Problems solved by technology

In the prior art, there are also many image processing software, such as Meitu Xiuxiu, Photoshop and other tools. This image processing tool can only realize the "display" effect of the image, and cannot obtain a well-defined relief image suitable for laser engraving.
The sketch image generated by the image processing software in the prior art is used to engrave the picture on the micro-engraving machine, which has the defects of unclear outline, too many noise points, poor sense of space, primary and secondary, and layering

Embodiment 1

[0084] An image processing method for obtaining an embossed retro effect suitable for laser engraving, comprising: obtaining the effect of strengthening the edge according to the original image P respectively Figure X T and obtain the effect map VO of color and edge balance; then the effect Figure X Multiply T with the effect image V0 to obtain the mixed effect image OS, and then normalize the gray scale of the mixed effect image OS to the range of 0-255 to obtain the final relief retro effect image O.

[0085] Among them, the effect of strengthening the edge is obtained according to the original image P Figure X T is specifically carried out through the following steps:

[0086] S1, the original image P is separated into three independent channel images, and the red channel image A1, the green channel image A2 and the blue channel image A3 are respectively obtained; step S1 can divide the original image P into red channel images A1, A1, and A3 through the opencv function spl...

Embodiment 2

[0139] The method for obtaining the image processing method for embossing retro effects suitable for laser engraving will be further described in conjunction with specific examples.

[0140] by image 3 The color original image shown is the original image P, and the three-channel RGB original image P is divided into red channel image A1, green channel image A2 and blue channel image A3 by using the opencv function split, as shown in Figure 4 , Figure 5 , Image 6 shown.

[0141] S2, convert the original image P into a grayscale image H, such as Figure 7 shown. Normalize the grayscale image H to obtain a normalized image U, such as Figure 8 As shown, and invert the normalized image U to get the inverse image F, such as Figure 9 shown.

[0142] S3, Gaussian filtering is performed on the inverse color image F, and such as Figure 10 The Gaussian-filtered image shown is inverted to obtain an image M, and then the normalized image U obtained in step S2 is divided by th...

Abstract

An image processing method for obtaining a relief retro effect suitable for laser engraving obtains an effect image XT of an enhanced edge and an effect image VO of color and edge equalization respectively according to an original image P. Then multiplying the effect map XT by the effect map V0, the mixed effect map OS is obtained, and the mixed effect map OS is normalized to 0-255, to obtain thefinal relief retro effect drawing O. The method can be used to obtain a clear outline, hierarchical relief retro effect map. The relief retro effect picture obtained by the method of the invention canbe carved by an engraving machine to obtain the relief retro effect picture with clear image outline, space feeling, primary and secondary feeling, good sense of hierarchy, prominent detail and natural color transition.

Description

technical field [0001] The invention relates to the technical field of laser engraving, in particular to an image processing method for obtaining an embossed retro effect suitable for laser engraving. Background technique [0002] Pictures or photos often leave people with many good memories. With the continuous development of technology, various artistic pictures or photos emerge in endlessly. Traditional pictures are often flat-effect pictures. With the development of engraving equipment and engraving technology, laser engraving images can be realized through laser micro-engraving machines, and the engraving effect of pictures can be realized more. [0003] In the prior art, laser engraving images are usually output by computers or mobile storage devices, and under the control of the main control chip, the engraving mechanism performs engraving according to the transmitted images. Because, the effect of the delivered picture directly determines whether the outline of the...
