[0032] The embodiment of the present invention provides a personalized card display and production method, see Figure 1 , the method comprising:

[0033] 101. Receive a personality picture and a card template, perform color space conversion on the personality picture to obtain a first personality picture, synthesize the first personality picture and the card template in a canvas group to obtain a preview picture, and adjust parameters of the personality picture according to the preview picture to obtain a second personality picture;

[0034] 102. Determine that the layout of the second personalized picture and the card template is horizontal, then perform color space conversion on the second personalized picture and the card template to obtain a third personalized picture and the first card template, and synthesize the third personalized picture and the first card template to obtain a personalized card.

[0035] Based on the content of the above method embodiment, as an optional embodiment, the personalized card display and production method provided in the embodiment of the present invention, the canvas group is divided into four layers, including: a template layer, located at the top layer of the canvas group, used to display the template layer image; an area selection layer, adjacent to the template layer, used to draw a highlight selection box for the card surface partition; a foreground layer, adjacent to the area selection layer, used to display the foreground image of the card surface; a background layer, adjacent to the foreground layer, used to place a personalized image.

[0036] For details, please refer to Figure 2 According to the definition in the international standard ISO / IEC 7810, the size of the ID-1 standard card face is 85.60mm×53.98mm×0.76mm. According to the printer printing test results, select the resolution of the card face image. The drawing area size is calculated by the formula: actual size (inches) = pixels / resolution. The following uses HTML5 to introduce the method of this example, but it is not limited to HTML5 implementation. HTML has its own particularity because of the existence of CSS (Cascading Style Sheets). In the design of the canvas, the aspect ratio of the canvas must be consistent with the aspect ratio of the style to ensure the normal display of the image. Defined in HTML Container, create a canvas group in the container, 4 canvases. The canvas group contains stacked transparent canvases of the same size and absolute position. Its size is the size of the drawing area calculated above mapped to the size of the display screen, that is, the aspect ratio of the card is mapped to the area that can be displayed on the screen. Four layers: In order to make the user usability smooth, the canvas group is composed of template layer, area selection layer, foreground layer, and background layer from top to bottom.

[0037] The template layer S101 is located at the top of the canvas group. Its content is an optional fixed picture used to show the purpose of the card and the basic elements of the card surface, including at least one of the chip icon, UnionPay icon, bank icon, card number, card image, and co-branded card image.

[0038] The area selection layer S102 is located in the next layer of the template layer, and is used to draw highlight selection boxes for card surface partitions. For example, a poster-type card surface is divided into picture and text areas. Selecting the picture area will draw a highlight selection box on this layer to prompt the user to upload the picture; selecting the text area will prompt the user to edit the text; a puzzle-type card surface divides the card surface into multiple pictures. When a certain area is selected, a highlight selection box will be drawn on this layer to prompt the user to edit the picture in that area.

[0039] The foreground layer S103 is located below the area selection layer and is used to display the foreground image of the card surface, such as a poster-type image and a connecting image between text areas. This layer is an optional layer and will only appear when the card surface is selected to have partitions.

[0040] The background layer S104 is located at the bottom layer of the canvas group and is used for user-defined pictures of the card, such as cartoon pictures, character pictures, and animal pictures.

[0041] The division of regions can be found in Figure 3 , region refers to dividing the canvas into multiple closed polygons through one or more dividing lines, and each polygon is a region. Including but not limited to the regional foreground image, foreground text set, and the set of polygon vertices in the region. The dividing line S203 divides the canvas into two closed polygons S201 and S202. S201 and S202 are the two regions of this layout. In HTML5, a closed path is cut out in the canvas through the clip method to obtain a region. On the background layer canvas, the points in the region are connected into multiple closed paths in a clockwise direction, and the region is cut out. The user's background image is drawn in the above-mentioned region, and the regional foreground image and foreground text set are drawn on the foreground layer canvas. The text set includes but is not limited to font, text content, font size, text color, and font thickness.

[0042] Based on the content of the above method embodiment, as an optional embodiment, the personalized card display and production method provided in the embodiment of the present invention, the card template includes: the template layer map and the template PDF map, both of which are used to provide basic patterns of personalized cards.

[0043] Specifically, in order to realize the operability of the layer, the mouse and touch events are registered in the canvas of the template layer S101, and the user can operate the picture of the background layer through the mouse or gestures. The template layer S101 parameter configuration, the system draws the card template in the template layer S101 according to the card template and card style selected by the user, and draws the card foreground image and card foreground text set in the foreground layer in the card style. The card template includes but is not limited to the template unique identifier, card template, card back, card base, and manufacturing process. The card style includes the area segmentation structure of the card surface, the foreground image of the card surface, and the foreground text set of the card surface. When the mouse is pressed or the gesture touch start event is received, the foreground text set is searched first, and then the area set is searched. If the corresponding area is searched, the next step is processed, otherwise it is not processed.

[0044] Based on the content of the above method embodiment, as an optional embodiment, the personalized card display and production method provided in the embodiment of the present invention, the color space conversion includes: converting from RGB color space to CMYK color space.

[0045] Specifically, the rectangular area occupied by the text can be calculated through the parameters of the text set, and it is determined whether the point touched by the mouse or gesture is within the above rectangular area. If the point is within the rectangular area, the selected text is edited. The above rectangle is drawn in the area selection layer, and the rectangle is highlighted, such as Gaussian blurring the edge of the rectangle.

[0046] Based on the content of the above method embodiment, as an optional embodiment, the personalized card display and production method provided in the embodiment of the present invention, the parameter adjustment of the personalized picture according to the preview picture includes: adjusting the clarity and brightness of the personalized picture.

[0047] Check the clarity and brightness of the image in turn, and make personalized image color adjustments to compensate for the color deviation of the RGB to CMYK color space conversion. Specifically, you can use the following method to adjust the clarity of the image. De-noise the image through low-pass filtering, then smooth the image, use the Laplace operator to do convolution on the grayscale image, and calculate the standard deviation. When the standard deviation is small, reduce the noise through constrained least squares filtering; when the standard deviation is large, do not process it. Specifically, you can use the following method to adjust the brightness of the image. Use the mean and variance of the image on the grayscale image to determine whether the image is underexposed or overexposed. If it is underexposed or exposed normally, convert RGB to HSL color space, adjust the saturation and brightness of the image, and then convert HSL to RGB color space, and enhance the local contrast of the image through the Laplace operator; do not process overexposure.

[0048] Specifically, the selected text is edited in the foreground layer, including but not limited to changing text parameters and deleting text objects. If the clicked position is not within the rectangular area where the text set is located, the area set is searched.

[0049] Based on the content of the above method embodiment, as an optional embodiment, the personalized card display and production method provided in the embodiment of the present invention, the parameter adjustment of the canvas group also includes: describing the personalized picture in a pixel matrix, and the corresponding pixel matrix is:

[0050]

[0051] Among them, x is the horizontal coordinate of the pixel point; y is the vertical coordinate of the pixel point; x' is the horizontal coordinate of the pixel point after transformation; y' is the vertical coordinate of the pixel point after transformation; a, b, c, d, e, f are constraints.

[0052] Specifically, the area set is composed of closed polygons, and it is determined by judging whether the point touched by the mouse or gesture is within the above polygon. If the point is within the polygon of the area, the selected area is edited. The above polygon is drawn in the area selection layer, and the polygon is highlighted, and the custom picture is edited in the background layer. If there is no picture in the area, it will prompt to upload the picture. In order to solve the problem of operation jams caused by large pixels of pictures uploaded by users, the parameters of the uploaded pictures are checked, and the pictures are scaled proportionally according to the selected card surface and the aspect ratio of the picture. If the uploaded photos are taken by a camera, it is necessary to adjust the display direction of the photo according to Exif (Exchangeable image file format) and then scale it. If there is a picture, the picture in the area is edited, including but not limited to moving, scaling, rotating, mirroring, deleting pictures, and replacing areas. See further Figure 4 , each area of ​​the background layer is divided into 5 parts, the middle part S301 can be moved, scaled, rotated, and mirrored, and the area edges S302, S303, S304, and S305 are the left stretching area, the top stretching area, the right stretching area, and the bottom stretching area respectively. The stretching area at the edge of the area can automatically align the edges of the pictures in the area to solve the problem of difficult edge alignment when the screen is small.

[0053] Area replacement refers to exchanging the images in two areas. The images are moved in the selected area by the mouse or touch point to exchange the images in the two areas. When the mouse or touch point moves outside the selected area, the image in the selected area is cleared in the background layer, and other areas remain unchanged. The canvas of the area selection layer is cleared, and the image of the selected area is drawn in a reduced and translucent manner following the mouse or touch point. The polygon of the area where the mouse or touch point is located is drawn and highlighted. When the mouse is lifted or the touch ends, if the selected area is different from the area where the mouse or touch point is located, the images of the two areas are exchanged and scaled according to the aspect ratio; otherwise, no processing is performed. The background image information can be described by a pixel matrix to make image operations smoother. The pixel points in the image are defined as in formula (1), and the a, b, c, d, e, and f constraints of different basic transformations are different.

[0054] The unchanged constraints are:

[0055]

[0056] The constraints for horizontal mirroring are:

[0057]

[0058] The constraints for vertical mirroring are:

[0059]

[0060] The constraints for translation are:

[0061]

[0062] Among them, X is the horizontal axis movement distance; Y is the vertical axis movement distance.

[0063] The constraints when scaling are:

[0064]

[0065] Where W is the width of the image after scaling; H is the height of the image after scaling.

[0066] The constraints for rotation are:

[0067]

[0068] Here, θ is the angle of clockwise rotation.

[0069] You can also combine transformations. For example, the transformation matrix for simultaneous rotation and translation is:

[0070]

[0071] The image of the foreground layer and background layer canvas combination is the customized element of the personalized card. Create a new canvas with the same size as the canvas group and white fill color, draw the elements of the background layer and foreground layer canvas in turn, compress and save as a PNG format image.

[0072] Based on the content of the above method embodiment, as an optional embodiment, the personalized card display and production method provided in the embodiment of the present invention, the card template also includes: a hollow pattern for opening a hollow area.

[0073] Specifically, in order to prevent the picture that the user sees in the system from being inconsistent with the card face of the physical card, a personalized card face preview function is provided. That is, the adjusted personalized picture and the card face template are synthesized into an RGB image, imported into the ICC (International Color Consortium) file of the printer device, the RGB is converted into a PNG image in the CMYK color space, and chamfered according to the standard of the card face. According to the effect of the preview image, the user can select a filtering function to adjust the color of the card face. The filtering functions are all for processing PNG format images in the RGB color space.

[0074] See also Figure 5 , and better use 3D card preview, the preview image of the card surface, the back of the card, and the card base form a UV texture. The UV texture includes: S405 is a preview image of the card surface, S402, S403, S404, S405 are the card base, and S401 is the back of the card. Add this UV texture to the 3D card model. The user can use gestures to preview this 3D personalized card model in all directions. After the user confirms the preview, the finalized personalized picture in PNG format of RGB color space is stored in the database.

[0075] See also Figure 6 During the hollowing synthesis process, the card template can be divided into two parts, the hollowing diagram S501 and the template PDF file. The hollowing diagram S501 refers to the elements that cannot be directly printed on the card template. In order to prevent the multi-layer production of the card and the interference of the printed colors, this area needs to be removed before printing. For example, chips and some special processes, the said special processes include but are not limited to hot stamping, silk screen printing, and embossing. The production method can choose to use Illustrator software or Photoshop software to make the elements that cannot be directly printed in the card template into PNG images in RGB color space under multiple resolutions. There are multiple card templates corresponding to the same hollowing diagram. If the card template does not have elements that cannot be directly printed, the card template will not correspond to any hollowing diagram. The template PDF file refers to the elements that can be directly printed in the card template except the hollowing diagram. In the card printing specification, the elements of the card template need to be printed clearly, distortion is not allowed, and color deviation is not allowed. Therefore, the elements in the card template need to be vector and must be images in the CMYK color space. The production method can choose to use Illustrator software to draw the elements that can be directly printed in the card template into vector graphics in the CMYK color space and make it into a template PDF file. The card template and the template PDF file correspond one to one. Specifically, it can be described as follows: According to the card making file of the system, search for personalized pictures and card templates. Further hollow out the personalized pictures and hollowed-out pictures. Specifically, obtain the non-transparent pixels of the hollowed-out picture and make the pixels of the card template transparent. Hollowing out is mainly to clear the picture of the area that will be processed by the chip or special process to prevent color interference. Further determine whether the card is a vertical card. If it is a vertical card, rotate the hollowed-out PNG picture 90 degrees clockwise. Keep all vertical cards in the same direction to facilitate chip installation. Further import the ICC (International Color Consortium) file of the printer device, convert the RGB PNG picture to the CYMK color space, set the compression parameters and resolution to convert it into a JPEG format picture. Whether there is a picture to be synthesized, further synthesize the JPEG format picture in the previous step with the template PDF. Specifically, a PDF file is created, the document size of the PDF is set to the size of the personalized JPEG format image, the personalized JPEG format image is added to the PDF file, and then the template PDF content is drawn on the current page at the position with the absolute coordinates (0, 0).

[0076] The personalized card display and production method provided by the embodiment of the present invention creates a canvas group, adjusts the parameters of the canvas group, and hollows out the hollowed-out surface; converts the layout mode and color mode of the hollowed-out card template, and synthesizes the format surface and the template format to obtain a personalized card. The color difference can be eliminated while maintaining the consistency of the card surface, and the personalized picture is aligned with the edge of the card surface template, which greatly simplifies the operation difficulty, can process pictures in batches, and effectively reduces the production cost of personalized cards.

[0077] The implementation basis of each embodiment of the present invention is to implement programmed processing through a device with a processor function. Therefore, in engineering practice, the technical solutions and functions of each embodiment of the present invention can be encapsulated into various modules. Based on this reality, on the basis of the above embodiments, the embodiment of the present invention provides a personalized card display and production device, which is used to execute the personalized card display and production method in the above method embodiment.

[0078] The parameter adjustment module 701 is used to receive a personality picture and a card template, perform color space conversion on the personality picture to obtain a first personality picture, synthesize the first personality picture and the card template in a canvas group to obtain a preview picture, and perform parameter adjustment on the personality picture according to the preview picture to obtain a second personality picture;

[0079] The card synthesis module 702 is used to determine that the layout of the second personalized picture and the card template is horizontal, then the second personalized picture and the card template are converted into a color space to obtain a third personalized picture and a first card template, and the third personalized picture and the first card template are synthesized to obtain a personalized card.

[0080] The personalized card display and production device provided in the embodiment of the present invention adopts a parameter adjustment module and a card synthesis module. By creating a canvas group, the parameters of the canvas group are adjusted, and the hollowed-out surface is hollowed out; the layout mode and color mode of the hollowed-out card template are converted, and the format surface and the template format are synthesized to obtain a personalized card. The color difference can be eliminated while maintaining the consistency of the card surface, and the personalized picture is aligned with the edge of the card surface template, which greatly simplifies the operation difficulty, can perform batch processing of pictures, and effectively reduces the production cost of personalized cards.
