Embodiment 1

[0064] See figure 1 , the present embodiment provides an inkjet printing method for image segment transformation, the method is used to convert an original image into a target image for printing, and mainly includes the following steps:

[0065] S1: Solve the forward transformation matrix according to the original image information and the actual positioning point data and / or transformation information;

[0066] S2: Determine the edge point, width and height of the target image according to the original image information and the forward transformation matrix;

[0067] S3: Solve the inverse transformation matrix according to the original image information and the edge point of the target image;

[0068] S4: segmentally convert the original image into the target image according to the inverse transformation matrix;

[0069] S5: Print the target image in segments.

[0070] When printing the PCB, first place the PCB board on the printing platform of the printing device, and the...

Embodiment 2

[0123] This embodiment is a further improvement on the basis of Embodiment 1. For some examples in Embodiment 1, only one application is used to store a currently converted sub-original image and a converted sub-target image. In the case of storage resources, this embodiment is at S41: divide the original image into multiple sub-original images according to the inverse transformation matrix, and each sub-original image corresponds to a sub-target image, and the target image is composed of the sub-target images and S42: Application for storing the data of one of the sub-original images between the first storage area and the second storage area for storing the data of the sub-target image corresponding to the sub-original image further includes:

[0124] S410: Determine the maximum storage capacity C required to store a single sub-original image according to the row number N of the sub-target image, the inverse transformation matrix, the width of the original image, and the heigh...

Embodiment 3

[0141] see Figure 9 , an embodiment of the present invention provides an inkjet printing device for image segmentation conversion, the device includes:

[0142] A forward transformation matrix solving module, the forward transformation matrix solving module is used to solve the forward transformation matrix according to the original image information and the positioning point data and / or the conversion information;

[0143] A target image parameter determination module, the target image parameter determination module is used to determine the edge point, width and height of the target image according to the original image information and the forward transformation matrix;

[0144] An inverse transformation matrix solving module, the inverse transformation matrix solving module is used to solve the inverse transformation matrix according to the original image information and the most edge point of the target image;

[0145] An original image segment conversion module, the targ...

Abstract

The invention discloses an ink-jet printing method and device for image segmentation transformation, equipment and a storage medium, and relates to the technical field of ink-jet printing. The image segmentation transformation ink-jet printing method comprises the following steps: solving a forward transformation matrix; determining the edge point, the width and the height of the target image; solving an inverse transformation matrix; segmenting and converting the original image into a target image; and printing the target image in sections. The printing device comprises a forward transformation matrix solving module, a target image parameter determining module, a reverse transformation matrix solving module, an original image segmentation conversion module and a target image segmentation printing module. The printing device includes a processor, a memory, and computer program instructions stored in the memory. And computer program instructions are stored in the storage medium. According to the ink-jet printing method and device for image segmentation transformation, the equipment and the medium, the placement error of the printing object can be corrected, the printing time is shortened, and the printing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to an inkjet printing method, device, equipment and storage medium for image segmentation conversion. Background technique [0002] Inkjet printing technology refers to the technology of spraying ink droplets onto the printing object through the nozzle to obtain images or characters. This technology is non-contact printing, which has the characteristics of fast printing speed, low pollution and high printing accuracy. [0003] In some printing scenarios, the position, size, angle, etc. of the actual target image to be printed and the original image used as the source of the printing data are different due to the error in the placement of the printing object. At this time, the original image needs to be transformed. Print after obtaining the target image. For example, when printing a PCB, the position or posture of the actual PCB board is different from the original image. ...
