We propose novel methods for both techniques to monitor the surrounding area of a vehicle. For fisheye camera calibration, we proposed a novel photogrammetric calibration method using planar calibration objects together with a distortion model based on the design of the fisheye lens. By minimizing the residual error between observed and predicted image coordinates of feature points, a set of camera parameters that best describe the imaging process of the camera can be obtained.

在鱼眼摄影机校正中，我们提出基於摄影校正法的创新的校正方法，其中利用平面校正物进行鱼眼摄影校正，并以视野失真模型(field-of-view distortion model)作为鱼眼失真模型，透过降低摄影机校正误差进行非线性的摄影机参数最佳化，由已校正的鱼眼摄影机所拍摄的影像皆可经由失真校正将鱼眼影像还原至透视投影影像。

The camera length of electron diffraction in transmisson electron microscopy is one of the main technical parameters in designing electron microscope and the electron diffraction analysis to microcrystal sample. According to Bragg law, the formula of calculating TEM electron diffraction camera length is derived from the research on the ray path of electron diffraction images in TEM and the comparison on electron diffraction with ordinary electronic diffractometer. The difference of physical significance of electron diffraction camera length between TEM and ordinary electronic diffractometer is discussed.

透射式电子显微镜(Transmisson Electron Microcopy， TEM)中的电子衍射相机长度，是电子显微镜设计和对微晶体样品进行电子衍射分析的主要技术参数之一依据布拉格定律，经对TEM中电子衍射成像光路的探讨与研究，并通过TEM与普通电子衍射仪的电子衍射的对比分析，导出了TEM电子衍射相机长度的精确计算公式，阐述了TEM和普通电子衍射仪的电子衍射相机长度所表征的物理意义的区别。

According to this theory, the image was made with the aid of a magic lantern, a simple projecting device, or by means of a camera obscura and light-sensitive silver compounds applied to the cloth.

依照这个理论，这个图像是借助于早期放映机的帮助，一种简单的突出设备，或者利用暗箱和光敏感镀银混合物运用于布料上面。

It can get the three-dimensional profile of the object surface effectively. Because of the cragginess of the three-dimensional surface when sine grating is projected the image of the sine grating is modulated and the modulated image is taken by a CCD camera with an angel compared to projecting direction. After the phase shift measuring method, the phase is gotten. Because the phase is calculated by the phase shift measuring ranges from –π to +π it isn't continuous. The phase unwrapping is necessary to recover the continuous phase about the object shape.

这种方法采用结构光照明，将正弦光栅图像投影到被测物体表面，用与投影方向成一定角度的CCD摄像机获取受物体表面面形调制的变形光栅像，根据数字相移算法计算出相位分布，由于从相移计算的相位被截断在反三角函数的主值范围内，因而是不连续的，必须通过相位展开恢复出连续相位分布，由相位－高度关系最终求出物体轮廓的三维数据信息。

In this thesis, we propose a new semi-automatic system that is able to create interesting 3D effects from plain photographs. By directly projecting the ground plane without the use of camera parameters, we avoid the problem of creating images with wrong depth ratio and texture distortion.

本论文修改了还原真实场景比例的立体化方式，将影像中属於地面的部份，以原始大小直接投影至立体空间，这麼做出现了类似立体书或立体卡片的效果，同时也省去了设定相机参数的步骤，避免因不正确的参数设定导致错误的深度比例或材质贴图的扭曲变形。

Then the system parameters were gain from solving non-linear equation. First, the figure which the circle projecting on the CCD plane by the camera led is proved as an ellipse, and find out the reference point coordinate by calculate the canters of ellipses. Then the system parameters were gained from calculating the formulas in two pictures.

首先证明了参考圆在合适条件下经过相机镜头所成的像是椭圆，通过椭圆的中心求出参考圆的中心，就得到了各个参考点的位置；然后通过各个参考点分别在两个相机坐标系中的位置来确定相机之间位置关系参数，就完成了系统的标定。

Using the OMA optical multi-channel spectrometry , CCD(1152×1242) camera detect equipment and achromatic aberration camera lens for spatial distinguishing, we carried out the experiments to measure the one- dimension fine structure spectrum of 20 harmonics,and then investigated primarily the measurement system of scattering light.

Aim at the problem of high frame rate camera has not analog output and can not display on general monitor,a system that is used to display the image for high frame rate camera in real-time is designed.

针对高帧频数字摄像机没有模拟输出，不能在普通的视频监视器上显示的问题，研究设计了一种用于高帧频数字摄像机的实时显示系统。

In our eye it is called the pupil, in a camera it is called the camera aperture.

在我们的眼睛被称为学生，在一个摄像头，可以被称为相机光圈。

Yet, Edith says, there was always money in the bank.

但是Edith说，她的银行户口里面总是有钱。

We have created a series of files that resolve this problem--one for each day of the 40 days of purpose.

我们制作一系列的档案去解决这问题---一个为标竿40天中的每一天。
