  Abstract

In one VTR(Video Tape Recorder), two or more heads are used to record or reproduce video signals. To obtain a uniform quality of a VTR video heads should have similar characteristics such as geometrical shapes and electro-magnetic performances. This research is aimed to develop a visual inspection system measuring four geometrical parameters: H0,H1,Tw and CW. To obtain a high reliable results image processing algorithms were developed. A series of experiments was performed for one thousands of video heads. From observation of the experimental results, the system is found to show excellent performance for inspection of video heads.
