The aim of projective reconstructing is to estimate the position and direction of cameras through matching points in different images so lay the foundation for further reconstructing . on the basis of current methods of projective reconstructing , we used the levenberg - marquardt method to optimize the result of linear method so the precision is be improved , and we use the bundle adjustment method to entirely optimize the structure of scene and projective matrixes 本文在研究已有射影重建算法的基礎上,利用l - m算法對基于基礎矩陣的射影重建算法得到的線性結果進行優化,提高了算法的估計精度和穩定性,并在求得所有圖象對應的投影矩陣后利用bundleadjustment方法對空間結構及投影矩陣進行全局優化。

It can save many workloads of the next pick - up feature and feature matching . to suffice third dimension effect and reconstruction precision , first , obtain enough feature points by feature picking - up , and then use original matching arithmetic to obtain original matching points by taking covariance as comparability measurement . at last , match step by step that include use loose matching and lemds to remove the wrong matching points 為滿足真實感效果和重建精度,本文先通過特征提取和交叉匹配獲得足夠多的特征點;然后對采集到的特征點以協方差為相似性度量,利用初始匹配算法獲得初始匹配點集合;對匹配過程中產生的錯誤匹配點采用松弛匹配和最小中值法相結合的方法,進行分步匹配來剔除,滿足了精度要求。

The simulation results show that the feature point detection and tracking algorithm is feasible . next , matched points based essential matrix estimation is studied . the spacecraft attitude and position parameters are derived from essential matrix and the scale of motion is recovered with range information from laser ranger taken in account 再次,研究基于匹配特征點對的本質矩陣的估計算法,給出了由本質矩陣求取空間探測器的姿態信息和位置信息的方法,并且結合激光測距儀信息,得到探測器的運動比例參數,實現軟著陸過程的導航。

There are different thrusts and torques corresponds to difference trailing edge cutting value at different advance coefficients . combined with the real hull ' s resistance and the real engine ' s power and revolution , the matching point between hull - propeller - engine and the value of trailing edge cutting can be calculated 在得到不同的進速、不同的切割量下螺旋槳的推力、轉矩的情況下,結合實船的阻力和主機的功率、轉速等資料就可以計算出使船?槳?機匹配的切割量。

Aiming at this problem , we put forward an image - matching algorithm based on evolutionary algorithms . in our algorithm , we regard the image - matching problem as another kind of optimization problem that is looking for a most suitable matching point in matched image . then we use evolutionary algorithms to solve the problem effectively 本文針對這一問題,提出一種基于進化計算的圖像匹配算法,該算法將圖像匹配問題看成為一種尋找最優匹配點的全局尋優問題,從而采用進化計算方法來有效解決了該問題。

The algorithm firstly puts current frame and reference frame throug h a low - pass filter to get low frequency sub - images with quarter pixels , then attains the best matched sub - block by full search , at last the area of reference frame covered by the sub - block are searched to get the best matched point 該算法首先將當前幀和參考幀通過低通濾波器得到數據量減為1 / 4的低頻子圖,然后用全搜索得到最佳匹配的低頻子塊,最后對低頻子塊所覆蓋的原參考幀區域進行精細搜索得到最優點。

On the basis of the probability density function of the disparity gradient , the mutual coordinate constraint of the corresponding points of the two adjoing points in the continous edge of the left image was educed , then the search area of the matching point in the right image was limited 由視差梯度的分布密度函數,導出了左圖像連續邊緣上相鄰兩點在右圖像中的對應點的坐標間的相互約束關系,從而限定了右圖像中匹配點的搜索范圍。

In the algorithm , we look the image - matching problem as a kind of optimization problem that finds a most suitable matching point in matched image . then we use the strong global optimization capability of evolutionary computation to solve the complicated matching problem 該算法將圖像匹配問題看作為尋求最優匹配點的尋優問題,然后利用進化算法的強大的全局尋優性能來對圖像進行匹配。

Also appearing out of competition is woody allen , whose “ match point “ is set not in the veteran “ s favored manhattan but in london , and stars scarlett johansson 同樣在戛納亮相而不參加角逐的還有伍迪?艾倫執導的影片《最后一分》 。這部由斯佳賴特?約翰遜主演的電影以倫敦為背景,而不是退伍老兵喜歡的曼哈頓。

Lee , 31 , clinched victory on his third match point , when he ripped a forehand passing shot winner to break the scotsman ' s serve and end the two hour , 45 - minute match 31歲的李亨澤把握住了第三個賽點,以一記正手穿越致勝球破發成功,贏得了歷經2小時45分鐘的比賽的勝利。

Using the pwfm , it is easy to locate matching points accurately , and it yields fewer spurious responses than correlation matching . it is robust for almost all the images 該算法的優點是匹配點定位簡易、準確,虛警少,穩健性強,適用于各類圖象的匹配識別。

Davenport , the 1998 u . s . open champion , surged back from a poor first set to force a tie breaker , in which she saved two match points 1988年美國公開賽冠軍達文波特從第一盤的不利情況中掙脫出來,在第二盤中逼平對手,救了兩個賽末點贏得了該盤比賽的勝利。

He had two match points against nadal ' s serve in the 10th game and set up another with a backhand down the line from a wide angle in the 12th 費德勒在第10局納達爾的發球局中曾取得兩個賽點,接著在第12局以大角度反手回擊第三次拿到賽點。

Women ' s number one zhang ning saved three match points to beat fellow chinese xie xingfang 21 - 11 16 - 21 30 - 29 in their earlier singles final in tokyo 在下午進行的女單比賽中,中國選手張寧2比1戰勝謝杏芳,摘得本次比賽的女單桂冠。

This function returns the rest of the string ( from the matching point ) , or false , if the string to search for is not found 如果這個函數執行成功,將返回剩余字符串(存在相匹配的字符) ;如果沒有找到相匹配的字符,則反會false 。

He was down one set to love and he had a double match point against him in the second set tie break at 4 - 6 羅迪克先贏一盤,接著在第二盤搶七時以6 - 4領先,卻接連錯失兩個賽點。
