Method and apparatus for noncontact surface contour measurement |
摘要 |
Light at known angles is impinged onto an object whose contour is to be measured and a camera is used to receive the reflected light which is then recorded. A computer processes the images, mathematically manipulating them so that surface slopes are known. The slopes are than integrated to obtain local elevations which represent the object contour.
