Problems solved by technology

[0006] According to the analysis of the above literature, it can be seen that the existing literature research on LED punching luminous characters is mostly focused on its production process, materials or technology, and there are almost no reports on how to automatically and evenly arrange LED bulbs (holes) on the characters.

Embodiment

[0063] A typical implementation example of the present invention is as follows:

[0064] 1. The word to be processed in this example is the word "symbol", in which the word "xiang" is in italics, and the word "sign" is in bold, such as Figure 5 As shown, the outline of the italic font is smooth, and the outline of the bold font is sharp. The size of two characters is about 1500mm×900mm.

[0065] 2. above-mentioned two words are imported in the test program written by the inventive method with C++ language.

[0066] 3. In the test program, set R=3mm, D b = 3mm, D ave = 15mm, D min = 9 mm.

[0067] Figure 5 The result of automatically generating a series of hole positions for the word "symbol" is given. Depend on Figure 5 It can be seen that, firstly, the present invention can better deal with the problem of discrete curves and maintain the shape of the original characters, and secondly, it can generate uniformly arranged holes with clear veins inside the characters. ...

Abstract

The invention discloses a method for uniformly distributing holes in a light-emitting word based on contour offset. The method comprises the following steps: inputting a contour file to be processed, wherein the hole radius is R, an average interval between every two holes is Dave, a minimum interval is Dmin, and a distance between each hole and a contour boundary is Db; dispersing a contour curve group into a polygon group and calibrating the direction of each polygon; continuously offsetting the polygon group, wherein a first-time offset distance is Db, and a subsequent offset distance is Dave; generating a series of holes on each offset polygon at intervals Dave, wherein the circle centers of the holes are arranged on the offset polygon, and the radius is R; detecting a distance between every two obtained adjacent holes and deleting one of the holes when an interval between any two practical holes is less than a given Dmin value. The method has the benefits that the holes are distributed at equal distances in an offsetting way, the positions of the obtained holes are uniformly distributed and clear in arrangement, and the situation that the holes are overlapped or the interval is undersize can be avoided.

Description

technical field [0001] The invention relates to the field of evenly distributing holes in contours, in particular to a method for uniformly distributing holes in luminous characters based on contour offset. Background technique [0002] In the modern society with the rapid development of science and technology, outdoor advertising has introduced many new materials, new technologies, and new equipment, and has become a kind of art to beautify the city, and it is one of the signs of the city's economic development. Traditional outdoor advertising logo fonts mainly use neon lights, fluorescent tubes or high-power chemical gas bulbs as the main light source. The light source is generally built in a closed light box, which requires a high-voltage power supply to make it glow. The heat is serious, which is about twice the power consumption of light. , and the heat is difficult to dissipate in the airtight box, and long-term high temperature will easily lead to a decrease in the li...
