The modular construction, used in the software of the system, consists of image input, output, processing, editing and analysing units as well as image database and graphics processing device. 该系统的软件采用层次模块结构。它包括图象输入、图象输出、图象处理、图象编辑、图象分析、图形处理以及图象数据库。
A digital image should be converted to the image of the same depth as the depth of image output device. 数字图像在输出前必须转换成与输出设备深度相同的图像。
Image acquisition system mainly included: plasma arc generator, optical filter device, CCD image sensor and image display output device. 为采集到加工状态下的非对称等离子体弧图像,论文自行设计搭建了图像采集系统,主要包括:等离子体弧发生装置,光学滤光装置,CCD图像传感器和图像显示输出装置。
