quickbird 中文意思是什麼

At last, the paper interprets the geological background of the forming of landslides, and reveals the landform, stratum, lithology and geologic structure based on the etm + image. and also, the paper interprets the location and distribution of the specific disaster bodies based on the quickbird image. through the analysis of the extracted information, the paper considers : the geologic structure of fengjie county is complex, and lithology is crashed ; the terrane in the canyon segment is fairly stable ; the terrane in some segments of the southern bank will be less stable after the water is stored, because the rock is in the same direction and is apt to slip with human project

最後在etm +圖像上對滑坡發育的地質背景進行解譯，提取了地形、地層巖性、地質構造等信息，在quickbird影像上詳細地圈定了滑坡災害體的實體位置及發育范圍，通過對所提取信息進行分析，本文認為，奉節縣地質構造復雜，巖性破碎；峽谷段巖層穩定性較好；南岸部分地段為順向巖層分佈區，人類工程活動容易誘發順層滑坡，蓄水后庫岸整體穩定性下降。

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。
