Abstract:
Establishing reliable dense correspondences is crucialfor many 3-D and projector-related applications. Thispaper proposes using temporally encoded patterns todirectly obtain the correspondence mapping between aprojector and a camera without any searching orcalibration. The technique naturally extends to efficientlysolve the difficult multiframe correspondence problemacross any number of cameras and/or projectors.Furthermore, it automatically determines visibility acrossall cameras in the system and scales linearly incomputation with the number of cameras. Experimentalresults demonstrate the effectiveness of the proposedtechnique for a variety of applications.
