Two pairs of vanishing points of orthogonal directions from each image are obtained by using the concept of cross ratio and harmonic conjugate in projective geometry and the orthogonal property of the two diagonals on a square. All intrinsic parameters are calculated linearly after capturing the template from at least three shooting angles. Errors of edge detection and line fitting are avoided because the method does not require image matching.

充分利用了射影幾何中交比和調(diào)和共軛的知識以及正方形模板對角線相互垂直的性質(zhì)免费AAA一级，根據(jù)一幅模板圖像可以得到兩組相互正交的消失點(diǎn)連線，在至少三個(gè)不同方向拍攝的圖像上線性求解出攝像機(jī)的所有內(nèi)部參數(shù)福利网址在线观看。

In this dissertation, applications of cross-ratio in shadow generation and identity verification are investigated.

在本篇論文中美国毛片AAA在线播放，我們應(yīng)用交比發(fā)展了產(chǎn)生線光源影子的方法，以及利用交比進(jìn)行臉孔辨識的系統(tǒng)国产精品久久久精品一级。

That is, for every circle the cross-ratio of its four intersection points with neighboring circles is equal to a negative constant.

As the contour of a wheel rim is easier to detect than the contour of a wheel, and the contour of a wheel rim and the contour of a wheel are approximately concentric circles on the same plane, we first detect the contour of the wheel rim, the center of the wheel rim and the contacting point between the wheel and the ground, then we detect the contour of the wheel via the invariance of cross ratio under projective transformation.

由于提取鋼圈輪廓比提取車輪橡膠輪廓容易，而且鋼圈輪廓和車輪輪廓可以近似看作同一平面上的兩個(gè)同心圓wwwwⅹⅹxx，所以在本文中国产射射爽爽，我們首先提取鋼圈輪廓、鋼圈圓心和車輪與地面接觸點(diǎn)在圖像上的投影福利午夜国产一区二区三区，然后利用射影變換保持交比不變的性質(zhì)求出車輪輪廓A4yy午夜一级。
