A group of projective invariants is proposed for recognition of planar polygons.

4給出一組用于識別平面多邊形的射影不變量。

To solve the problems in adjusting and controlling shapes of developable surfaces, following the important idea of duality between points and planes in 3D projective space, two direct explicit and efficient methods of computer aided design for developable surfaces are proposed.

為了解決工程中可展曲面位置與形狀難以調(diào)整和控制的問題黄视频WWW，基于3D射影空間中點和平面間的對偶性這一重要思想欧美专区地址，提出了2種直接、簡單有效的可展曲面設計新方法一级啪啪啪免费视频。

Therefore, we proposed a plane image normalizing method based on projective transformation. This method is also suit for stereo image normalization under large disparity. 3久久AA视频、Object existence decision is needed before extracting disparity from stereo image.

考慮到通常立體視覺方法對兩個攝像機一致性的要求較高，不便于在監(jiān)控系統(tǒng)中安裝攝像機久久99con，我們提出了一種基于射影變換的平面圖像規(guī)格化方法国产综合亚洲一区二区三区播放，該方法對大視差條件下的雙目圖像規(guī)格化也具有較好的效果。

A new kind of method for recognition of planar object is presented based on steerable filters .

提出一種基于方向可變?yōu)V波器的平面物體射影不變性識別方法XXXX白人性与XXXX黑人。

We make use of a mapping known as stereographic projection.

我們作一個稱為球極平面射影的映射色狼av窝电影。

It is related inherently with the intersection angles among the lines that the vanishing point s correspond.

由此，本文提出了一種利用消失點列的射影不變量提取平面直線夾角的方法免费看黄色视频的网站在线观看。

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天天色狠狠干，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同心圓，所以在本文中网站看黄，我們首先提取鋼圈輪廓黄色日韩精品、鋼圈圓心和車輪與地面接觸點在圖像上的投影，然后利用射影變換保持交比不變的性質(zhì)求出車輪輪廓一级黄色片在线观看。
