  Active range sensing using structured-light is the most accurate and reliable
method for obtaining 3D information. However, most of the work has been limited
to range sensing of static objects, and range sensing of dynamic (moving or
deforming) objects has been investigated recently only by a few researchers.
Sinusoidal structured-light is one of the well-known optical methods for 3D
measurement. In this paper, we present a novel method for rapid high-resolution
range imaging using color sinusoidal pattern. We consider the real-world
problem of nonlinearity and color-band crosstalk in the color light projector
and color camera, and present methods for accurate recovery of color-phase. For
high-resolution ranging, we use high-frequency patterns and describe new
unwrapping algorithms for reliable range recovery. The experimental results
demonstrate the effectiveness of our methods.
