研究表明，對于城市活斷層的抗干擾高解析度淺層地震勘探，在數據採集環節應採用具有線性或非線性變頻掃描功能的可控震源和與其相匹配的地震儀器，以及小道間距、小偏移距、多接收道、短排列和高頻檢波器接收的工作方法；在數據處理與解釋環節，要重視折射靜校正技術、噪聲壓制技術、高精度速度分析技術、子波壓縮技術、子波零相位化技術和疊前偏移技術等的應用。Just as we scan a visual scene with our eyes, star - nosed moles constantly shift the star to scan tactile scenes as they travel through their tunnels, quickly exploring large areas with the eimer ' s organs of all 22 appendages
正如我們以眼睛掃描視界，星鼻鼴在地道里穿梭時，也持續移動星鼻來掃描觸界， ?們用上全部22個附器的艾瑪氏器，來快速探測大?圍的空間。In accordance with the phase - shift miscalibration and detector nonlinearity, the error - compensating phase - shifting algorithms based averaging technique are proposed. and in order to solve the problems brought by traditional linearity scanning unwrapping algorithm, which leads to incorrect phase unwrapping, a correlative region algorithm for phase unwrapping is developed
針對相移器的相移不準給相位求解帶來的誤差，提出採用基於平均技術的誤差補償移相演算法；針對傳統線掃描位相去包絡演算法不能對含有較大噪聲的位相圖進行正確去包絡的問題，提出了區域相關位相去包絡演算法。Second, the edge points on the scan - lines of the first prewarped image are detected and the corresponding points on the same scan - lines of the other prewarped image are matched. third, with these corresponding edge points, the scan - lines of the two images are segmented. in the end, more exact corresponding relation of these points are obtained under the use of the affine transformation and the auto - corresponding of the images are finished
該演算法首先矯正源視圖，使矯正後圖像滿足視點平移關系；然後檢測第一幅圖像掃描線上的邊緣點，再由這些邊緣點匹配出第二幅圖像上對應的邊緣點，利用這些對應的邊緣點再分割兩幅圖像中所對應的掃描線；最後用仿射變換建立較為準確的點與點的對應關系，完成圖像的自動匹配。In order to resolve the nonlinear distortion occurring in the course of image acquiring, first we apply affme transformation to adjust image, then recovery image by means of linear interleration algorithms
為了解決圖像掃描過程中出現的非線性畸變，首先運用仿射變換校正圖像象素位置發生的非線性移位，然後採用線性插值演算法進行圖像恢復。分享友人
