| 应用层次数据格式(HDF)的文件格式与HDF应用编程接口,设计了机载多角度电力巡线系统三级数据产品的逻辑结构与物理结构,实现了其系统文件的创建、写入、读取等基本功能,在HDF科学数据集API基础上实现了栅格图像金字塔管理和多种数据类型转换等功能,并在此基础上完成了机载多角度电力巡线系统的开发。该系统采用一套对HDF API函数进行了封装的数据接口类库,用户通过调用接口类库中简单的读写函数可实现对复杂的系统HDF文件的读写操作,为不熟悉HDF API函数的用户操作HDF文件提供了方便。该系统的开发过程对于利用HDF数据格式处理和管理海量图像数据和属性数据具有一定的借鉴作用。 |

| Abstract: |
| The Hierarchical Data Format,HDF,is a multi-object file format for sharing scientific data in a distributed environment.The file logistic structure of an airborne multi-angle power line inspection system was designed by using HDF and its Application Programming Interface(API).Based on HDF scientific data API,the HDF data interface library was established to create,write and read files of the system.A power line inspection system was developed by integrating the HDF API and the library.The airborne multi-angle power line inspection system adopted a set of libraries with HDF API for easy use of customers.The developing procedure of this system gives a good example for application of HDF data format processing and management of huge amounts of raster image data and attribute data. |
