The Graphic Input for a Laser-Induced Thermal Etching System

介绍了激光蚀刻、书写设备中的图形输入方法，着重讨论了图像预处理、直线段识别和圆弧识别的数学方法。

The method for the graphic input in a laser-induced thermal etching system and writingdevice is described.With a photoelectric type graphic and character scanner,all kinds ofexquisite patterns and characters can be rapidly and accurately inputted to a computer. Bymeans of the pixel recognition method presented,the lattice raster irnage is converted intovector information acceptable to the laser processing device. Mathematical methods for theimage preprocessing,line recognition and arc recognition are discussed at length. Themethod has been used successfully in the laser processing device.
