Research On The Precision Of Renewal Contour Map By The High Definition Remote Sensing Image

The question is that renewal contour map region broad, the current situation is worse, the cycle is longer, the expense is higher for the city, the factories and mines. Which is resolved through astronautics photographic survey technology. This article renews the Shenyang mining area 1:2,000 contour map by the QuickBird remote sensing image as the research backgrounds. the research to its process to propose method through the digital grid data and the vector data matching superimposition renewal contour map and the technical flow. And to renews its precision to carry on the examination. Also This article make some region as tests the region has carried on the thorough discussion to its image geometry correction precision. And proposed based on the spatial interpolation image correction precision spatial visible expression theory. Establish the distance reciprocal power space interpolation mathematical model and utilize the Matlab realization space interpolation and the visible. Manage the image correction of the precision equivalent lines, the precision gradation charts as well as the precision three dimensional visual pictures expressed any point the precision. Knows various regions the correction quality. Discovered the influence factor on the correction quality as well as the precision distributed rule. Obtains the selection control point rule for the image correction. Finally narrated the method and process of the remote sensing image facture in this mining area.
