“…Without precisely estimating the defocusing blur, it would not be possible to obtain the proper reconstruction. Hinojosa et al developed a 3-D shape measurement system by using projections of cylindrical wavefronts on the object to extract the depth information of the objects from the defocusing structured light (DSL) image and recover the 3-D surface information [10]. However, this approach has not realized real-time 3-D shape measurement.…”
