Title   Measuring system of geometry of steel sheet   based on multiple cameras                     

Abstract Measurement technology of steel sheet is the focus of the research at home and abroad。Multiple camera-based measuring steel sheet system, combined with image processing technology and without the touch on the steel sheet, is used to obtain steel sheet’s size information quickly and accurately。

It has a great potential in future applications。The development and current

status about measurement technology and measurement technology of steel

sheet at home and abroad are overall illustrated。And the project of multiple camera-based measuring system of geometry of steel sheet are designed and proposed。The hardware are selected and the system model are set up based on the actual situation。 The algorithms of the image processing are analyzed and the program of the system are completed by experiments and analysis。 The measurement results and the reasons of the errors are analyzed through simulation experiments。The feasibility of the multiple camera-based measuring 

system of geometry of steel sheet are verified。
