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

免費線上英文唱歌的英文線上學中文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

Since ir images possess the characteristics such as pure data and plain, it can be operated in computer and produce dynamic images to simulate the features of the infrared as well as its movement contrail

紅外圖像是一種純數據、無格式的灰度圖像。模擬時將對象的動態特性和紅外特性通過建立數學模型、編程，在計算機上運行產生動態圖像，模擬目標的紅外特性和運動軌跡。

In view of the shape character of fw core, we should analyse the fw contrail subsectionly. certainly, the demarcation points must be considered to link them up through uniting the 3 - d coordinate and making the central angle 9 to be variational parameter

由於fw運動方程是一組分段函數，為了表達fw線型的連續性，必須考慮分段點的銜接問題，統一x 、 y 、 z三維坐標的參照系。

Because computing exactitude contrail is completed after the event by shooting range photic measure equipment, better quality track record to image collected by photoelectricity sensor become a very important work it exists the problem of data transmission rate low in the process of storing data to hd from high frame frequency and great array ccd camera

由於靶場光測設備對目標精確軌跡計算的工作要在事後完成，因此對光電傳感器採集到的圖像數據高質量記錄就成為一項極其重要的工作。從電視測量系統的高幀頻、大陣列的數字ccd像機採集並存儲數據到硬盤的過程中，存在數據傳輸速率低不能滿足要求的問題。
