摘　　要：不同标准的矢量图件难以相互转换,导致图件信息共享存在障碍,空间数据的利用率较低等一系列问题。为此,以符号双向映射和像素匹配作为基本原理,利用数据库与GIS技术设计实现了基于像素匹配的矢量图件标准转换系统。系统主要通过标准符号库获取、符号映射关联表构建、图件符号解析、符号匹配与识别、目标标准符号获取和符号标准转换实现矢量图件标准转换。实际工作中的图件在三大石油标准间的相互转换实例结果表明:系统不仅具有运行稳定、操作简便和自动转换的特点,而且具有较高的转换精度和较强的实用性,可以很好地解决石油领域不同标准图件信息难以共享和空间数据利用率低的问题。The vector drawings of different standards are difficult to convert to each other,which leads to a series of problems such as the difficult sharing of the map information and the low utilization of spatial data. Therefore, based on the principle of symbol bidirectional mapping and pixel matching, a vector map standard conversion system based on pixel matching was designed and implenlented by means of database and GIS technology. The implementation of vector map standard conversion is mainly by the acquisition of standard symbol library, the construction of symbol mapping correlation table, the analysis of map symbols, the matching and recognition of map symbols, the acquisition of target standard symbols and the conversion of symbol standard. The system was applied to the mutual conversion between three major petroleum standards, and the verification results show that the system not only has the characteristics of stable running, simple operation and automatic conversion, but also has high conversion accuracy and strong practicability. It can well solve the problems such as the difficult sharing of the map information and the low utilization of spatial data in petroleum industry field.
