It should be noted that the e-commerce platform user client may be installed on a terminal, and a user may implement interaction with the e-commerce platform user client through the terminal.
S102: and determining the embroidery needle path adopted when the color image is embroidered by the embroidery machine.
In the present invention, an embroidery machine is a device for forming an image on an embroidery product.
In an alternative embodiment of the present disclosure, the pattern in the color map may be composed of a plurality of sub-regions, wherein the colors of two adjacent sub-regions are different. That is, the sub-regions in the present invention are used to distinguish the locations of different colors in the color map. Regarding each sub-area in the color chart, taking one point on the edge of the sub-area as a starting point of embroidery, taking one point on the other edge as an end point of embroidery, and taking a needle path between the starting point and the end point as a sub-needle path. And taking the starting point as a middle point, the end point as a new starting point, and taking a point which is spaced from the middle point by the embroidery thread width as a new end point. And taking the needle path between the new starting point and the new end point as another sub-needle path until the obtained sub-needle paths are fully distributed in the sub-areas. Then, each sub-needle path is set as an embroidery needle path.
In the present invention, the embroidery stitch is a path taken when the embroidery machine embroiders the closer color map in the area corresponding to the customized area. In the present invention, the embroidery stitch may be characterized by information of the embroidery stitch. Wherein, the information of the embroidery needle path may include at least one of the following: the embroidery product is corresponding to the color of the embroidery thread adopted under the condition of the pattern depending on the color chart, the pixel width of the embroidery needle path and the position of the embroidery needle path on the embroidery product.
Illustratively, the embroidery path obtained by the process in this specification may be represented by: < path d ═ M0, 0-45,290, -5-45,230, -11-45,170, -16-45,120, -21-45, 60, -27-45, 00, -32-45, -60, -37-45, -120, -43-45, -170, -48-45, -230, -53-45, -290, -58-45
… … (ignoring part of the connection points here)
-47,-405 14,-391 -48,-411 17,-394 -48,-416 20,-396 -48,-422 23,-398 -48,-427 26,-400 -48,-433 29,-403 -49,-438"fill＝"none"stroke＝"#0b2d4f"stroke-width＝"3"/>
Therefore, the embroidery stitch is generated by the process of the invention according to the color chart, and the information of the embroidery stitch contains the color of the embroidery thread, so that the color of the embroidery product generated when the embroidery machine performs the embroidery can be embodied. In addition, excessive manual intervention is not needed in the process of the invention, which is beneficial to reducing the error of the generated embroidery needle path and improving the efficiency of generating the embroidery needle path.
In an optional embodiment of the present invention, after obtaining the embroidery stitch, the present invention may further process the color map according to the embroidery stitch to obtain a processed image, where the processed image is used to generate an identifiable embroidery file of the embroidery machine, and the processed image may include an SVG image. SVG is an image file format, which is called Scalable Vector Graphics in english, and means Scalable Vector Graphics. It is an open standard vector graphics language developed by World Wide Web Consortium (W3C) alliance based on XML (extensible Markup language). The user can directly draw the image with the code, open the SVG image with any word processing tool, make the image have interactive function by changing part of the code, and can insert into HTML at any time to watch through a browser.
In the present invention, the color map can embody the color of the image on the embroidery product obtained under the condition of the color of the embroidery thread provided at the merchant end. The process of generating the reliable color map may be acquiring an embroidery image. And screening out colors with the difference value smaller than a color threshold value from the color set aiming at each color in the embroidery image. And replacing the corresponding color in the embroidery image with the screened color to obtain a color-dependent map. It can be seen that the colors of some sub-areas in the reliable color map in the present description may be different from the colors of the corresponding sub-areas in the embroidery image, but the difference is not too large. That is, the color chart in the present invention may not necessarily be exactly the same as the embroidery image, but the color chart is an image that is closer to the embroidery image at least in color when embroidery is performed under the embroidery condition provided by the embroidery machine (the embroidery condition may be determined to some extent by the color of the embroidery thread).
In an alternative embodiment, the user may have his own image as an embroidery image and upload it through the e-commerce platform user client. For another example, in another optional embodiment, a terminal where the e-commerce platform user client is located may store a plurality of alternative images in advance, and the user may select the uploaded image to be customized for embroidery in the terminal through the e-commerce platform user client.
In the related art, a customized embroidery product may include a plurality of faces to be embroidered, the size of a customized area of different faces may be different, and the size of the customized area may also be different from the size of an embroidery image provided by a user (buyer), so that a white border may exist on the embroidery product obtained by embroidery at a position corresponding to the embroidery image.
In an alternative embodiment of the invention, to avoid white edges on the customized product, first, the physical size and the predetermined resolution of the customized area are determined. Then, taking the product of the physical size and the preset resolution as the pixel size of the customization area; converting the reliable color map into an intermediate image matched with the pixel size of the customized area. And determining the embroidery needle path adopted when the intermediate image is embroidered by the embroidery machine. When the customization area is customized for embroidery, the customization area may also be understood as an embroidery area. In the process of three-dimensional modeling of the product, the user can customize the product in the customization area, such as customizing images, characters and the like in the customization area.
In addition, the process in the present invention may also determine the pixel size of the customized region in other manners, which is not described herein again.
In an actual scene, there may be a case where the pixel sizes of the reliable color charts employed each time the embroidery effect chart generation process is executed are different, and it is necessary to determine the pixel sizes of the reliable color charts after the reliable color charts are acquired. In an alternative embodiment of the present invention, the attribute information of the color map, which includes the pixel size, may be read by image software.
Alternatively, the transformation may be performed by establishing a first pixel coordinate system (e.g., a euclidean coordinate system) within the custom region, and determining a first coordinate position of a first designated pixel (any pixel in the custom region that is not on the origin of coordinates) in the first pixel coordinate system. And determining the ratio of the distances of the first designated pixel from at least three edges of the customized area according to the first coordinate position as a designated ratio.
Then, a second pixel coordinate system is established in the color-leaning graph, and the point, with the same ratio of the distances from at least three sides of the color-leaning graph and the specified ratio, in the color-leaning graph is determined as a second specified pixel. A second coordinate position of the second designated pixel in the second pixel coordinate system is determined. And establishing a coordinate transformation matrix according to the proportional relation between the first coordinate position and the second coordinate position.
And then, for each pixel in the color-dependent map, multiplying the coordinate of the pixel in the second pixel coordinate system by the coordinate conversion matrix to obtain the coordinate of the pixel in the first pixel coordinate system. And adding the pixel to the coordinate of the pixel in the first pixel coordinate system to obtain an intermediate image. The intermediate image has the same pixel size as the custom area.
It should be noted that there may be other methods for implementing the conversion, and the present invention is not limited to this.
The processed image can be used for meeting the production requirements of merchants, namely after the merchants obtain the processed image, the processed image can be input into specified software to obtain the recognizable embroidery files of the embroidery machine. The embroidery needle path may be a coordinate position, a line width ("stroke-width", a distance between lines embroidered by adjacent two needles), and a color ("stroke") of an embroidery thread, which are used when the needle performs embroidery in the customized area. For example, when the embroidery machine is an embroidery machine, the embroidery needle path is data of a plurality of coordinate positions, and the coordinate position represented in the embroidery needle path is the position where the embroidery needle falls.
In addition, the processed image can be used for displaying embroidery effect to a user, and specifically, the color map can be rendered according to the embroidery path to obtain an embroidery effect map. The rendering mode can be that an embroidery path is added to the color-dependent map to obtain an embroidery effect map. The embroidery path is shown in the embroidery effect picture, so that the user can intuitively know the obtained effect of the embroidery needle path in the embroidery product from the embroidery effect picture so as to be convenient for making the next decision.
The embroidery needle path generation method is applicable to a C2M mode and a C2M (Customer-to-factory) mode, namely a mode that a user directly connects a manufacturer, namely a Customer directly to a factory, and emphasizes the connection between the manufacturer and the Customer. In the C2M mode, the customer places an order directly through the platform, and the factory receives the customer's order and then designs, purchases, produces, and ships as required. The C2M model is also called an economic model, short-circuits all intermediate processes such as stock, logistics, total sales, distribution and the like which can be short-circuited, cuts down all unnecessary cost including the stock, allows users to purchase ultra-high quality products at ultra-low price, and allows the manufacturing industry to directly face the user's requirements.
