本发明将涉及一种可以防止发生设在屏幕前面的滤光片的弯曲和变形的图像显示设备的屏幕滤光片固定结构，具有下述的结构特征：设有从背面投射的光线得以结像的屏幕；设有设在屏幕前面的滤光片；设有安装在滤光片背面一定位置上的形成有针孔的托架；设有使滤光片固定到机壳上的，而且形成有挂钩，以便能插入针孔中的支撑架。

In Higher geometry , one of important points is to study graphic invariance and invariant in terms of projective trans formation and the feafures of prime and combination are its main and constant oners.

在高等儿何中，它的一个重要内容是研究图形在射影变换下的不变性和不变量，而同素性和结合性又是它的主要不变性质。

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.

由于提取钢圈轮廓比提取车轮橡胶轮廓容易，而且钢圈轮廓和车轮轮廓可以近似看作同一平面上的两个同心圆，所以在本文中，我们首先提取钢圈轮廓、钢圈圆心和车轮与地面接触点在图像上的投影，然后利用射影变换保持交比不变的性质求出车轮轮廓。
