Based on interpretation and analysis of home and foreign relevant research, for the purpose of reducing the vibration of adjacent buildings induced by subway, the characteristics of buildings vibration induced by subway are studied by in situ experimental method and numerical simulation method. based on above analysis, a three - dimension isolation device is developed to reduce the buildings vibration, and its practicability and feasibility are tested and verified through numerical simulation method
本文在對國內外相關研究內容進行分析的基礎上，以減輕地鐵運行誘發沿線建築物振動為目的，用現場實測和數值模擬的方法研究了地鐵運行誘發鄰近建築物的振動特性和規律，並在此基礎上提出了減輕建築物振動的三維隔振裝置，同時對該裝置的適用性和可行性進行了數值模擬驗證。This paper takes jin ’ ao mansion and adjacent buildings as the study object. first we put the stated reduced scale model in the atmospheric boundary layer which the tunnel simulates, applied the dynamic pressure measure technology on the building ’ s surface to get the mean and fluctuating wind pressure coefficient, drew out the contour of pressure coefficient and analyzed its distributing law and characteristic
本文以金奧大廈及其鄰近建築作為研究對象，首先把一定縮尺比的模型置於風洞模擬的大氣邊界層環境中，運用建築表面動態測壓技術獲得金奧大廈表面的時均風壓系數和均方根風壓系數，繪制時均風壓系數和均方根等值雲圖並分析其分佈的規律和特點。An algorithm for detecting moving ir point target in complex background is proposed, which is based on the reverse phase feature of neighborhood ( rpfn ) of target in difference between neighbor frame images that two positions of the target in the difference image are near and the gray values of them are close to in absolute value but with inverse sign. firstly, pairs of points with rpfn are detected in the difference image between neighbor frame images, with which a virtual vector graph is made, and then the moving point target can be detected by the vectors ' sequence cumulated in vector graphs. in addition, a theorem for the convergence of detection of target contrail by this algorithm is given and proved so as to afford a solid guarantee for practical applications of the algorithm proposed in this paper. finally, some simulation results with 1000 frames from 10 typical images in complex background show that moving point targets with snr not lower than 1. 5 can be detected effectively
基於運動點目標在鄰幀差分圖像中所具有的近鄰反相特徵，即運動點目標的兩個位置相鄰近、灰度值一正一負，提出一種在復雜背景下，基於紅外序列圖像的運動點目標檢測演算法.本演算法利用該特徵在鄰幀差分圖像中檢測反相點對，進而構造反相點對矢量圖，最後依據累積反相點對矢量圖中多矢量首位相接的連續性檢測出運動的點目標.文中給出並證明應用本演算法能以概率1檢測到運動點目標的收斂性定理.對典型復雜背景下10幅1000幀圖像的模擬結果表明，當信噪比大於或等於1 . 5時，可以有效檢測出運動點目標
