  1. Investigation using remote sensing ( rs ) technology can breakthrough the limits of traditional methods, make full use of its capability of integration, visualization, rapidity and vast - dimensions analysis, and get better results the paper takes the up - to - date landsat - 7 etm + data, which is the most widely used, and quickbird data, which has the highest resolution nowadays, and according the features of the data and landslides, processes the quickbird data with 1 : 10 000 dem orthophoto correction and the landsat - 7 etm + data as follows : ( 1 ) selecting optimal spectrum band : selects 753 bands as the optimal bands ; ( 2 ) image intensifying : selects the principle components processing method on the basis of comparing several image intensifying methods ; ( 3 ) rigour geometric direction : corrects the geometric distortion of the map ; ( 4 ) image fusion : mainly takes his space transform fusion and resolution fusion method, and acquires maps with higher spectrum resolution as well as space resolution. after that, the visual effect of the image has been enhanced, and the interpretation precision

    採用遙感技術，可以突破傳統調查方法的限制，發揮其宏觀、綜合、直觀、快速的特點，取得更好的效果。論文選取目前應用最廣的陸地衛星最新系列landsat - 7etm +數據和空間解析度最高的商業衛星quickbird數據作為主要的數據源，根據數據的特點及滑坡災害應用特徵，對quickbird遙感數據則基於1 ： 10000dem進行了正射校正，對etm +遙感數據進行了波段優選，選取了753作為最佳組合波段；圖像增強，通過各種增強處理方法的效果對比，選擇主成分分析法對圖像進行增強；幾何精校正，糾正圖像的幾何變形；影像融合，主要選取了效果較好的his空間變換融合和解析度融合，得到的圖像既具有較高的光譜解析度，同時也具有較高的空間解析度。經過上述數字處理，較好地改善了圖像的視覺效果，提高了圖像解譯的精度。
  2. Accordingly, the origin of geometric distortion is first introduced in this paper, and through analysis, a geometric correction algorithm is presented. applying the transformation of three - dimension - projection, image series are finally converted into the same coordinate system

    論文首先介紹了圖像幾何畸變的產生，並通過分析得到幾何畸變的校正演算法，通過三維投影變換把系列航空圖像變換為同一坐標系（地面坐標系）下的幾何畸變校正圖像。
  3. A 2 - d multinomial geometric correction quadratic model was used to correct the geometric distortion of images, and a file contents 6 parameters was used for images coordinates register. 5

    遙感圖像的幾何校正採用一個二次多項式模型實現，來消除平移、縮放、旋轉、仿射與彎曲等圖像變形；遙感圖像的坐標配準採用參數文件的方法進行。
  4. Image geometric correction based on distortion ratio

    基於畸變率的圖像幾何校正
  5. Some improvement is made in this dissertation based on compare and conclusion of existing methods and theories, such as substituting space - variant filter for range interpolation in geometric distortion correction and improving atafs, both of which are demonstrated to reduce computational burden effectively

    在現有的理論的基礎上，本文簡化了幾何校正通常所採用兩維插值，並且改進了wpfa和dda演算法，這些改進有效的提高了演算法性能。
