Abstract:
|
A novel optical edge-projection method is proposed for surface contouring of an object with low reflectivity. A
structured light edge is projected onto a dark surface, and the image is captured by a CCD camera. The
object contour is evaluated with an active triangular projection algorithm, and one obtains a whole-field
three-dimensional contour of the object by scanning the optical edge over the entire object surface. The proposed
method is applied to a black nonreflective object made from woven carbon fiber and is also applied to
measure the profile of a small object (a coin). The results show that an accurate profile of the specimen can
be obtained. |
