基于ActiveX技术的河道断面图信息提取

河道测量生产实践中,断面积标注、土方计算表编制等许多内业工作,仍以手工方式完成,耗时费力,且易出错。本文探讨运用ActiveX软件集成技术,提取河道横断面图上的信息,并对所提取信息处理和挖掘,自动完成断面积标注、河道清淤土方计算表编制等河道测量内业工作,达到了提高工作效率和工作质量的目的,无疑,该项工作具有极大的应用价值。

Method of information extraction from section map based on activeX technology

In the production of Hydrographic surveying,a lot of inside work are still completed manually,time-consuming and error-prone,such as dimensioning of Basal Area and table.This paper discusses extracting river cross-sectional information from CAD with ActiveX software integration technology,some information is also processed and excavated,and Basal Area and earthwork table are automatically completed.Therefore these works achieve greater efficiency and quality of work.Undoubtedly,it has great applied value.
