This thesis presents a method for 3D range acquisition using
color structured lighting and stereo vision. Since a pair of
stereo images are used, cameras are the only device needed to
be calibrated in this system. In this work, light stripes are
pro- jected onto the objects, and then edge segments are
extracted from the images and used in stereo correspondence. A
systematic procedure is proposed for generating good color
structured pat- terns. Using different parameters, different
color patterns can be generated by this procedure. We then
select a good one to project on the objects. To obtain correct
matching, a global search method based on the intra-scanline
dynamic programming is adopted.A winner-take-all scheme using
edge-based inter-scanline matching consistency is then proposed
to refine the results obtained by intra-scanline search.
Experimental results have shown that the proposed method can be
successfully used for range data acquisition.
