Abstract

In this paper, we propose a novel active 3D recovery method based on dynamic (de)focused light. The method combines both depth from focus (DFF) and depth from defocus (DFD) techniques. With this approach, optimized illumination pattern is projected on the object in order to enforce strong dominant texture on the surface. The imaging system is specifically constructed to keep the whole object sharp in all captured images. Consequently, only projected patterns experience the defocused deformation according to an object depth. Projected light pattern images are acquired within certain focused ranges similar to DFF approach, while the focus measures across these images are calculated for depth estimation by using DFD manner. This guarantees that at least one focus or near-focus image within depth of field exists in the computation. Therefore, the final reconstruction is supposed to be prominent to the one obtained from DFD and also less computational extensive compared to DFF provided.
