Machine vision differential measurement system |
摘要 |
In the present system, the thickness of an object with two surfaces is determined by forming two geometric images on the surfaces in a superimposed relationship. The images are viewed by two video cameras and their relative positions with respect to two corresponding references are determined. These relative positions are used to measure the thickness of the object.
