To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the invention.

[0046] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0047] Example 1

[0048] This invention provides a zone recognition printing method applicable to inkjet printing equipment. The inkjet printing equipment includes a printing platform and at least one printhead, each printhead comprising at least one row of nozzles for ejecting ink. The inkjet printing equipment also includes an image acquisition device, which can be a line scan camera or an area scan camera. The image acquisition device is connected to a host computer (such as a PC) of the inkjet printing equipment via wired or wireless means. It can send acquired images to the host computer for image processing and can also receive control information from the host computer and adjust the acquisition range and parameters accordingly to perform corresponding image acquisition.

[0049] Please see Figure 1 The partition recognition and printing method specifically includes the following steps:

[0050] S1: Divide the printing platform into several printing areas, and place several printing media in each of the printing areas. The printing media in the same printing area have the same printed image.

[0051] S2: Control the image acquisition device to acquire an image of the printing platform and obtain a first acquired image;

[0052] S3: Obtain the position information and placement orientation of the printing medium based on the first acquired image;

[0053] S4: Obtain image printing data corresponding to the printing medium based on the location information and placement orientation;

[0054] S5: Control the printhead to perform inkjet printing on the printing medium according to the image printing data and the position information.

[0055] Specifically, multiple printable media may be of the same type but have different images to be printed on them, or the printable media may be divided into several groups, with printable media in the same group having the same image to be printed, but printable media in different groups having different images to be printed, or the printable media may be of different types, with different images to be printed on them. To ensure that all these printable media are printed correctly, in this embodiment of the invention, the printing platform is divided into printing areas, with the printable images of the media within the same printing area being identical. In one embodiment, when the printable media are of the same type but the corresponding printable images are not completely identical, the printing platform is divided into several different printing areas according to the different printable images. For example, as shown... Figure 2 As shown, the printing media are all bottle caps of the same type, but some bottle caps need to be printed with red images, some with blue images, and others with green images. Therefore, the printing platform is divided into three printing areas based on the different printed images: a red image printing area, a blue image printing area, and a green image printing area. In one embodiment, when the printing media are of different types and the corresponding printed images differ, the printing platform is divided into different printing areas according to the type of printing media. For example, as shown... Figure 3As shown, the printing media includes two types: bottle caps and triangular badges. Different types of printing media correspond to different printed images; for example, bottle caps are printed with yellow images, and triangular badges with purple images. In this case, the printing platform is divided into two different printing areas: one for bottle caps and one for triangular badges, with different printed images for each area. In other embodiments, after partitioning the printing platform according to the type of printing media, if the printed images of the same type of printing media are not entirely the same, the printing area can be further divided into several sub-printing areas based on different printed images. For example, the printing media includes two types: bottle caps and triangular badges. After dividing the printing platform into two printing areas corresponding to bottle caps and triangular badges, if the printed images corresponding to bottle caps are not entirely the same, then the printing area corresponding to bottle caps can be further divided into multiple sub-printing areas based on different printed images. In some embodiments, the printing platform is divided into printing areas according to the number of printing areas in a uniform and regular manner. For example… Figure 2 As shown, the printing platform is evenly and regularly divided into three printing zones. In some embodiments, the division can also be based on the amount of printing media contained in each printing zone, such as... Figure 3 As shown, there are more bottle caps with yellow images and fewer triangular badges with purple images. Therefore, the printing area for placing bottle caps can be larger than the printing area for placing triangular badges.

[0056] After dividing the printing platform into several printing areas, the image acquisition device is controlled to acquire an overall image of the printing platform to obtain a first acquired image. The position information of each printing medium is then obtained based on the first acquired image. Preferably, obtaining the position information and placement orientation of the printing medium based on the first acquired image includes:

[0057] The first acquired image is subjected to image recognition processing to obtain the image corresponding to the printing medium, which is denoted as the printing medium image;

[0058] Obtain the image coordinates and orientation information of the printed medium image in the first acquired image;

[0059] The position and orientation of the printing medium on the printing platform are obtained based on the image coordinate information and orientation information.

[0060] Specifically, image recognition processing is performed on the first acquired image to extract the images of each printing medium and obtain the image coordinate information and orientation information of each printing medium image in the coordinate system of the first acquired image. This coordinate information and orientation information in the coordinate system of the first acquired image are then converted into coordinate information and orientation information in the coordinate system of the printing platform, thus obtaining the position information and placement orientation of the printing medium. For example, such as... Figure 3 and Figure 4 As shown, when the printing medium 10 is a triangular badge, the left vertex of the smallest bounding rectangle of the corresponding printing medium image 20 has image coordinate information (x1, y2) in the first acquired image, and its direction R is at an angle α with the y-axis in the coordinate system of the first acquired image. This image coordinate information is converted into the corresponding coordinate information (X1, Y2) on the printing platform, and its placement direction is at an angle α with the y-axis of the printing platform.

[0061] After obtaining the location information and placement orientation of the printing medium, preferably, obtaining the image printing data corresponding to the printing medium based on the location information and placement orientation includes:

[0062] The printing area where the printing medium is located is determined based on the location information;

[0063] The corresponding printed image is determined based on the printing area where the printing medium is located.

[0064] Adjust the orientation of the printed image according to the placement orientation to obtain a calibrated printed image;

[0065] The calibration printed image is rasterized to obtain the image printing data.

[0066] Specifically, the printing area where the printing media is located can be determined based on the location information of the printing media. Since each printing area has its own corresponding printed image, the printed image corresponding to the printing media in the same printing area is the same. Before printing, the correspondence between each printing area and the printed image is established. For example, Figure 3As shown, the printed image corresponding to printing area 11 is a yellow image, and the printed image corresponding to printing area 12 is a purple image. Based on the position information of the printing medium 10, it is known that it is in printing area 12. Therefore, the red image corresponding to printing area 12 is obtained as the printed image. Furthermore, since the placement direction of the printing medium is arbitrary and does not need to be fixed, the printed image needs to be rotated according to its actual placement direction to ensure correct printing on the printing medium. For example, the angle α between the placement direction of the printing medium 10 and the Y-axis of the printing platform is obtained. Correspondingly, the printed image is rotated by the corresponding angle to obtain a calibration printed image. This calibration printed image is sent to the host computer of the inkjet printer for rasterization processing to obtain the image printing data corresponding to the printing medium 10.

[0067] After obtaining the image printing data corresponding to the printing medium, the image printing data and the position information of the printing medium are sent to the printhead. The printhead locates the printing medium according to the position information and performs inkjet printing according to its image printing data, thereby correctly printing the image on the surface of the printing medium.

[0068] In one embodiment, prior to controlling the printhead to inkjet print the printing medium based on the image printing data and the position information, the following steps are included:

[0069] The type of the printing medium is determined based on the printing area where the printing medium is located;

[0070] The distance between the printhead and the printing platform when printing in its designated printing area is determined based on the type of printing medium.

[0071] Since the printing media placed on the printing platform may be of various types, such as flat paper or labels, badges, phone cases, or bottle caps of a certain height, the height (distance) of the printhead relative to the printing platform is adjusted accordingly when printing different types and heights of printing media to avoid damage caused by the printhead touching the printing media. In this embodiment of the invention, printing media of the same type are divided into the same printing area. Therefore, when inkjet printing on various printing media in the same printing area, printing can be performed at the adjusted height. When entering the next printing area, the height of the printhead (relative to the printing platform) is adjusted according to the type of printing media in that printing area. In one embodiment, the heights of various types of printing media can be collected in advance and stored in a storage module. After obtaining the type of printing media in the printing area to be printed, the height of that type of printing media is read from the storage module. After obtaining the height of the type of printing media, a preset distance is maintained between the printheads of the printing media, for example, 0.5 mm. Then, the distance between the printing platform and the printhead is adjusted according to the height of the type of printing media and the preset distance, which is the sum of the height of the type of printing media and the preset distance.

[0072] During printing, the printing order of each printing area can be determined according to the actual situation. In some embodiments, such as... Figure 2 When the printing platform is divided into three printing areas along the Y-axis from top to bottom, the printing media in each of the three printing areas are printed sequentially from bottom to top or from top to bottom. In some embodiments, the printing order of each printing area can be determined based on the type and quantity of printing media in each printing area, or the data volume of the corresponding printed image. For example, printing areas containing fewer printing media are placed earlier in the printing order, and printing areas with smaller printed image data volumes are placed earlier in the printing order. In practical printing applications, the printing order of each printing area can be determined comprehensively based on the above factors to further improve printing efficiency.

[0073] In summary, the partition recognition printing method provided by this invention divides the printing platform into several printing areas, places several printing media in each printing area, and ensures that the printing images corresponding to the printing media in the same printing area are identical. The method controls an image acquisition device to acquire images of the printing platform to obtain a first acquired image; obtains the position information and placement orientation of the printing media based on the first acquired image; obtains image printing data corresponding to the printing media based on the position information and placement orientation; and controls the printhead to perform inkjet printing on the printing media based on the image printing data and the position information. This method, by dividing the printing platform into several printing areas, ensures the consistency of the printed images of the printing media within the same printing area, thus improving printing accuracy and stability. Furthermore, it can simultaneously handle the printing needs of multiple printing media with different images, increasing printing flexibility and diversity, and helping to meet users' personalized needs.
