unwrapped phase 中文意思是什麼
-
3 ) for weak noise interferogram or filtered interferogram, dyadic wavelet can be used to detect fringe edges. a gvf snake model was used to link discrete edges, the linked edges were kept well accordance with fringes of phase map. 4 ) phase unwrapping algorithm based on edge detection is suitable to well separated fringes, the unwrapped phase can be rewrapped to the original phase map
4 ）對于低噪聲情況下或濾波后的干涉條紋圖，在基於邊緣檢測的相位解纏過程中，利用snake模型可以高效準確的實現邊緣點的連接，所連接的邊緣線與干涉條紋很好的吻合，可將連線的精度控制在三個像元。 -

該方法克服了傅立葉分析方法的相位去包裹過程以及迭代演算法計算量大的缺點。 -
