逆向工程技术在犁臂测量和建模中的应用（Application of reverse engineering technology in measurement and modeling of plough arm）
The application of.Txt technology in reverse engineering measurement and modeling of the plow arm who to his crotch. Afraid to talk to him, but opened his data again and again and closed it. With the heart of emotion, really can make people understand a lot of things. If one day, my signature no longer updated frequently, it will prove that I is very good. Application of reverse engineering technology in measurement and modeling of plough arm

I. Introduction to reverse engineering
In the modern society of information, the competition of manufacturing industry is becoming more and more fierce. The speed of product update has been accelerated, and the production methods are becoming smaller and larger. Reverse engineering emerges as the times require and develops rapidly.
Reverse engineering is to collect a large number of three-dimensional coordinate points from the physical object, and then establish the geometric model of the object, and then develop advanced technology of similar products. Reverse engineering is the reverse of the general design and manufacturing process. First of all, there are real objects and then there are models. The reverse engineering flow chart is shown in figure 1.

The reverse engineering process, including the shape of reverse reverse and reverse the material aspects of the practical application in the industrial field, including: the design of the new parts; the existing parts of the copy; the damaged or worn parts of the reduction; improve the accuracy of the model; the model of digital detection.
Two 、 three-dimensional data measurement of plough arm
1. data acquisition implementation conditions
In reverse engineering technology design, it is necessary to extract 3D data from the design ob
