【摘要】：在科技越来越发达的今天,激光技术逐渐成为我们生活中不可或缺的一项新型科技。从军事领域到医疗领域,从工业设备到商业应用,我们的日常生活中越来越离不开激光标刻技术的支持。从20世纪末人们发明激光以来,它的作用就一直没有被取代过。在人们发明了半导体、原子能、计算机之后,激光技术作为第四大发明逐渐走上了历史的舞台。它的测量精度高,切割技术快而准,光子能量大而稳,可以用作工业测量,材料切割以及光源发光。由于其高能量的特性,使得激光在国内外各大领域的应用都极其的广泛。近些年来,激光标刻技术逐渐被人们所重视。激光标刻技术是利用激光高能量的特性在材料表面进行图形图案的标刻,是激光技术中最重要的应用之一。激光标刻所作用的材料范围非常的广泛,从各种金属材料,如工厂的轴承、各种五金工具,到各式各样的非金属材料,如木材家具的标刻、玻璃的标刻、陶瓷布料的标刻、塑料饰品的标刻、橡胶工具的标刻等等,实现标记任意图像、文字、条形码、二维码,实现标刻序列号、批号、日期。激光所标刻的字符甚至可以小到微米级别,对商品的防伪标记有着无可替代的重要用途。激光标刻除了作用的材料范围广之外,其可以打标的图案的范围也是非常广的,在这些图案中,尤其以汉字的标刻最为重要。汉字的标刻主要应用在工业领域,由于激光对材料的标记有着不可逆转的特性,对于商品的标记,产品的防伪都有着无法超越的意义。通过激光标刻文字,不仅效率高,而且清晰易懂,对于材料的损害小,对于保持产品的美观程度有着极大的帮助。本文在激光标刻的背景下,实现激光标刻汉字的第一个步骤,即提取汉字的轮廓。本文的目的是在Visual Studio的环境下,利用VC++语言,使用计算机图形学中的二次贝塞尔曲线和Open CV视觉类库,实现True Type字体轮廓的提取技术。完成了激光标刻汉字的准备工作,为下一步打标的实现做出铺垫。
[Abstract]:With the development of science and technology, laser technology is becoming an indispensable new technology in our daily life, from military field to medical field, from industrial equipment to commercial application. Our daily lives are increasingly inseparable from the support of laser marking technology. Since the invention of laser in late 20th century, its role has not been replaced. In the invention of semiconductors, atomic energy. After the computer, laser technology, as the fourth great invention, gradually stepped onto the stage of history. It has high measuring precision, fast and accurate cutting technology, high and steady photon energy, and can be used as industrial measurement. Because of its high energy characteristics, laser is widely used in various fields at home and abroad. In recent years. Laser marking technology is gradually paid attention to. Laser marking technology is the use of the characteristics of high energy laser on the surface of materials for the marking of graphics. Laser marking is one of the most important applications of laser technology. Laser marking acts on a wide range of materials, from various metal materials, such as factory bearings, various hardware tools, to a wide range of non-metallic materials. Such as wood furniture marking, glass marking, ceramic fabric marking, plastic jewelry marking, rubber tool marking and so on, the realization of marking arbitrary images, text, bar code, two-dimensional code, to achieve marking serial number. Batch number, date. Laser marked characters can even be small to micron level, the anti-counterfeiting marking of commodities has an irreplaceable important use. Laser marking in addition to the wide range of materials. The range of patterns that can be marked is also very wide. In these patterns, especially the marking of Chinese characters is the most important. The marking of Chinese characters is mainly used in the field of industry. Because of the irreversibility of the marking of materials by laser, the anti-counterfeiting of the products has an insuperable significance for the marking of commodities. By means of laser marking, it is not only efficient but also clear and easy to understand. It is of great help to keep the beautiful degree of the product. In the background of laser marking, the first step of laser marking Chinese character engraving is realized. The purpose of this paper is to use VC language in the environment of Visual Studio. By using the quadratic Bezier curve and Open CV visual class library in computer graphics, the extraction technology of True Type font outline is realized, and the preparation of laser marking Chinese character is completed. For the next marking of the realization of making the groundwork.
