Automatic Adjustment of Television Sets Using an Uncalibrated Camera with a Novel Fuzzy Test Pattern and an Adaptive Alignment Algorithm

In this study we present the results of experimental research on an automatic adjustment system for television sets that relies on an inexpensive, uncalibrated camera to measure the geometric attributes of the TV screen and by using a closed-loop structure, sends adjustment signals which are generated by a computer to the television`s internal EEPROM. Also several image processing tools have been utilized to measure the geometric parameters of the TV screen through the output images obtained by the camera. Control strategies are used to adjust and stabilize these parameters. We have already proposed and published a novel fuzzy test pattern and an adaptive alignment algorithm which are both used in the present research. This approach is implemented in real-time in a manufacturing house.
