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.

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.
