Method for uniformly distributing holes in light-emitting word based on contour offset

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...

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.
