The basis of dynamics and simulation includes the iterative flyout angle algorithm to the solutions to lambert problem and battin ' s universal conic section state extrapolate method. then spacecraft ' s orbit roots, maneuver impulse and maneuver time are discussed as the following four part : first of all, the chaser ' s one orbit roots is selected as a variable to simulate its influence to the large scale orbital maneuver. the research reveals fact that the orbit roots both of chaser and target should be close to each other to achieve better maneuver and rendezvous " ability, moreover, the best orbit maneuver and rendezvous occurs when both chaser and target ' s initial phase angle are equal
為了研究了交會機動中追蹤器和目標器的軌道根數、機動時限和機動能耗等因素對交會機動的影響，模擬和分析分為以下四個部分:首先，研究了追蹤器軌道單個參數為變量情況下兩航天器大范圍交會機動問題，研究表明，追蹤器的變化參量與目標器相應的參量在接近的情況下可以獲得良好的交會機動特性，而對于兩航天器軌道共面的情況下，初始相位角相等時則獲得最佳的機動效果。 -
It is shown that a system of linear equations is resolved to obtain the rotational parameters by using of seven couple of conic curves in image sequences when the motion of a rigid object is pure rotational. when the motion of a rigid object is pure translation, a system of non - linear equations is resolved using iterative method, or using the method for resolving quartic equation. the translation parameters with a scale factor may be determined and the translation direction can be obtained
研究結果表明，在純旋轉運動分析中，最少利用圖像序列中7條對應二次曲線，可以線性地求解剛體旋轉運動參數；在純平移運動分析中，只需利用圖像序列中1條對應二次曲線就可以求解剛體相對平移運動參數（即平移方向） ，分別用非線性迭代法和一元四次方程解法求解了剛體相對平移運動參數（即平移方向） 。 -
By taking advantage of parallel lines and orthogonal lines in architecture, the camera internal parameters, rotation and translation can be recovered from a set of un - calibrated images via computing absolute conic and vanishing points. the euclidean 3d model of architecture ( up to a scale factor ) can be recovered too
利用建築物中常見的平行直線和正交直線等特點，通過絕對二次曲線和消影點等射影幾何量的計算，可以從圖象中恢復攝像機的內參數、旋轉和平移位置，同時恢復建築物的三維歐氏幾何模型（相差一個尺度因子） 。
