To detect defects in quartz rods using machine vision technology, we need to get the image through the camera and transmitted it to a computer for next processing. The energy of laser will be produced when it passed the object, which makes it difficult to identify the resulting quartz rod boundary. This paper proposes a method of boundary detection based on Hough transform circle, and improves the Hough transform of some algorithms for solving the problem of the large amount of calculation.
