敦煌石窟海量数据无差错传输系统的设计与开发

Design and Development of the Error-free Transmission System for the Mass Data of the Dunhuang Caves

本文针对敦煌石窟数字化海量数据在实际工作数据传输过程中出现的问题,认为海量数据无差错传输技术,在敦煌石窟数字化过程中是非常重要的一项技术。敦煌石窟海量数据无差错传输系统的设计与开发,为了开发出实用性强的软件,首先针对敦煌石窟壁画数字化工作流程、分析摄影采集、图像处理和数据存储各阶段的特点,提出了敦煌石窟海量数据无差错传输系统的需求;其次,设计了敦煌石窟海量数据传输校验方案,针对敦煌石窟壁画数字化工作流程提出了层级式校验,依据该校验思想,设计了数据校验的整体框架并做了优化,最后设计出数据传输校验的详细模型,确保了数据传输的完整性;最后,基于上述方案,设计并实现了敦煌石窟海量数据无差错传输系统,利用Visual Studio2010开发平台、C++程序开发语言完成系统的开发。此系统已在敦煌壁画数字化工作中实际应用,效果良好。

Error -free transmission technology used for the digital data of the Dunhuang caves is very important for resolving data transmission problems during actual work. The main work of this project is the design and development of an error-free transmission system for the mass data collected at the Dunhuang caves. Firstly, in order to develop practical software, we analyzed the characteristics of each stage, including photography gathering, image processing, and data storage, and then posited the requirement for an error-free transmission system for the mass data of Dunhuang caves. Secondly, we have designed a mass data transmission check scheme for this system. Based on the Dunhuang caves mural digital workflow, we recommended a process of hierarchical verification validation, designed and optimized the overall framework of data checking, then designed an exact model for data transmission validation, ensuring the integrity of data transmission. Finally, according to the above-mentioned scheme, we designed a working, error-free transmission system for the Dunhuang cave data. This system, developed with Visual Studios 2010 development platform and C ＋＋programming language, has already been applied in digital work on Dunhuang murals with good results.
