noise ranging
解釋
噪聲測距-
Finally, a new 3d surface ranging method based on a digital fringe projection and shifting technique is systematically studied and non - linear rectification algorithms which reduce measurement error is proposed. at the same time, the noise - immune phase unwrapping algorithm is deeply studied and a new algorithm for phase unwrapping of phase map is proposed. experiment make known the algorithm can reduce measurement error, bypass the noise points automatically, solve the problem of the shade sheltering or cavity, overcome the error propagation problem and better results have been obtained
論文最後系統研究了基於數字相移條紋投影曲面三維測量方法，創造性地提出了一種減小測量誤差的非線性校正演算法，取得了預期的效果；同時對相位去包裹演算法進行了較深入研究，提出了一種噪聲圖像相位去包裹方法；實驗表明該方法能減小非線性測量誤差，自動避開噪聲點和間斷點，獲得了滿意的結果。 -
This paper gives us too ways ： one is to adopt a better modulation mechanism, s - cdma, to bate noise jamming. the other way is to implement automatic frequency agility under strong noise, based on the ranging and burst configuration mechanism of current docsis protocol, meanwhile, guaranteeing cmts ' s normal operating. this paper comprehensively analyzes the anti - jamming mechanism of docsis, then presents the specific implementation of the latter method
如何降低噪聲對網路的危害，本論文指出了兩個方向，其中一個就是在調制體制上下工夫，採用s - cdma體制，通過改變調制方式來主動的抑制噪聲的影響；另一個方向就是基於現在協議提供的抗噪聲干擾的機制，充分挖掘測距機制和靈活的突發配置機制的抗干擾潛力，以不影響頭端設備的正常運行為前提，以它們為基礎實現能自動避開強噪聲干擾的頻率轉移。 -
