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。

Chen's eyes focus on the little industrial towns in the west part as well as big cities. His worries and meditation overflow from his camera lens, and are condensed into pictures with surreality.

陈家刚的目光停留在西部落魄的工业小镇上，也停留在繁华的都市中，他的焦虑与思索从镜头中漫溢出来，凝结在一幅幅超现实感的照片当中。

This paper has deduced the ion trajectory in an accelerating tube by integrating the one in a unit electrostatic lens.

离子在其中的运动轨迹与光学透镜系统中的光路相似，对此已早有研究，但对加速管聚焦特点的讨论还不够明确［1～3］，对离子轨迹的计算极为鲜见［4］。

Optimum design of focused transducers is studied, and the selection of thickness of lens and materials is discussed.

研究了聚焦换能器的优化设计，对透镜厚度及材料的选取进行了分析。

Crystalline lens and figure out what's important and what's not - I love this picture.

另外， 时间管理能够使你开始透过一片清晰的透镜来看清，哪些事情是重要的，哪些不是。

Crystalline lens is tissue structure which has the highest protein level.

晶状体是人体内蛋白含量最高的组织结构。

The fine focusing or accommodation of the human eye is a function performed by the crystalline lens.

人眼的精细聚焦或调节的功能是由水晶体执行的。

The other thing about time management that makes you really start to look through a crystalline lens and gure out what's important and what's not - I love this picture.

另外， 时间管理能够使你开始透过一片清晰的透镜来看清，哪些事情是重要的，哪些不是。我喜欢这幅图片。

All else limps behind Bliss fully in your wake.

所有其他limps在您的背后幸福之后。

The paper firstly locates Culler's position in structuralism from micro-aspect and macro-aspect and then from two levels of the subject construction and literature definition focuses on the foundation of Culler's poetics in aspects of linguistic procedure and institutional theory to find the theory premise of Culler's poetics.

本文首先从微观视野在结构主义内部和从宏观视野在结构主义外部为卡勒进行定位，以便寻找发展的契机。其次聚焦卡勒诗学的根基，从学科建设和文学定义两个层次，围绕语言学程序和惯例论立场，发掘卡勒诗学赖以产生发展的理论前提。
