A camera calibration method with co-line points is proposed, in which distortion center is located according to cross ratio invariability, and then distortion coefficients are calculated based on a line's central projection is a line.

摘要提出一种用共线点列标定摄像机镜头畸变参数的方法，先根据交叉比不变性确定畸变中心，再利用直线的中心投影仍为直线这一性质确定畸变系数。

The vanishing points of all lines in the same plane are colinear at the vanishing line of the plane.

The theory of current straightness measurement of 2 points equidistance is studied deeply in this paper, based on which, a new method of on line measuring of generatrix straightness for the cylindrical workpiece is presented.

本文对现行的双测头等截距测量直线度理论进行了深入的研究。在此基础上，提出了一种圆柱形工件素线直线度误差在线测量的新方法。

I've stitched Euclid's parallel postulate on to the surface. And the lines look curved. But look, I can prove to you that they're straight because I can take any one of these lines, and I can fold along it. It's a straight line.

我将欧几里德平行公设编织到表面上，这些线条看起来是弯曲的，但你看，我可以向你证明它们是直线；因为我可以拿起任何一条线，我可以沿线折叠，这是一条直线。

The display includes signal lines including scan lines and data lines intersecting the scan lines, both arranged along straight lines.

该显示器包括信号线，信号线包括扫描线和与扫描线相交叉的数据线，扫描线和数据线都沿直线延伸。

The experiment was divided into two parts: linear guidance and waypoint guidance by satellite. In order to get a better result for linear guidance, the four parameters "rud","ctr","yau", and "trn" of the Pilot model for Autopilot were properly selected. Here, the GPS receiver was used only for collection of satellite signals and storage of data.

实验分为自线导航与卫星导航两部分：在直线导航中，修改自动导航器Pilot模式下的rud、ctr、yau和trn四个参数，藉以找出直线行进时较理想的状况，此时的GPS接收机仅做为接收卫星讯号并记录之用。

METHODS: Oblique sagittal T1 weighted MR imaging at closed mouth was obtained from 88 joints of 44 patients who complained of unilateral TMJ pain. On MRI view, a straight line AE was drawn through the lowest point of articular eminence and the highest point of external auditory meatus, and then the perpendicular lines were dropped from condylar head and the most poterior band of the disc to AE on which the cross points were marked as C′ and D′.

关节盘移位程度的测量方法：MR成像层面上关节结节最下点到外耳道最上点的连线为直线AE，髁突顶点及关节盘最后点与直线AE垂直相交点分别为C′、D′，分别求得AD′距离、C′D′距离，代表关节盘在关节窝前后方向的位置。

First of all, this paper derives pressure expressions of stable state about vertical well inanisotropic media with various boundary. Based on this, Formulae of pressure distributionfor five-spot pattern and nine-spot pattern have been established, the characters of isobariccontours and streamline are analyzed, and this equips optimum of well pattern with theoreticfoundation.

首先利用坐标转换及镜像反演理论，推导了单一直井直线边界、平行直线边界的定常渗流的压力分布公式，在此基础上研究了五点法井网、九点法井网定常渗流问题，推导了压力分布方程，分析了等势线及流线的特点，为各向异性储层井网优化提供了理论基础。

It is not difficult to extract simple information such as road lane mark and the relative position of vehicle on the road from the machine vision sensor, so we have made some improvement on the lane mark identification and tracking technology including using a method based on Zernike Moment line detection algorithm, and then use lane mark features to extract the lane marking feature point, and use linear regression method to extract lane mark parameters.

因为在本文研究中通过机器视觉传感器提取的信息相对比较简单，只是提取公路的车道标识线以及车辆在车道中的相对位置，所以改进了基于机器视觉的车道探测方法，包括文中采用了基于Zemike矩的直线检测算法，然后利用车道标识线特征提取出图像中的车道标识线特征点，再采用线性回归的方法提取出车道标识线参数。

Horizontal alignment of a road is defined by polyline (straight line, circular curve, transition curve).

道路路线是由不同线元（直线、圆曲线、缓和曲线）组合而成的，随测点与哪个线元相关。
