When you install a fisheye meteors will disappear altogether.

当你安装鱼眼时（一种视场接近180度的摄影镜头），所有流星都会消失。

We presents an accurate F method based on corresponding point adjustment.The method adjusts coresponding points according to the fixedness of projective transformed cross ratio,then calculates F matrix accurately through linear and non-linear methods. When computing intrinsic parameter,A matrix,we simplify the step,and stress on the two important parameters of A.The result will be getten through solving Kruppa equation based on SVD decomposition.In order to compute extrinsic parameters,we use linear method to get initial R and t,then apply non-linear method to accurate them.

提出了基于匹配点调整的F求精方法，先根据摄影交比不见性对手工选择的匹配点进行调整，再用线性、非线性结合的方法求精F矩阵；在计算内部参数A中，进行了一定的简化，把重心放在A中重要的两个参数上，用SVD分解法计算Kruppa方程；在计算外部参数时，首先用线性法求解R、t，然后再用非线性法迭代求精。

I'm flattered, but I enjoy taking pictures, and I want to continue doing that.

我感到很荣幸，但我喜欢摄影，并且继续做下去。

This exhibition aims to slightly describe the details of conceptual photography through the works by the eight photographers-it does not intend to spread the flaunty fame of concepts, instead, it wants to explain the diversity of photography means, as well as the points of views and opportunities of photographers in their themes.

并不以"观念"的虚名妄世，只想通过对图像自身的描述，说明摄影方式的多样性，丰富性，还有摄影师在自己主题中表述的观点和机遇。

It is due to the quality of the photographer and their closed mind, as well as to the bad habit of Sichuan people-fond of fighting; it is associated with the separation between the official and folk cultural sector, and also with the bad habit of flaunty and idle commercial spirit.

此展览就是想通过八位摄影师风格迥异的作品，稍事勾勒"观念摄影"的微末细节。
