diminish

3 . characteristic points are established through projecting images of regular points to measured surface . space dimidiate coding method which is called rough match and correlation technology , centroid technology , corner detect technology which are called precise match are used to acquire characteristic points accurately 將空間規則點圖案投射到被測物體表面形成特征點,然后利用空間二分編碼粗略獲得空間特征點(稱為粗匹配) ,再利用自相關技術、質心技術和角點技術精確獲得空間特征點的圖像坐標(稱謂細匹配) 。

Then based on the method of dimidiate pixel model , the current model is improved , and the model of deriving vegetation fraction from normalized difference vegetation index ( ndvi ) 然后在像元二分模型的基礎上對已有模型進行改進,建立用ndvi歸一化植被指數估算植被覆蓋度的模型。
