To the influence of the plateau terrain, the impact of the elevation and the roughness of terrain to every energy component out and incoming are study, and basing the soil spectrum model proposed above, a new radiative transfer model of terrain area was put forwarded in which the soil water content, lai, terrain roughness and elevation were considered synchronously, and incoming scatter light was integral with the solid angle of semi - globe space defined by the slope of the pixel, so scattering lights of terrain and the sky are properly considered, but the operation is still within the acceptable range
地形與反射率的關系是本文研究的一個重點。本文對崎嶇山地象元的各入射光和反（散）射光分量進行了深入分析，在所提出的濕潤土壤光譜模型和植被冠層模型的基礎之上進一步提出了新的適合青藏高原的山地輻射傳輸模型。該模型同時考慮了土壤含水量、植被覆蓋（ lai ） 、地形起伏和海拔高度的影響，並以象元坡面定義的半球空間立體角對環境入射光進行積分，使周圍地形和天空散射光均得到適當考慮，計算量又在可接受范圍內。 -

In the coarse step, an improved klt ( kanade - lucas - tomasi ) algorithm is applied in feature extraction, and a new acceleratingalgorithm of template matching is presented to match features, and also a feasible feature validitytesting method is given. in the precise step, the “ regional counting method based onjoint - histogram ” is used for reference to make out its own improved method, which achieves “ sub - pixel ” precision as well as avoids heavy floating - point operation by clever definition ofcriterion function
粗配準過程中，利用klt （ kanade - lucas - tomasi ）的改進演算法進行特徵提取，提出一種新的模板匹配加速演算法進行特徵匹配，還給出了切實可行的特徵有效性檢驗方法;精配準過程中，借鑒「聯合直方圖區域計數法」的思想，提出具體的改進方案，通過巧妙定義準則函數使得演算法在避開大量浮點運算的同時達到了亞像素級精度。 -
