目前,随着计算机科学的发展,特别是多媒体技术的出现,光盘技术的日趋成熟,把语音、图像、图形和文本等多种数据有机结合在一起,使人机交互对话成为可能。计算机软件和硬件的发展为多媒体技术开辟了广阔前景,对彩色图像和动态画面的处理技术不断涌现,对声音和国像等大容量数据的压缩存储算法日益增强,特别是ISDN网络、高速大容量可读写光盘、高分辨显示器、喷墨式绘图仪和高性能扫描设备的出现,为工程图纸的光盘管理奠定了必要基础。
At present, with the development of computer science, especially the emergence of multimedia technology, CD-ROM technology has matured, and many kinds of data such as voice, images, graphics and text are organically combined to make it possible for human-computer interaction dialogue. The development of computer software and hardware has opened up broad prospects for multimedia technology. The processing techniques of color images and dynamic images are constantly emerging. The compression and storage algorithms for large-capacity data such as sound and national image are increasing day by day. Especially ISDN networks, high-speed and large-capacity The advent of compact discs, high resolution displays, inkjet plotters and high-performance scanning equipment laid the necessary foundation for the management of optical discs for engineering drawings.
