ABSTRACT

Typically welded bellows are checked with human eye and microscope, and then go through leakagetest of gas. The proposed system alternates these heuristic techniques using support vector machines. Image procedures in the proposed method can cover the irregularity problem induced from human being. To get easy observation through microscope, 3D display system is also exploited. Experimental resultsfrom this automatic measurement show the welding detection is done within one tenth of permitted errorrange.
