The circular points are really a degenerate conic . 虛圓點(diǎn)實(shí)際上是一退化的二次曲線。
In the solving of absolute conic images , a novel circular point based method is used . the experiments show that the algorithm is feasible 其中在絕對二次曲線的像的求解中研究了一種使用虛圓點(diǎn)的方法,實(shí)驗(yàn)結(jié)果表明該算法是行之有效的。
In the investigation of virtual scene blend rendering techniques , because the 3d object imaging is related with camera interior parameter and exterior parameter , a self - calibration method based circular point is put forward 在虛擬場景混合繪制技術(shù)研究中,由于三維空間中物體的成像與攝像機(jī)的內(nèi)外參數(shù)是密切相關(guān)的,我們提出了一種基于圓環(huán)點(diǎn)的攝像機(jī)自標(biāo)定方法。
This paper presents the images of circular points of the plane on which the 1d object translates , the constraints of circular points to camera intrinsic parameters , and the numerical solution to the constraints equations ( and then we obtain the camera intrinsic parameters ) 摘要給出了平移運(yùn)動的一維物體所在平面的虛圓點(diǎn)圖像及其對攝像機(jī)內(nèi)參數(shù)的約束,和約束方程的數(shù)值求解方法,從而獲得攝像機(jī)的內(nèi)參數(shù)。
In 3d space , points on the infinite plane compose the absolute conic , and it contains the interior parameter information of camera . we use photography geometry character of circular point on the absolute conic to calculate camera interior parameter , exterior parameter can be obtained . we can obtain more accurate 在三維攝影空間中,無窮遠(yuǎn)平面上的點(diǎn)構(gòu)成了絕對二次曲線,由于二次曲線的像包含了攝像機(jī)的內(nèi)部參數(shù)信息,我們利用了圓環(huán)點(diǎn)的像在二次曲線上的攝影幾何特性,從而確定攝像機(jī)的內(nèi)部參數(shù),進(jìn)而求取攝像機(jī)運(yùn)動的外部參數(shù)。
