Abstract
The inspection of dimension and shape of machine product is an important and essential part in the modern produce.Especially as the advancing of extent of robotization in the produce process,the human's vision inspection and general contact measurement could mot satisfy the request of modern industry field more and more.So the technic development of uncontact measurement is more and more important.Machine vision technology is a new means,which is attached importance to widely.
Pipe bender is the leading equipment which achieve bending and figuration pipe material,is widely applied in aerospace industry、chemical industry、furniture industry、war industry、motorcycle industry、autocar industryand so on,and as the development of modern manufacturing,pipe bender is requested better and better in the use performance,and is also requested having a break in the adaptability efficiency and precision.Especially the aerospace industry、autocar industry、energy industry、war industry、shipping industry etc,in which demands highly precise roboticized pipe bender.
In this article,Machine vision applies for measurement of curving angle of pipe bender through selecting hardware model,constructing measurement systema,acquising image,enhancing image,image processing arithmetic,indication of positions of ,analysing error,actualizing by LabView and so on facet.
On the key arithmetic ifluencing precise,through analysing the condition and characteristic of the object,consulting large numbers of literature at home and abroad,analysing and comparin arithmetic,and finally choosed the most suitable arithmetic,proofed reliability and feasibility of system in theory and actual facet.
Key words:pipe bender; LabView&IMAQ;Machine Vision;rdimension inspection
