Embodiment 1

[0034] like figure 1 Shown, a kind of BMP image processing method for laser seal engraving machine comprises the steps:

[0035] 1. Obtain the initial BMP image of the seal to be engraved that contains the security thread and the initial BMP image that does not contain the security thread, and read the data information respectively.

[0036] like figure 2 As shown, the schematic diagram of the initial BMP image containing the anti-counterfeiting thread of the seal to be engraved. The method for obtaining it is to adopt the method in the prior art.

[0037] 2. The overall thickening process of the initial BMP image that contains the anti-counterfeiting line obtains the BMP image that contains the anti-counterfeiting line after the overall thickening process; and keeps the pixel number of the BMP image that contains the anti-counterfeiting line after the described overall thickening process Consistent with the number of pixels of the initial BMP image containing the security...

Embodiment 2

[0068] An embodiment of the present invention provides a BMP image processing terminal device for a laser seal engraving machine. The terminal device in this embodiment includes: a processor, a memory, and a computer program stored in the memory and operable on the processor, such as an anti-counterfeiting thread restoring program. When the processor executes the computer program, the steps in the embodiments of the BMP image processing method for the laser seal engraving machine in the above-mentioned embodiment 1 are realized, for example figure 1 The steps shown: Obtain the initial BMP image containing the security thread and the initial BMP image not containing the security thread of the seal to be engraved, and read the data information respectively. Or, when the processor executes the computer program, it realizes the functions of each module / unit in the above-mentioned device embodiments, for example: obtaining the initial BMP image of the seal to be engraved that conta...

Embodiment 3

[0078] If the integrated module / unit of the BMP image processing terminal equipment used for the laser seal engraving machine is realized in the form of a software function unit and sold or used as an independent product, it can be stored in a computer-readable storage medium. Based on this understanding, the present invention realizes all or part of the processes in the methods of the above embodiments, and can also be completed by instructing related hardware through a computer program. The computer program can be stored in a computer-readable storage medium, and the computer When the program is executed by the processor, the steps in the above-mentioned various method embodiments can be realized. Wherein, the computer program includes computer program code, and the computer program code may be in the form of source code, object code, executable file or some intermediate form. The computer-readable medium may include: any entity or device capable of carrying the computer pro...

Abstract

The invention provides a BMP image processing method for a laser seal engraving machine. The method is characterized by comprising the following steps of obtaining an initial BMP image including a security thread and an initial BMP image not including a security thread of a seal to be engraved and respectively reading data information, performing overall bold processing on the initial BMP image including the security thread to obtain an overall bolded BMP image including the security thread, maintaining the number of pixels of the overall bolded BMP image including the security thread to be the same with the number of pixels of the initial BMP image including the security thread, determining whether to compress the overall bolded BMP image including the security thread, and restoring the security thread of the overall bolded BMP image including the security thread to obtain a BMP image used by the laser seal engraving machine in engraving. Through the processing method provided by thepresent invention, the BMP image of a seal is processed, the BMP image has a clear font, the security thread is clear, and the seal engraving is prepared.

Description

technical field [0001] The invention relates to the technical field of image processing for laser seal engraving machines, in particular to a BMP image processing method for laser seal engraving machines. Background technique [0002] As we all know, my country is a big country that uses seals. Seals are inseparable items in people's daily life and work. Seals represent the legal identity of groups, units and individuals on many occasions. In foreign countries, some countries such as Japan and Southeast Asian countries are also using seals. [0003] For a long time, the production of seals has been entirely dependent on manual carving, which has low efficiency, high labor intensity, and irregular fonts, which are far from meeting the fast-paced and high-efficiency development needs of contemporary society. For this reason, seal engraving needs to update technology. After several generations of hard work, the engraving process and equipment have been constantly updated, esp...
