摘要: 
本篇論文首先針對前濾波的特性及概念進行探討,接著我們利用一張帶有雜訊之水平單邊切模擬圖利用Sine-Cosine濾波法濾波之後,再來利用本實驗室所提出的調控式平行相位法執行一次來縮小Jump帶,有了Jump圖之後利用調低門檻值與分支切割技術來增進Jump的完整性,最後再利用區域搬移技術來完成相位重建,此法不僅還原速度快,對於帶有高雜訊的相位圖也能有一定的還原效果。

In this paper we discuss the characteristic and the concept of filtering first. Then after we utilize a simulation drawing with noise to use Sine-Cosine filtering,we use the adaptive parallel phase unwrapping algorithm that put forward in our laboratory once to come to narrow the jump area. When we have the jump map,we try to turn down jump map threshold value and use branch cut the technology to promote the integrality of the jump.Finally we ues the regional unwrapping technique to unwrap phase. This method not only unwrap fast but also get good result of phase unwrapping on simulation drawing with high noise.
