It's actually quite easy to drive a car. The difficult part is to find your way. First you need to learn to drive in reverse. When you drive in reverse the rear-view mirror is not very useful because it can't reflect a large area, so you normally have to turn your head around and look behind.

2其实看车很简单，只不过要认识路是一件很难的事首先你要知道怎么倒车，倒车的时候是用不上后视镜的，因为后视镜不能展现出很大的区域分为，所以在一般情况下都要把头转到后面去看。

A reverse measurement system about the data collecting of 2-D object edge based on machine vision is discussed,in order to realize digital data input of the dimensions of 2-D object complex edge. This system realized calibration in large scene by virtual grid calibration method, and advanced the precision of system by using double CCD cameras. It realized data mergence by setting up referencer of regular shape. Some methods were put forward to realize graphics vectorization such as using eight-chain code difference to search for the turning points, and using change-length subjunctive beeline to distinguish linetype. The output data use the general DXF document format to connect the software of CAD. Research indicated that this system can be applied in reverse measurement to the dimensions of 2-D object complex edge.

对机器视觉二维反求测量系统进行了研究，以实现二维复杂平面边缘尺寸的数字化录入；采用虚拟网格技术实现大场景下的测量标定；利用双CCD分区域获取图象，通过设置规则参照物、数据拼接等数据处理提高测量精度；提出了利用8-链码的&链差&确定转折点，用&变长度虚拟直线&判断线型实现图形矢量化的方法；数据输出采用通用的DXF文件格式实现与CAD软件的接口；研究结果表明，该系统能够应用于二维复杂平面边缘的反求测量。

This paper presents a method, which uses the vortex sensor for gathering location signals of the narrow groove. In terms of the symmetrical characteristic of the edge of the signal, the paper adopts "reverse sequence cross correlation" method,i.e. cross correl ation analysis between the reverse sequence and original signals. This method makes full use of all the process of the signals, filtrating the stochastic signals, and can precisely locates the center of the groove.

文中采用了电涡流传感器来采集窄槽的位置信号，利用信号边沿部分对称的特点，采用了&倒序列相关&的方法，即用倒序信号与原信号进行互相关分析，充分利用了信号的全过程，滤除了信号中的随机成分，精确地求得窄槽的中心位置。
