the second document is stacked on top of the first document. The distance between the side of the second document and the side of the first document in the same direction is the stamp width, and multiple documents are stacked together sequentially. After stacking, the distance between the side of the bottom layer document and the side of the top layer document in the same direction is equal to the difference between the horizontal dimension of the stamp and the stamp width of a document. In this way, as long as one side of the stamp is placed close to the side of the bottom layer document, it is possible to have part of the stamp on each document.

[0143] After stacking multiple documents to be stamped, the side of the bottom document in the stack is designated as the first boundary. One side of the optical detection range is adjacent to the first boundary, and the optical detection range can cover all documents to be stamped. All light-receiving elements within the optical detection range are used to scan along the longitudinal direction of the documents to be stamped to obtain the light intensity value of each region. If the light intensity value meets the light intensity reference value requirement of the documents to be stamped, the region is designated as the stamping region.

[0144] Based on the same inventive concept, embodiments of this specification also provide an intelligent stamping device, such as... Figure 11 As shown, it includes:

[0145] An optical detection range determination unit 1101 is used to determine the optical detection range corresponding to the size of the seal, wherein the optical detection range includes multiple photoelectric sensors.

[0146] The scanning unit 1102 is used to scan each area of ​​the document to be stamped located below the light-receiving elements using all light-receiving elements within the optical detection range, and to obtain the light intensity value of each area.

[0147] The stamping area determination unit 1103 is used to determine the area as the stamping area when the light intensity value meets the light intensity reference value requirement of the document to be stamped.

[0148] The stamping unit 1104 is used to affix the stamp to the stamping area.

[0149] Since the principle of the above-mentioned device in solving the problem is similar to that of the above-mentioned method, the implementation of the above-mentioned device can refer to the implementation of the above-mentioned method, and the repeated parts will not be described again.

[0150] Based on the same inventive concept, embodiments of this specification also provide an intelligent stamping system, such as... Figure 12 The diagram shown is a structural schematic of the intelligent stamp system in an embodiment of this specification, which may include a stamp 1201, a stamp rod 1202, multiple light-receiving elements 1203, and the intelligent stamping device 1204 described above.

[0151] The light-receiving element 1203 is located above the document to be stamped and is used to scan each area of ​​the document to be stamped;

[0152] The intelligent stamping device 1204 is used to calculate the stamping area of ​​the document to be stamped based on the values ​​scanned by the light-receiving element 1203.

[0153] The stamp rod 1202 is located above the document to be stamped, and one end of the stamp rod 1202 is connected to the stamp 1201;

[0154] The intelligent stamping device 1204 is further used to control the movement of the stamp rod 1202 until the projection area of ​​the stamp 1201 on the document to be stamped is located within the stamping area, and to control the stamp 1201 to stamp the document to be stamped.

[0155] Furthermore, according to one embodiment of the present invention, such as Figure 13 As shown: stamping the seal within the stamping area further includes:

[0156] Step 1301: Control the movement of the stamp rod located above the document to be stamped until the projection area of ​​the stamp connected to one end of the stamp rod on the document to be stamped is located within the stamping area;

[0157] Step 1302: Control the stamp to affix the seal to the document to be stamped.

[0158] Specifically, the steps for controlling the movement of the stamp rod include:

[0159] On a plane parallel to the plane of the document to be stamped, rotate the stamp rod with the end of the stamp rod furthest from the stamp as the origin, and adjust the extension and retraction length of the stamp rod until the projection area of ​​the stamp on the document to be stamped is located in the stamping area.

[0160] In the embodiments described in this specification, the following continues... Figure 12As shown, the stamp rod 1202 is positioned above the document to be stamped.
