针对图书馆数据量巨大,重建工作量大问题,提出激光技术的图书馆数据重构策略。首先对图书馆数据重构过程中存在一些难题进行分析,找到它们产生的原因,然后将激光扫描技术用于图书数据扫描中,根据扫描数据实现图像数据的分类和整理,最后实现图像馆数据的重建。实验结果表明,该策略加快了图像馆数据重建的效率,重建的误差率低,可以降低数字图书馆数据维护的工作量。 Aiming at the huge amount of data in the library and the heavy workload of reconstruction, this paper puts forward the laser data reconstruction strategy of the library. First of all, some problems existed in the process of library data reconstruction were analyzed to find out the causes of them. Then the laser scanning technology was used in the scanning of book data, and the classification and sorting of image data were realized according to the scanning data. Finally, reconstruction. Experimental results show that the proposed strategy can speed up the reconstruction of image database and reduce the error rate of reconstruction, which can reduce the workload of digital library data maintenance.
