Embodiment 1

[0040] Combine Figure 1 to Figure 3 A detailed description will be given of a method for depicting a microstructure texture based on grayscale processing in this embodiment.

[0041] According to the needs of the fineness of the image, the resolution of the image is generally selected as 500-1000dpi. In this embodiment, 508dpi is selected, that is, there are 508 pixels per inch. In this embodiment, the microstructure is selected as a regular quadrangular pyramid, the side length of the bottom of the regular quadrangular pyramid is the size of each pixel, and the size of the pixel is 25400um / 508=50um.

[0042] Determine the size of the vertex angle of the regular quadrangular pyramid: make a series of 30mm*30mm test boards in sequence, and each test board is arranged in a full plate with a size of 50um quadrangular pyramids on the bottom side. The depth of the regular quadrangular pyramids takes different values ​​from large to small. The depths of the square pyramids provided on...

Embodiment 2

[0046] Combine figure 1 with figure 2 A detailed description will be given of a method for depicting a microstructure texture based on grayscale processing in this embodiment.

[0047] According to the needs of the fineness of the image, the resolution of the image is generally selected as 500-1000dpi. In this embodiment, 1000dpi is selected, that is, there are 1000 pixels per inch. In this embodiment, the microstructure is selected as a cone, the diameter of the bottom of the cone is the size of each pixel, and the size of the pixel is 25400um / 1000=25.4um.

[0048] The determination of the vertex angle of the regular quadrangular pyramid: a series of 30mm*30mm test boards are made in sequence, and each test board is fully arranged with cones with a bottom diameter of 25.4um. The depth of the cones varies from large to small, and each test The depths of the cones provided on the plate are the same. And determine the brightness range that passes the test board, that is, the maxi...

Abstract

The invention discloses a microstructure texture characterization method based on gray-scale processing, comprising the following steps: determining a maximum vertex angle and a minimum vertex angle of the microstructure; Input a gray-scale image; Calculating the pixel gray value of the gray-scale image according to the formula to calculate the vertex angle of the microstructure; Determine the bottom size of the microstructure: determine the required image resolution, according to the image resolution, determine the bottom size of the microstructure; The microstructure texture of the photoresist plate is characterized by exposure development. The invention relates to a microstructure texture characterization method based on gray scale processing. After determining the maximum vertex angleand the minimum vertex angle of the microstructure according to the brightness, the resolution determines the bottom surface size of the microstructure to replace the current pixel. Thus, pixels withdifferent gray values can be replaced by pyramids or cones with different vertices, which can produce special light and shadow effects. It makes the image product made by the microstructure texture characterization method more simple and efficient, and the pattern is clearer.

Description

Technical field [0001] The invention relates to the technical field of image processing, in particular to a method for depicting microstructure texture based on grayscale processing. Background technique [0002] In LED or other visualized electronic products, it is sometimes necessary to display special light and shadow effects. The conventional production method has complicated steps, high cost and low efficiency, and the produced image products with special light and shadow effects are not clear enough. Moreover, the current image products with special light and shadow effects emit light with higher brightness, which has a greater damage to human eyes. Summary of the invention [0003] The purpose of the present invention is to provide a micro-structure texture characterization method based on gray-scale processing, which can produce image products with special light and shadow effects more simply and efficiently. [0004] In order to solve the above technical problems, the pur...
