| 摘 要： | 0IntroductionWelds quality is directly affected by the location accu-racy of welding torch to groove center in vision sensor robotwelding. Therefore, it is very significant to increase theextraction accuracy of groove center. A common method isto use high resolution CCD and high speed image collectingcard, but it costs high or sometimes there are limits inuse.Subpixel detection is an effective soft method to in-crease image location accuracy[1 -2]. Compared with chan-ging hardwares , it is v…
