Laser Marking System Of Chinese Character Contour Extraction Technology

Today more and more developed in science and technology, laser technology is becoming an integral part of our lives in new technology. From the military sector to the medical field, from industrial equipment to commercial applications, more and more of our daily lives without the support of laser marking technology.Since the late 20 th century invented the laser, its role has been not been replaced before. After people invented semiconductor, atomic energy, computers, laser technology as the fourth invention gradually embarked on the stage of history. Its high accuracy, fast and accurate cutting technology, the photon energy is large and stable, can be used for industrial measurement, material cutting and light source. Due to its high energy properties, so that the laser used in various fields at home and abroad are extremely extensive. In recent years, laser marking technology is increasingly valued by the people. Laser marking technology is the use of high-energy characteristics of laser material surface graphical pattern of marking, laser technology is one of the most important applications. The effect of laser marking is very broad range of materials, from a variety of metal materials, such as plant bearings, all kinds of hardware tools, to a wide variety of non-metallic materials, such as wood furniture, marking, mark engraved glass, mark engraved ceramic fabric, plastic jewelry marking, rubber marking tools, etc., to achieve mark any image, text, bar codes, two dimensional codes, achieve marked serial number, batch number, date. The laser marking small characters and even to the micron level of security tags for goods has irreplaceable important uses.Laser Marking wide range of materials in addition to the role of outside, which can range marking pattern is very wide in these patterns, particularly in the marking of the most important characters. The main characters of marking applications in the industrial field, since the laser marking material has irreversible character, for marking goods, counterfeit products have unsurpassed significance. By laser marking text, not only efficient, but clear and understandable, small for the material damage, the extent to maintain product appearance has a great help.In this paper, laser marking of background, to achieve the first step of laser marking characters, namely extracting the outline characters. The purpose of this paper is under Visual Studio environment using VC ++ language, using computer graphics quadratic Bezier curves and Open CV vision library, achieve True Type font outline extraction techniques. It completes the preparation of laser marking characters for the next marking implement to make bedding.
