数控测图仪的DEM国际试验结果

A Report on the Participation of a DEM International Experiment by the Use of a Home-made Computer Controlled Digital Mapping System

    摘要
  • 摘要: 本文记述了国产象片坐标数字化器参加由14届ISPⅢ3组织的'DEM'国际试验的情况,分析比较了不同类型仪器的精度、速度、效率等。结果表明该仪器的精度、速度均不亚于国外同类仪器,而且成本也大大低于后者。

     

    Abstract: In this paper,the process of carrying out a DEM international experiment,organized by the ISPRS Commission Ⅲ in 1980 is described.The instrument used is a home-made Computer Controlled Digitel Mapping System including an Image Coordinate Digitizer.It has been found that so far as precision and speed is concerned,our hme-made instrument is superior as compared with other imported instrumnets.The cost is also much lower.
